Understanding 404 and Other Common HTTP Errors

Original Source: https://www.hongkiat.com/blog/common-http-errors/

Have you ever encountered a puzzling “404 Not Found” message or other HTTP errors while browsing the web and wondered what they actually mean? Understanding HTTP status codes is not just a curiosity – it’s a necessity for website owners and tech enthusiasts alike. In this comprehensive guide, we’ll dive deep into the world of HTTP errors, from the well-known 404 to the more obscure 500 series.

Our aim is to demystify these error messages, explain their causes, and provide practical solutions for both web users and website administrators. Whether you’re looking to enhance your website’s user experience, improve its SEO, or simply satisfy your tech curiosity, this guide has got you covered. Let’s explore the fascinating world behind these error codes and learn how to effectively manage them for a smoother web experience.

Decoding Status Codes

Every error page online is associated with an HTTP status code from the server. These codes are three-digit numbers, with the first digit defining the code’s category:

1XX status codes are informational
2XX signals successful operations
3XX denotes redirections

These first three categories don’t lead to HTML error pages. In these cases, the client knows the next steps and proceeds without issue. The more noticeable codes are the 4XX and 5XX types:

4XX codes point to client-side errors
5XXs indicate server-side issues

HTML error pages appear in these scenarios because the client is unsure of how to proceed. Let’s delve into what occurs behind the scenes during these errors and how to handle them.

Client-Side Errors (4XX)
400 – Bad Request

When a server can’t understand a request from the client, a 400 Bad Request error appears. This often occurs when the browser’s data doesn’t follow the HTTP protocol rules, leading to a request with malformed syntax.

400 Bad Request Error Page400 Bad Request Error Page

A 400 error typically suggests an issue on the client side, like a compromised operating system, unstable internet connection, browser errors, or cache issues. It’s wise to troubleshoot your device first—try opening the webpage in a different browser, clear the cache, or check for security updates. Consistent 400 errors across various sites might signal the need for a thorough security check of your PC or Mac.

401 – Authorization Required

A 401 Authorization Required code appears when accessing a password-protected webpage. Initially, you’ll see a popup for login credentials rather than a direct error message.

401 Authorization Required Page401 Authorization Required Page

If you have the right credentials, you can access the site. If not, you’ll be redirected to the Authorization Required error page. For website owners, you can implement this protection through your cPanel account.

Setting Password Protection in cPanelSetting Password Protection in cPanel

To add password protection, go to the “Password Protect Directories” option in the “Security” section of cPanel. This is an effective way to secure areas like the wp-admin folder in WordPress sites.

403 – Forbidden

The 403 Forbidden error occurs when the server refuses a client’s request without an explanation. It’s not due to malformed requests or authorization issues.

Common causes include restrictions set by website owners against browsing the site’s file directory or certain files not being permitted for web viewing.

403 Forbidden Error Page403 Forbidden Error Page

Setting up a 403 error can enhance your website’s security by concealing its directory structure or sensitive files. Many web hosts offer this protection by default. To add it manually, access the Advanced section in cPanel and select Index Manager.

Configuring Index Manager in cPanelConfiguring Index Manager in cPanel

Here, you can control how visitors interact with specific directories on your site. Choosing No Indexing will result in a 403 error for anyone trying to access that directory.

404 – Not Found

The 404 error is the most recognizable HTTP status code. It’s displayed by the browser when the server can’t find the requested location. This can happen if a visitor mistypes the URL, or the site’s permalink structure has changed, leaving old links pointing to non-existent pages. Sometimes, 404s occur on top-level URLs, often due to a recent server move where the DNS still points to the old location. These issues generally resolve themselves quickly.

404 Not Found Error Page404 Not Found Error Page

Despite some SEO experts suggesting otherwise, Google states that “404 errors don’t impact your site’s ranking in Google, and you can safely ignore them.” However, it’s still beneficial to minimize 404s as they can increase your site’s bounce rate. A common solution is to use 301 redirects for permanently removed pages and 302 redirects for temporarily unavailable ones.

408 – Request Time-Out

A 408 Request Time-Out error occurs when a client’s request takes too long, leading the server to time out and close the connection. This happens if the server doesn’t receive a complete request within its waiting timeframe. Persistent 408 errors could be due to heavy loads on the server or the client’s system.

408 Request Time-Out Page408 Request Time-Out Page

Occasionally, both the client and server are functioning correctly, but temporary internet surges can delay message delivery. Like with 404s, many websites customize their 408 error pages. Typically, a simple page refresh using the F5 button can resolve a 408 error.

410 – Gone

The 410 Gone error is similar to the 404 but with a key difference. While both indicate the server can’t find the requested file, the 410 error explicitly signifies a permanent condition. It tells the client that the resource was deliberately made unavailable and that any incoming links should be removed. Unlike the 404, which leaves room for uncertainty about the file’s permanence, a 410 error is a definitive statement.

410 Gone Error Page410 Gone Error Page

For those managing servers, it’s important to know how Google crawlers differentiate between 404s and 410s. In this video, Matt Cutts from Google discusses this distinction. Properly differentiating between 404 and 410 errors can improve your site’s standing with Google.

Server Errors (5XX)
500 – Internal Server Error

The 500 Internal Server Error is a common server-side error that arises from an unexpected issue preventing the server from fulfilling a request. As a catch-all error, it’s used when other specific 5XX server-side errors don’t apply.

500 Internal Server Error Page500 Internal Server Error Page

Even though the issue is server-related, you can try actions like reloading the page, clearing your browser’s cache, or deleting cookies and restarting the browser to resolve it. If the problem persists, inform the webmaster. If you encounter this error on your own site, check for a permission error, a corrupt .htaccess file, or a low memory limit. WordPress users should also consider a problematic third-party plugin and deactivate plugins one at a time to identify the issue.

502 – Bad Gateway

The 502 error occurs due to communication issues between two servers. It happens when the client connects to a server acting as a gateway or proxy, which then tries to access an upstream server for additional services. An example is an Apache server accessed by a proxy server, or a large ISP’s name server accessed by a local name server.

Encountering a Bad Gateway error means the server received an invalid response from an upstream server.

502 Bad Gateway Error Page502 Bad Gateway Error Page

This error typically indicates a disagreement in data exchange protocols between servers rather than an outright failure of the upstream server. Contact your hosting provider if you see a 502 error on your site.

503 – Service Temporarily Unavailable

The 503 Service Temporarily Unavailable error appears during server overloads or maintenance periods, indicating the server is currently unavailable but the condition is temporary.

503 Service Temporarily Unavailable Page503 Service Temporarily Unavailable Page

Website owners should be knowledgeable about the 503 status to manage scheduled maintenance properly, as improper handling can affect the site’s search engine ranking. For guidance, refer to tutorials on Yoast’s SEO blog or moz.com.

504 – Gateway Time-Out

The 504 Gateway Time-Out error is another server-server communication issue, similar to the 502 error. It occurs when a lower-level server doesn’t receive a timely response from an upstream server it’s trying to access.

This time-out issue, akin to the 408 Request Time-Out error between client and server, usually signals slow communication between the two servers or the possibility that the upstream server is down.

504 Gateway Time-Out Error Page504 Gateway Time-Out Error Page

As 504 errors involve network issues beyond typical user control, addressing them requires access to the network’s backend. In many cases, simply refreshing the page after a few minutes can resolve the issue, assuming the service providers are actively working on the problem.

Wrapping Up

In conclusion, understanding HTTP status codes is more than a technical necessity; it’s an essential part of creating a seamless online experience for both website owners and visitors. From the common 404 Not Found to the more complex 500 Internal Server Error, each code offers valuable insights into the health and functionality of a website. By effectively recognizing and addressing these errors, website administrators can significantly enhance site performance, improve user satisfaction, and maintain optimal SEO rankings.

Remember, each error code is an opportunity to troubleshoot, improve, and evolve your website. Armed with the knowledge from this guide, you’re now better equipped to handle these challenges and ensure that your site remains accessible, efficient, and user-friendly. Let’s embrace these codes not as hurdles, but as stepping stones towards a more robust and resilient web presence.

10 Best Dropshipping Websites Examples in 2024

Original Source: https://ecommerce-platforms.com/articles/best-dropshipping-websites-example-design

If you are contemplating setting up your first ecommerce store but are not sure what line of business is best for you, dropshipping is one of the best places to start.

Dropshipping stores have a low barrier for entry, require minimal capital and leave all the logisitcs to the dropshipping supplier.

Your sole role is building the website, optimizing for search engines (i.e. SEO), finding customers, facilitating the order and providing post-purchase customer support.

But while dropshipping rides on a relatively simple online business model, not every dropshipping store survives or thrives.

If you are going to succeed, learning from those that have made it can significantly increase your odds. And success revolves around the website. Dropshipping is dependent on the quality and features of the site it runs on.

We take a look at the best dropshipping store examples and the attributes that make each of them stand out from their peers.

Note that while Shopify is the most popular ecommerce platform among the best dropshippping stores, you can create a successful website on other platforms too.

Best Dropshipping Website Example Designs

1. Warmly Décor

Product Type: Home Decor

Warmly Décor claims to offer high quality décor products at as much as 80% off retail prices by shipping products from various factories across the world. The main product categories are furniture, bathroom and lighting.

Key Strengths

Simple color theme – With black text, a white background and a small navigation menu, Warmly Décor maintains a clean and uncluttered feel.

Under $200 page – For shoppers looking for lower priced items, Warmly Décor has a $200 and below page.

Real-time purchase notifications – A message pops-up at the bottom of the screen each time someone around the world buys from Warmly Décor. It shows the first name of the person as well as the specific product they ordered. This marketing technique rides on a basic trait of human behavior – people are naturally drawn to things that other people like.

Automatic currency converter – Items are automatically listed in users’ local currency based on IP address.

2. Babybub

Product Type: Maternity Products

Babybub sells multiple dropshipping products for pregnant and nursing women such as maternity leggings, maternity belts, sleep masks, wearable breast pumps and compression travel cases. However, the store’s flagship and best-selling product is the maternity pillow as well as its full body attachment.

Key Strengths

Focus on best-selling products – Babybub’s home page is effectively dedicated to the maternity pillow. While product diversification is good risk management, prioritizing the home page’s real estate to a product with tried-and-tested demand can be a great way to maintain and grow sales.

Discount Pop-Up – Visitors to the website get an offer for a 10% discount on their first order if they sign up to Babybub’s mailing list. By providing an incentive to sign up, Babybub aims to not just increase sales but also expand its marketing reach. Email marketing remains one of the lowest cost digital marketing channels.

‘Maternity’ in logo – The store has a catchy name but one that might be a little confusing for visitors expecting to find infant-focused products. To clarify its target market, the logo includes the word ‘maternity’ to show who its primary audience is.

3. Be Activewear

Product Type: Clothing

Be Activewear is an Australia-based fashion online store that sells sportswear products representing more than 60 Australian brands. While most items primarily target teen and adult women of different body sizes, the store also has products for men and children.

Key Strengths

Minimizable discount offer – When visitors land on a Be Activewear page, they are presented with a pop-up offering a 10% discount on the first purchase if they opt into the mailing list. If one chooses to close this pop-up, it is minimized to the left corner of the screen. This makes it always accessible anytime the user decides they would like to opt in.

Free shipping clarity – Many of the best Shopify dropshipping stores claim to offer free shipping but fail to indicate the conditions under which this is available. The end result is shopper disappointment and a rapidly growing number of abandoned shopping carts. Be Activewear states at the top of each page that free shipping is only available for orders above a specific amount and that this minimum is different for Australian orders and international orders.

Custom orders – If a customer is looking for a particular brand or products but one that isn’t available on Be Activewear, she can send an email to the store and they commit to trying to get it on board.

4. Burga

Product Type: Phone Cases

Burga is a dropshipping website that mainly sells phone cases but also other phone, laptop and tech accessories. Founded in Lithuania in 2016, it attracts hundreds of thousands of visitors per month and ships worldwide.

Key Strengths

Frozen notification bar – Burga has a sale, discount, and shipping offers notification bar at the start of the page. It remains visible even when a visitor scrolls down further along the page.

5. Fashion Nova

Product Type: Clothing

Fashion Nova is one of the largest dropshipping stores in the world. Apart from the millions of visitors to its ecommerce store, the company also has a couple of physical stores.

Key Strengths

6. Haus

Product Type: Furniture

Products are sourced from major European and international design brands as well as smaller and independent manufacturers.

Key Strengths

Simple layout – The website has a simple layout that features cool page colors, gentle fonts, a brief navigation menu as well as a large hero image above-the-fold.

Physical Shop – For shoppers that may not be comfortable ordering furniture online, Haus provides the option of visiting their shop. While the cost of setting up a physical store may be prohibitive for most brand new ecommerce stores, it can serve as a useful source of foot traffic if the website’s traffic and revenue’s growth demands it.

Pay in installments – For higher value items that are not currently in stock, customers can pay 50% when they place the order and 50% when the item is restocked and available for delivery.

Key Strengths

Product diversity – Inspire Uplift has an expansive range of products. From a business perspective, this is vital for the diversification of income streams.

Customer reviews – The store displays the current number of customer reviews via a link at the top of each page. There are currently more than 70,000 buyer reviews which provide important social proof.

24/7 customer support – Inspire Uplift provides 24/7 customer support through a live chat service and email. Unlike a lot of dropshipping stores, the company can also be reached via phone and has also indicated its physical address in Miami, Florida. Such accessibility inspires confidence among potential customers that they are buying from an established store.

Social media diversification – Many dropshipping stores focus their social media marketing strategy on the one social media network they have found greatest success. Consistent with the store’s diversification strategy, Inspire Uplift has a large social media presence on four major platforms – 6 million Facebook followers, 3.8 million on Pinterest, 270,000 on YouTube and 72,000 on Instagram. Only on Twitter and TikTok does the store have a small following but the accounts remain active, likely as an effort to steadily grow reach over time.

8. Materiol

Product Type: Labelers, Organizers and DIY

Materiol deals in labelers, organizers and do-it-yourself (DIY) equipment. As with a lot of everyday items, most of the products are sourced from China.

Key Strengths

Simple – Materiol has a simple layout. The home page has a single hero image that indicates the three product categories the store specializes in.

GIFs – For some products, the store uses GIFs as the thumbnail image. That not only draws user attention but allows the dropshipping site to quickly demonstrate a product’s features and capabilities.

Shop by brand – Materiol has dedicated pages for the brands available on the website. Users who want to avoid going through all the products in a particular category can go straight to the brand they are most interested in.

9. Notebook Therapy

Instagram reach – Instagram has one of the highest engagement rates among social media platforms. Each post on Notebook Therapy’s Instagram account draws thousands of likes thereby being a steady source of low cost leads.

Automatic price currency conversion – The website detects the visitor’s location and automatically displays prices in local currency. This takes away the need for mental or manual arithmetic when determining the local currency equivalent of dollar-quoted pricing.

$50 coupon – Through an on-page pop-up as well as on the main navigation menu, visitors are encouraged to opt into Notebook Therapy’s mailing list to win a $50 gift card.

10. Palo

Product Type: Gadgets and Gifts

Palo sells mostly small trending gadgets and gifts.

Key Strengths

Minimalist theme – The store has a simple black and white look and feel accentuated by the livelier colors on the home page’s hero image.

Orderly product descriptions – Product pages are simple, intuitive, organized and tidy. Product features are described in bulleted paragraphs and are accompanied by high quality product images.

Automatic currency converter – Items are automatically listed in users’ local currency based on IP address.

Free shipping – Palo provides free shipping for the majority of items on the website with no requirement for a minimum order amount.

Transparency on long shipping times – The store is upfront about sourcing its products from factories around the world resulting in longer wait times than for a standard ecommerce business.

11. Amazingly Cat

Product Type: Cat Toys

Founded in 2016, Amazingly Cat offers unique cat toys that are not typically available in major retail stores.

Key Strengths:

Personality quiz – To make sure cat owners are getting the right toy for their cat, Amazingly Cat has a cat personality quiz. Owners respond to a set of questions that assess the cat’s age, temperament, activity, likes and dislikes. The store then offers recommendations on what toys are likely to be most suitable.

Social media – Amazingly Cat does a good job of leveraging free traffic from its Facebook page. By regularly posting products and content to its more than 1 million followers, the store can generate a steady flow of leads from a pool of fans that are interested in cats and cat toys. It has a smaller but significant presence of more than 60,000 followers on Instagram. This is substantial given Instagram has a higher engagement rate than Facebook.

Blog – The store has an active blog containing regular posts sharing important insights on cats. It has useful tidbits for everyone from first-time cat owners to more seasoned pet owners.

Wrapping Up

Dropshipping is a cut-throat industry. From the get-go, your dropshipping store is in a battle for eyeballs and conversions against dozens or hundreds of entrepreneurs selling identical products.

It is easy for one to sink into insignificance amidst this sea of competitors.

Despite the intensity of competition, the dropshipping stores covered here have soared above the waves and maintained an edge over their rivals.

That said, it is important to note that replicating a successful dropshipping store’s website design and business strategy is unlikely to work.

Instead, assess the strengths of each website within the context of your dropshipping business goals then adopt what is most relevant to your business goals. Further, work with reliable dropshippers only that have a stellar reputaiton for delivering on orders.

A Guide To Designing For Older Adults

Original Source: https://smashingmagazine.com/2024/02/guide-designing-older-adults/

Today, one billion people are 60 years or older. That’s 12% of the entire world population, and the age group is growing faster than any other group. Yet, online, the needs of older adults are often overlooked or omitted. So what do we need to consider to make our designs more inclusive for older adults? Well, let’s take a closer look.

This article is part of our ongoing series on design patterns. It’s also a part of the video library on Smart Interface Design Patterns 🍣 and is available in the live UX training as well.

Make Users Feel Independent And Competent

When designing for older adults, we shouldn’t make our design decisions based on stereotypes or assumptions that are often not true at all. Don’t assume that older adults struggle to use digital. Most users are healthy, active, and have a solid income.

They might use the web differently than younger users, but that doesn’t mean we need to design a “barebones” version for them. What we need is a reliable, inclusive digital experience that helps everyone feel independent and competent.

Good accessibility is good for everyone. To make it happen, we need to bring older adults into our design process and find out what their needs are. This doesn’t only benefit the older audience but improves the overall UX — for everyone.

One Task At A Time and Error Messages

When designing for older users, keep in mind that there are significant differences in age groups 60–65, 65–70, 70–75, and so on, so explore design decisions for each group individually.

Older adults often read and analyze every word (so-called Stroop effect), so give them enough time to achieve a task, as well as control the process. So avoid disappearing messages so that users can close them themselves when they are ready or present only 1 question at a time in a form.

Older adults also often struggle with precise movements, so avoid long, fine drag gestures and precision. If a user performs an action, they didn’t mean to and runs into an error, be sure your error messages are helpful and forgiving, as older adults often view error messages as a personal failure.

As Peter Sylwester has suggested, sensory reaction times peak at about the age of 24 and then degrade slowly as we age. Most humans maintain fine motor skills and decent reaction times well into old age. Therefore, error messages and small updates and prompts should almost always be a consideration. One good way to facilitate reaction time is to keep errors and prompts close to the center of attention.

As always, when it comes to accessibility, watch out for contrast. Particularly, shades of blue/purple and yellow/green are often difficult to distinguish. When using icons, it is also a good idea to add descriptive labels to ensure everyone can make sense of them, no matter their vision.

Guidelines For Designing For Older Adults

Avoid disappearing messages: let users close them.
Avoid long, fine drag gestures and precision.
Avoid floating labels and use static field labels instead.
Don’t rely on icons alone: add descriptive labels.
Ask for explicit confirmation for destructive actions.
Add a “Back” link in addition to the browser’s “Back” button.
In forms, present one question or one topic per screen.
Use sufficient contrast (particularly shades of blue/purple and yellow/green can be hard to distinguish).
Make error messages helpful and forgiving.

Wrapping Up

We should be careful not to make our design decisions based on assumptions that are often not true at all. We don’t need a “barebones” version for older users. We need a reliable, inclusive product that helps people of all groups feel independent and competent.

Bring older adults in your design process to find out what their specific needs are. It’s not just better for that specific target audience — good accessibility is better for everyone. And huge kudos to wonderful people contributing to a topic that is often forgotten and overlooked.
