If you are a web designer-developer you have heard of Alexa. Alexa is in a way a premium version of Google Analytics. It also provides you with a detailed statistical data of your website.
One of the features that it had was “reviews”. You were able to review other websites that were ranked in the Alexa system. This is no secret but if you had an account with Alexa and had your domains added to your Alexa account and you ended up reviewing other websites your ranking would improve significantly. For example if I left a positive review for Bing.com and Google.com I would see my personal domains get bumped. Alexa will of course deny such a practice but it was evident that it would “help” to leave positive reviews for other domains.
The other issue is that there were services that provided for $ to leave positive reviews for your website. Of course again, that would improve your Alexa ranking even further versus if you left positive reviews yourself.
Alexa has finally decided to take “reviews” out of the equation. If you go on any website under the reviews section you will receive a message that the feature was retired.
There are of course other methods of manipulating Alexa’s rating system, I shall leave that for another article.
