More than a year ago Google tried to insert social networks. Probably, it was realized in order to moderate searching results at the expenseusers. In some time the voting buttons were removed.
Today, many SEO, IT blogs have written about that Google returned to the idea of taking the recommendations of users. In particular, there was an extension for browser Chrome, which adds to the search results link where you can complain about the incorrect page.

You can install the extension on the link.В At the time of writing the post, there were about 15 000 units.
Next, let’s see what it is: a tool for wimp out the competitors or a real opportunity to improve the issue?
As a tool to manage out the competitors the innovation, in my opinion, is no good. Why? I believe that to pay attention to their page some complaints must come. Taking into account the scale of Google, these complaints should be too much. Let’s say 1000 messages.It’s simple enough to make, if it should be messages from real people, then at today’s prices, 1000, claims will cost 30,000 rubles. But. There is in fact an opportunity for free talk about the shortcomings of the issue through the webmasters tools, in addition, the page you want to remove from SERP should be with enough flaws to remove it.
However, many of those, who had written about it, didn’t take into account that Personal Blacklist- that is how this add-in- is created, first of all, to personify searching readout for separate user, give him an opportunityto create his own black list of undesirable websites.
