This question is about the 'Like' button that can be put on webpages.
As I understand, search engines include involvement in social networks in their algorithms...
And I also believe there are people that use bots to click 'like' on Facebook pages, to increase the number of likes.
Are these bots also used on 'like' buttons on non-Facebook webpages, to increase the number of likes?
Can the search engines recognize when 'like' buttons were clicked by bots as opposed to by people?
And as I understand, there are also people who 'promote' (non-Facebook) web pages to groups of people, who all click 'like', in order to increase the count.
Presumably people in one of these groups will have lots of likes of the same web sites as other people in the group.
Do search engines recognize groups due to this, and does this subsequently affect the ranking of sites that have been liked by many members of a recognized group?
