When you perform a search with Google or Bing, one of the elements which allows a website to climb the results pages are the backlinks pointing to the site. When the links are from a similar site, which is related to the site they’ve provided a link for it tells the search engine that “even though we’re an authority, this other site is better than we are” type scenario. This is an extremely basic description of how the search engine results pages become filled with those little blue links, but Facebook search is going to try and do something a little different.
Facebook isn’t necessarily concerning itself with virtual locations, they are wanting to focus on the real world version of a page. Instead of using a similar system of backlinks however, they will be going down the route of using a like system, using your friends list as a foundation. It’s a twist on a way to determine a search results page, and it’s going to have some interesting applications moving forward with some people having hundreds and thousands of friends.
A solid description of one of the goals of Facebook search that I came across was it can be considered a multi-dimensional search results page. If you have a vacation planned for Las Vegas for example, you would need a hotel to stay at and try to plan it around the shows and events you would want to enjoy. Performing the search on Google or Bing, will return you the pages that have typically the best SEO laid out based on your search terms. From there you would do more research until you made your decision. The goal of Facebook search and using the Like idea, is that when you perform the same search within their service, you instead get a results page populated with the results based on your friends feedback. Instead of your results being based on the best optimization team, it will be based on the experiences of your friends, and if they enjoyed their visit to a particular venue.
There is a great deal of discontent already for the way that SEO works, and a lot of speculation that the methods used are gaming the search engines and breaking and bending rules to cheat to rank. The system, while built on solid principles does have it’s flaws, but it works as it is implemented. When Facebook introduces it’s method of basing their results around a like and share system, at that point I believe we will truly see what it is like to game a results page.
