Search Engine Ranking Factors and Social Signals

Social Media ToolsThat title just rolls off the tongue, doesn’t it?

Well, this is actually a post about two other posts.  I’ll bet you can guess what they’re about if you look at the title again.

Don’t worry about it – you don’t have to guess.

Rand Fishkin, of SEOmoz fame, conducts a survey every two years to create a killer SEO resource.  So, that’s what he did this year (2011).

He collected opinions from 132 SEO’s around the world and combined their opinions with data from over 10,000 Google search results.  The end result is a really awesome resource that can help sharpen your SEO skills.

Here are a few of the highlights.

These are just a few items picked from the report.  Check out the whole report here – Search Ranking Factors.

Social Media Ranking Signals

In his report, Rand included a link to an article on social signals.

The link directed to a great article on Danny Sullivan’s site, Search Engine Land.

The article is basically about six questions that Danny submitted to Google and Bing about social signals and how they impact their search engine rankings.

The article was published in December 2010 but social media factors are only becoming more important, not only as a way to be social, but as a ranking factor for search engines.

Obviously, it’s important from an SEO perspective to understand if links carry any ranking weight, if “authority” matters on Twitter or Facebook, if Facebook “likes” help with ranking and so on and so forth.

I won’t give you any summaries on this one because it’s pretty self-explanatory if you check out the article – Social Signals.

Both are definitely worth reading.
