Search Engine Algorithm factors/signals

A great reference for search engine algorithm factors/signals. I have found many of these to apply/work well for me.

Every two years, Moz surveys the opinions of dozens of the world’s brightest search marketers and runs correlation studies to better understand the workings of search engine algorithms. We gather this data to gain insight into the factors that may help—or hurt—a website’s visibility in search engines. Note that these factors are not “proof” of what search engines use to rank websites, but simply show the characteristics of web pages that tend to rank higher.

This year, Moz surveyed over 120 leading search marketers who provided expert opinions on over 80 ranking factors.

Below we present the results of Moz 2013 Correlation Study.

  1. I am extremely impressed with your writing skills and also with the layout on your blog. Is this a paid theme or did you customize it yourself? Either way keep up the nice quality writing, it’s rare to see a nice blog like this one these days.. :)

  2. Wow, so # of Google +1′s is important now?

  3. Truly the factors any SEO expert must take into consideration. Great list!

  4. Was looking for a good list of things to watch out for. I appreciate that this particular list sorts out factors by importance.

  5. How valid is this in 2014?
