List Of Search Engine Ranking Factors
Everton | Apr 28, 2007 | View Comments
In what must be one of the most useful posts of the year for any aspiring blogger, Carsten from Search Engine Journal has pulled together a simplified version of the monster Search Engine Ranking Factors document, which contained the opinions of 37 SEO experts. I’ve pasted the full table below.
I’d really like to get a discussion going with my own readers as to whether we agree with the top 27 factors, and what a blogger can actually do to influence external factors like getting other bloggers to link to their posts using the right anchor text. For instance, ever since I saw how important using the right anchor text was whenever I’ve linked out to a site, I’ve tried to use the best anchor text possible to try and help the site I’m linking to.
It was also interesting to see that there wasn’t a consensus on whether selling links is a good or bad move for a site.
