What causes one page to rank higher than another in the search engines? I guess that’s the question every person doing SEO tries to figure out and replicate.
We’ve proven that quality backlinks to a page cause it to rank better, but is the anchor text used a cause for increased ranking or a correlation? Because none of us have access to Google’s Bing’s or any other search engine’s algorithm, we can only try different things out and observe the results.
That’s where things get tricky…
Say we observe the top 10 results for a bunch of keywords all have a keyword density percentage in a certain range. Does that density cause an increased ranking? What about:
- title tags (fairly sure it causes increased rankings)
- meta tags
- exact match domains
- country tlds
- non .com / .net / .org tlds
- text in header tags
- site load time
- text colour
- alt tags on images
The list could go on for pages. The point is, what causes higher rankings and what is just along for the ride?
To help understand correlation and causation a little better, let me present a great infographic from SEOMoz that does a better job than I ever could:
So what do you think? What have you found to cause an increase in SERP rankings and have you found anything along for the ride?
