Chronology of SEO Processes
One of the hazards of search engine optimization is that it is a moving target. Some strategies and tactics that worked in the past, don’t work as well now, or have generally become devalued. Most have changed in relative importance in some way, whether significantly or less so.
Think of “keyword stuffing” which garnered search engine favor a long time ago. That expedient of placing lots of relevant keywords on a page can actually work against the purpose of making a page more attractive to search engines and users.
OK, that’s an obvious example, but what else has changed over the years?
Rand Fishkin at SEOmoz has created and published some graphs of his perspective on the relative value of different SEO processes, over time.
The two graphs depicts the relative value of user-focused SEO tactics as well as search-engine-focused tactics from 1997-2009.
