This showed up in the Quora queue: What else to try after unsuccessful attempt of creating 10 backlinks on +50 DA websites and no rank in Google?
Tsk, tsk. Yet another fool who got suckered into that search-engine optimization garbage. “DA” is Domain Authority, a tool created by people who felt they weren’t getting high enough Google PageRank scores; since Google no longer updates PageRank — which means that I’ll be 5 out of 10 forever — the DA guys were able to present themselves as some sort of, um, authority.
This Wikibit is pertinent:
The domain authority (also referred to as thought leadership) of a website describes its relevance for a specific subject area or industry. This relevance has a direct impact on its ranking by search engines, trying to assess domain authority through automated analytic algorithms. The relevance of domain authority on website-listing in the SERPs of search engines led to the birth of a whole industry of Black Hat SEO providers, trying to feign an increased level of domain authority. The ranking by major search engines, e.g., Google’s PageRank is agnostic of specific industry or subject areas and assesses a Website in the context of the totality of websites in the Internet. The results on the SERP page set the PageRank in the context of a specific keyword. In a less competitive subject area, even websites with a low PageRank can achieve high visibility in search engines as the highest ranked sites that match specific search words are positioned on the first positions in the SERPs.
All the time, people wander into my mailbox and ask me to throw them a link, or to accept their guest post, which inevitably results in throwing them a link. My view on all such matters is simply this: If you want to be on Google’s front page, write them a check. It’s a lot more honest than trying to game the system with these silly-ass SEO tactics.
