what is the technical reason for Ehow going up
Some might say eHow is a winner because they use AdSense. But many other sites that have been demoted use AdSense so that theory does not stand up.
Could it be their inbound links? Tthe articles are written in a how-to format which may create better context for the inbound links. Just my guess.
The articles are not always written by experts, they are generally written by writers. But because they are how-to articles, those doing the linking may not be the best judges of authority but they do so as a vote for the quality of the content
and they get the link.
Is this a flaw in the new algo if those citing the page aren't necessarily the best judges of quality?
So why did HubPages lose but eHow didn't? HubPages content is not generally how-to in nature. They're about topics. eHow pages are about how to do things, which potentially set up different kinds of backlink contexts. Could the context of the backlinks be playing a part in deciding winners and losers?
Why was hubpages targeted? I tried to get a feel for how community sites and pages link to each. According to Yahoo, more phpbb sites link to it than do ehow. More wordpress sites link to hubpages over ehow. More vBulletin sites link to hubpages, too. I ran different searches in Yahoo to find differences between the two sites but HubPages seems to beat out ehow in all the backlink searches, even for backlinks modified by the phrases "Great Article" or "Check this out".
So I circled back to article topics. One interesting difference where eHow did better is in a backlink search for sites linking to hubpages and ehow. Backlinks to ehow with the words "SEO" anywhere on the page were around 90,000. Backlinks to HubPages with the words "SEO" anywhere on the page were over 350,000 links.
