People seem to be totally confused about the new quality piece for Google's algo, and I wonder how 'special' the sites of those who used to rank and no longer do really are?
How many sites do you run?
How many sites do: Amazon, eBay, Twitter, FaceBook, WikiPedia, and all the other big players run? Now, again, how special is your website, really? Is it so special you only need one?
I only work on 5 right now, only run 4 of them, of the ones I run 1 is for a separate business, 1 is personal, and 2 are sites I can concentrate on basically full time, 1 of which is noindexed ... How many do you run?
Do you have the latest word press installed? It's a dime-a-dozen piece of software. Nothing special about WP ... Do you have the newest directory software on all of them? How many other people do too? How about eCommerce? Do you have the latest osCommerce or Zen Cart installed with friendly URLs? You and how many 1000s of other people?
Really, sit down and look at your site(s) and ask yourself how special it is when you compare it to the sites the 'big players' build ... Is it close? Is it really the quality of the highest caliber?
None of the sites I saw listed on Google's report a quality site wrongly demoted page were anything 'special' to the point where I thought I would really be missing out if they weren't included in the results ... Not one.
I see so many 'nothing special' sites out there I don't know what people are actually complaining about and I really wonder how honest their evaluation of their own sites is?
If you're wondering why you might not rank like you used to, imo you might do well to sit down, really look at your site, and ask yourself, what makes my site special?
Forget about other people's sites and the sites out ranking yours and trying to chase the algo for another round, and sit and ask yourself what makes your site special and then: what could I do better?
