Perhaps someone could shed some light on this. I've yet to be able grasp what the problem is.
I've generally had good rankings on Yahoo. For a targeted phrase "religious jewelry", one of my sites had been on page one for quite some time. For around 8 months now, the site (chainzonline) is on page 5 or completely disappears...
religious jewelry - Yahoo! Search Results
The only thing I noted is that the www is omitted from the URL. There has been a canonical 301 in place for over a year now. I should point out, that a little better than a year ago, the site was moved from one host to another and uses a different platform. I wouldn't think that should matter.
Granted, I understand that things change over time. However, years of being on page one, then suddenly falling to page 5, and sometimes completely vanishing for extended periods, has me a bit perplexed.
The most "visible" change I see is where they have dropped the www and I don't know why. If anyone has any ideas or see's what I'm missing, please let me know.
