Thanks to all those posting in this thread - it has been a comfort to me knowing other web masters and seo specialists are trying to solve this as well.
The 51 sites I manage and do SEO for were all hit hard.
Likely that is because over the years I have found what used to work and I kept repeating it. So what ever combination I was using with either on page SEO or link building has tripped something in Google to drop the sites. Hence all my portfolio has dropped.
Most are small, highly target sites with all unique content. Most written by my main writer, a retired Prof. from UC Berkley, so I know the quality is not an issue.
I have been experimenting with related keywords to the main keywords based on some advanced software that does social word relationship analysis for "story telling" as a beta tester and will see the results.
At first I thought the drop in the sites was a de-valuing of some of the link sources I like to use because in the past they worked well.
Anther thing I am looking at and testing is too many on topic anchor text links as opposed to top of the silo anchor text links - e.g. Computers or laptop vs. "pink apple notebook" - for that anchor text, if I am trying to rank for "pink apple notebook". The site that has maintained its #1 spot has more top of the silo anchor text links instead of the long tail anchor text links which I am trying to rank for. That is one observation. It seems like a small point but it may be very relevant. I am building new links with all top of the silo keywords now to test on one site.
Again, nice to be here and I am looking forward to making new friends here.
