“I found the article useful, but second guessing google seems as impossible as ever!
”
It is, but when you start to filter in information from different people and websites, you can start to paint a picture of what has changed, or what we need to do.
Obviously it would be a lot easier if Google just told us, and if your site got penalised you got told why, so you could fix and resubmit!
Suppose it keeps things interesting
Can't see this approach working in any other industry though....
Imagine it, HMRC are fining your company and sending you to prison, but we won't tell you why, or what policy we've changed.
