Welcome to WebmasterWorld Guest from 188.8.131.52
I'm in the UK, Google.co.uk has been an almighty mess here for months for my widgets and I don't mean they are not returning my results in the SERPs, they are simply showing loads of completely irrelevant supplier results from companies that would not have a cat in hells chance of supplying
We haven't made any significant changes to the site in months, except removing a single link to an offsite page from a navigation bar from about 50% of the pages.
.. We made purely cosmetic changes. With a more modern look we saw a quick recovery.
The site I referred to above was ... dated, ..less so than the first site that was hit. .... cosmetic changes to its appearance and ... also improved navigation, which had been .. weak. This time we had to wait longer for recovery, which I hope won't be short-term!
In both cases, we made no changes to core site content, which we believe to be strong.
I just looked at my stats: 50% of G referrers come from page 5,7,9 and 10 (#52,#76,#91 and #101). Never seen visitors come from pages so "deep".
