I recently optimised some existing pages on a clientís website, within two days this new content had been spidered and indexed and they had a number of top 10 results in Google. Two days later many of the rankings have dropped to the mid twenties and some have gone out of the top 100.
I know that new pages are usually given a rankings boost when they are first spidered and indexed but I didnít realize this affected existing pages that have had new content added to them.
Can this be a hilltop influence?
Has anyone had any experience of this type of problem with existing pages before?

That could be the key! What did you do beyond adding text? Fresh content can get a boost on some sites and as you say, new pages nearly always get an initial boost. However, your comment about optimising may have not worked. Too much bold, H1 or perhaps some dodgy links out may have harmed you. Hilltop is all about off site stuff, so unlikely to have had such a quick effect.
The pages didn't really have any content before, Iíve added approximately 200 words to most of the pages. Each page has got one H1 heading containing the main key phrase for that page and the title contains the main key phrase plus the name of the company.
I have increased the number of internal links and changed the link text on some of them to get some more relevant link text in. It doesnít seem as though any of the pages are over-optimised as a few of them have maintained their top ten rankings.
This could be effecting the pr flow throughout the site. The net result could be that with more drain from the home page of pr, less is being sent to key pages. The toolbar will not be showing any difference, but behind the scenes this could be a problem. Focusing pr on important pages may be more important than tons of anchor text per page.
