Hi. I have a site with PR4 for its domain and index page and PR3/4 for other main pages. After I hire I guy to make some SEO my PR is still 4 for the domain but the index page and the other main pages is now unranked!! The SEO seem clean. Basically that guy removed all my keywords stuffed (I admit there were a bit overcrowded) into alt tags, title, description, links, and replace them with lighter/shorted versions. How is possible?
This is the reason why the pages of your website doesn't have rankings. Before you hire that SEO guy you mentioned your website have lots of keyword stuffing which is a blackhat method. So I guess that SEO guy you hired do his job well.
It was not black hat but the work of a guy (me) that knew nothing at that time about SEO. I just put all keywords I imagined in there. Anyway, they were not that dense. Plus, it worked like this for many many years. Anyway, I see now that it may be related to that massive Google PR update that happen yesterday.
On-page SEO has nothing to do with PR. PR is the result of links from other pages, mainly external pages. It is possible that your pages' relevancy has changed slightly as a result of the SEO work, but that is not likely an issue. First, if it is a cleaner better quality site, you will see improvement in SERPs and traffic over time. PR is meaningless but of course we all want some. /*tom*/
Since I don't know what kind of things have been done by your SEO guy, I guess he has made your site got penalized by Google. You need a reliable freenlance SEO for you.
PR dropped ? and how about your SERP ? If your ranking is still unaffected then you are fine. I don't give much weight about PR , it's really nothing.
I don't think that the SEO guy is responsible. Such things happen and from OP's description the SEO guy is doing some keyword cleaning and description targeting.
i have also faced that problem earlier but don't be panic. Next time, when google revised PR you got same PR .Don't fire your SEO he is doing well.
You can't have PageRank for a domain - pages get PageRank, not sites. It sounds like what you mean is your homepage, but that you have another version of your homepage which is homepage.com/index. This is a problem in itself, and you need to redirect or use the canonical tag to resolve it. I can't see how what the seo-er did would lose you PageRank, and the question you really need to address is - have you lost position in serps and/or traffic? Bearing in mind that any major change may cause a temporary loss, but that should be regained and improved on in a very short period of time.
Any change in the traffic from search engine? Any keyword dropping off? This is the more important issue, not the page rank.
