Page rank and search rank booth are different it's not necesary if you lose your page rank from PR4 to PR3 that means you also lose yoru search rank but i9t can be you need to check
Well it is inter dependent. But if you think logically it will effect because Google has looked upon your blog, right?
Not necesarily. PR and Search engine ranking are different. It is not the only thing to decide your page ranking.
Have you recently done a backlink analysis on your website? It could be quite possible that some of the links are no longer available (especially if they have a high PR juice value). As long as if you have fresh good quality content then there should not be a massive difference in SERPs
PR is different than SERPs. I do not understand why people worry about PR so much. PR does not guarantee you will appear placed high in searches and does NOT guarantee traffic. Concentrate on maintaining your SERPs. PR is simply a prestigious "title" and does not really guarantee that you have high traffic flow or are even having sale conversions.
Nobody could say that. It depends on too many factors like your competition for example. In most cases you won't see a drop in SERP for such a minor decrease of PR.
Well I have heard the same thing some people have mentioned here, that SERPs is more important than PR. I can use my own blog as an example, it is relatively new and it already appears on the first page of Google for some keywords. I think that if our friend asking the question concentrates on maintaining good, unique and high quality content on his site, continues his SEO efforts, he should not have any problems.
Might be or might not be. You might want to dig out the reason behind the PR drop though PR might not relate to SERP directly, IMO. Thanks,
Most likely "NO" if you are already consistency on link building process. If you have read threads here you would find that PR is not a site indicator anymore. That's true you have lost links when your pagerank dropped, but it does not mean it would effect your ranking. Sometimes just the PR of your inbound links are dropped but the value is not dropped.
You would know that your position in serps had changed before you knew your PageRank had. The 'toolbar' PageRank that you can see, lags several weeks, if not months, behind the PR that is actually used in the algorithm. So, if your serps hasn't already changed, it won't because of a mythical PR update.
