Some domain expired with PageRank 4 or something. If buy one expired domain with PageRank 4, I want to know if the PageRank will be reset to 0 when Google update the PageRank next time. Thanks.
The pagerank will stick if you keep up the old pages, with content related to the original content. Do move quickly though, with each month that the site is down, the se's are more likely to de-index the site.
if the backlinks continue to stay, pr will not drop to zero. the key point is that backlinks stay or not
Well, no. If the content changes completely, google is likely to disregard the old links and see the site as totally new.
No! Even if the content changes but if the backlinks remains same then PR will not change I have examples to prove this!
It doesn't matter? And it's not logical either. Google knows when they found a back link to a website and if the registration date of the domain change you must have almost the same content as before to keep the old PR. If you change the content completly, there is no doubt at all that the domain has changed owner and it's the start of a new site. Even if you check your backlinks in Google Webmaster tools or thorugh Yahoo! Site Explorer it will still show the old backlinks but it will not be included when the PR is updated.
The PR stays IF the backlinks stay. Does not matter about the content. You should make sure that any important links(high PR) that pointed to an internal page point to the same address. (ie website.com/conference.html). Create an internal page that has the same address. Than make sure your site has proper internal structure so PR flows through the site (all pages are link together correctly). As noted by others I have a few sites that have kept their PR for the last two updates and the content changed once I reg'd the dropped domain. All the links had pointed to the main url (www.website.com) so it was easy to keep the PR. We're only talking PR here not SERP results for dropped domains.
no, content has nothing to do with PR mate, if the backlinks stay exactly the same then the website will keep its PR even if the content change.
Exactly, content or site theme has nothing to do with it. I've got 100s of examples to prove this, backlinks remaining is what counts. I've had PR 4 & 5 domains i bought and never got around to putting anything on them.. 6 months and two Pagerank updates later and they have retained their PR with a nothing but a blank page. I've had PR6s and 5s, put the exact pages back on and dropped like a rock. Its all in the backlinks.
Only thing is if the site is in a different field, webmasters might drop their links to it as it may not be relevant links for their sites. Also reciprocal links might be lost when webmasters notice that your site no longer points to theirs. Most webmasters are too busy to notice though
You made me remember of my one domain. i forgotten to repurchase the domain and someone took that. the domain was of pr4.
Yes, this is clearly the case. If the Whois changes (site ownership), the Google drops the backlinks and starts them from scratch. I know because it happened to me.
well so far i know is google is member of ICANN so they can easily grab when is the domain booked, and if want to maintain the pr yes backlink is important and if possible make the site of the same theme it was before, also get few good pr back links pointing to it so that it will get benefit in next pr update. that is all i suggest cheers
