Hi Guys We have lost our page rank from PR3 to PR0 can you please tell what went wrong. Thanks in advance
were u involved in selling links or buying links in past ? can u give ur website URL for further review ?
You could have been involved in blackhat techniques and google found you doing this. You should not openly sell your links or any other things like this in forums. It might be so because the website you are linking to are involved in any blackhat tactics and google found you linking. There are many factors, it depends on the strategies you use to get the maximum exposure.
its bcoz of google dance going on these days...it will settle down with upcoming toolbar update but u shld worry if u hav really lost some of ur backlinks or if they hav been nofollowed...so check that 1st ne ways start concentrating on further link building and try to get backlinks from few trusted and relevant sources
Is PR the only thing you lost? Is your site still indexed and ranking well? Getting traffic as normal? These are the things that really matter. PageRank is way over rated but I like to play the pagrank game also. I like my sites having pagerank but more importantly I want traffic. I have some PR5 sites that only get 100 uniques a day and some PR0 sites that get 1000 a day and rank better on Google. PR is not as important unless you are selling links only... And if that is the case then that is your answer to your original question. Quick tip.. Onetime my pagerank dropped from pr6 to a pr3 and I removed some links from my site that were linking to some other domains that may have been causing the problem and on the next update with no other changes my pagerank went back up to PR5... So check your outgoing links and your incoming links for quality.
check your backlinks again in google. And if its still exist, maybe somethink wrong with your backlink, for example, google catch you get paid link or something and you got penalty from google. You can try to send reqonsideration request via google webmaster tool to ask about your site.
Can anyone explain me how the link exchange is useful to me in SEO? and also does it brings any fruitful results in rankings.
I don't really even care about PageRank. It's just something that fills in some space on the Google toolbar
If you have backlinks then nothing to worry. You can get it back. if it is blog. do the post regularly. this is my experience to get back PR5 from unknown by only using regular genuine post.
How would Google even know if you sell links? I think the only real way they can tell is if they send spies to places like digitalpoint and keep track records of people who sell links. How else would they know with sufficient evidence that people are selling links on their site?
