Hi, about 4 years ago I set up a blog which overtime gained quite a lot of traffic for a particular set of keywords. It still has this traffic to this day. About 18 months ago, I set up an online store which sells products relating to this keyword. Naturally, as part of the SEO - I put backlinks on my original site which linked to my store - using those same keywords as anchor text. This seemed to do a good job, as it started sending organic search traffic to my online store pretty fast. About 8 months ago, I started using Google analytics. I added both of my sites into Analytics...the side effect being that Google would know I own both sites. About 4 months ago, I noticed that both my sites are now PR0. Could there be a connection to me adding both sites to Analytics?
This scould be the reason. If this is due to penalty, remove link exchanges and submit to re-inclusion in google webmaster tool. If not, you might lost value in your backlinks. Start building links with dofollow value especially on high PR pages. It will help you restore your PR.
Its not because analytic. Do not buy link and don't submit your link in those directories which have share same IP address. All the best.
It is the first time I heard like this. May be the inclusion of both sites in same account you informed google that you are the owner of both websites. After all if you are getting the same traffic no need to worry about PR. Traffic is money not the PR.
I am afraid that my site also may have similar problem. I am working hard currently to gain high PR. What if someone put my link in porn sites ? I am really afraid.
Does your rankings in SEs change when you saw your PR is 0? There is a possibility that the Google has an update or there is a problem with the tools you have used. Some of the webmasters today are not relying on the green bar anymore. What matters to them is the traffic and rankings.
Thanks for all the replies! Yes, my original site has a few TextLinkAds on it. Supposing this is the cause of the problem, what would you suggest I do if anything? And would Google penalize my other site for this? The other site has not ads at all on it. As I mentioned, my traffic hasn't dropped. But I am a little concerned that this may prevent me from developing my traffic.
It's not because of Google Analytics; but part of it is probably because of your interlinking, though there could be other factors as well. If your SERPs aren't affected then there's no real harm done, but if the PR really matters to you, then make the links nofollow, give it a good couple of months (like more than 3), and see if it has an effect.
