Ok, I have a site, PR4 and over an year old, it usually takes about 5-10k uniques from google on matchdays (soccer related), and now, from this Friday, it stopped getting new traffic. It only receives traffic for older pages, even though new pages are indexed, It just stopped being relevant for new posts. Never done any blackhat, in fact there are a few LE with other good soccer sites (maybe that's an issue - poor links). So I have no ideea what happened, only that my adsense earning have gone very low. Anyone have the same experience?
before your visitor decrease, your site has good SERP in google maybe page 1 or 2?? have you check your keyword on google??maybe your page in sandbox, try give backlink to those page from your older page.
If you have Adsense on more than one site, and if any of those sites drop below 3% CTR, all of your sites will suffer. To fix it, find the site with the bad CTR, remove the Adsense and your other sites should go back up to normal. Make changes to the bad site and you can try to put the Adsense back on. Zeek
It may be due to some of your sold links. I would be a bit worried as it may eventually affect your old pages. Ensure you only sell links to related sites and try to integrate the links into your content.
