OK, well not all the time. But I have noticed that sometimes on some of my pages it is the exact same ads I saw yesterday. Also if I refresh the site it is the same ads yet again. Or sometimes two ads will be the same as before and one will be different. The best page to look at for this is my forums since everything else is being redone. The forums can be seen at http://www.journeyoftheanimals.com/petchat/index.php I only have like 2 or 3 advertisers blocked so I know that is not the problem. Can people that pay for these ads request that only show up on sites that have a certain amount of traffic. If they can then that would completely explain this. Thank you for your replies Adam Burgi
Build more backlinks. The more the bot comes to your site, the better ads you'll see. Stop checking for ads, just add new content all the time.
Ads are also shown by country specific. You may not see ads which are only to show some other country visitors. I sometimes see same ads always but its only to show indians, and then others see some Ads, that I have never seen.
Yes Mayank is right - what you see is not what others see. Also if you write about a variety of topics the ads will change because it seems that there may be few advertisers in your niche.
