At http://hollywoodnose.com I have conditional ads based on how many images there are for each page. So if there’s one image I’ll have a 468 x 60. If there’s 4 images I’ll have a 180 x 150 text ad appear after the 2nd image and a 336 x 180 appear below all 4. This goes on for 13 different conditions; depending if there’s 1 image, 2 images, 3 images, etc. Will this “annoy” the crawlers in turn hurting my page rank?
You can see what I mean http://hollywoodnose.com/TomCruiseNoseJob. Just brows random pages and you’ll see how the ad layout changes for how many images there area.
No, crawlers only hate it when you point to the exact same page from hundreds of different URLs. This happens with dropdown menus and tagging systems usually. As an aside, just try and make sure you have proper
alttext for all ads and images.
