I was checking up on the list of "Allowed Sites" in my AdSense account and noticed a list of "Unauthorized Sites" had displayed my ads. They were all just IP addresses: 209.85.175.104 209.85.141.104 64.233.179.104 209.85.215.104 It appears that all of those sites are Google. I assume that the ads are being displayed when one of my sites comes up in the Google Image search. (Could there be other reasons?) I'm wondering if it's useful to add those IPs to my Allowed Sites list. Are there any possible downsides to adding them?
I think without a proper reason, you should not add any sites to your 'Allowed Sites' as it may invite danger. After all you are not get your ads displayed from google. are you? So its better not to add them.
Those appear becuase for some or another someone viewed your website with the Google Cache. Yes I do add googles IP's ..
adding googles ip address is as much risk as someone that doesn't use "Allowed Sites". any site that iframes your site would show up in that list,so yeah,add googles ip address to allowed sites.
I only add my own sites, not others such as Google's IPs. I know that I'm missing out on a little traffic, but from how often I see them in my webstats, a quick glance tells me it's less than 0.5%. It could be abused by a competitor or malicious individual who only knew of one site which your ads had been placed on (before you removed them for whatever reason), and wanted to have a chance to click bomb you. It could also be used by someone to display and count your ads on a site that is not on your allowed list. I'm not going to explain how that would work, for certain reasons. Anyway, I don't remember for sure, but do ads showing in cached pages on Google show up strange ad results? I know Yahoo's ads do that, like when viewing a page with them on the Internet Archive, the ads will usually show up for tech-type stuff, no matter what the content is (probably due to the page that opens them). There are probably some other minor reasons, but in my opinion, it doesn't seem worthwhile to have them allowed on pages like that.
You only get paid for ads that appear on your "Approved URLs" list. So, if someone clicks on your ads that appear on a non-approved URL, you don't get paid. Because you have told Google that ads on these pages are NOT legitimate (not authorized by you). You can't have it both ways. On the one hand, you are protected for approved sites. On the other, you receive NO MONEY from clicks on unauthorized pages, because you have told Google that these ads are not placed there by you. You can't say, "These ads were not placed by me", and still get paid for them! Even if you wanted to add the IPs, there are potentially hundreds of them. This would be a nightmare. Here are mine for last week. . .209.85.215.104 64.233.179.104 209.85.141.104 209.85.175.104 74.125.39.104 209.85.171.104 www.windowslivetranslator.com cache.search.yahoo-ht2.akadns.net 203.84.199.31 10.128.135.139 10.128.135.131 10.128.135.134 10.128.135.143 images.google.com.bd 10.128.135.144 10.128.135.142 . .
I hadn't thought of that. I wonder why someone would view my sites through the cache. After I posted here, I actually went into my stats to see how much traffic I was getting from Google (other than the organic search results, of course), and it's less than 1%, so I'm probably not missing much by excluding those IPs. I'm pretty sure that's how it works. Yes, that's true. I wonder, though, if there can be a danger of invalid clicks or other ToS violations if ads with your Adsense code are displayed on other sites.
