using AdSense across multiple servers

[Roadkill]

My site is being slammed with traffic right now and I have had to add 2 more servers it the last 24hrs and have them load balanced.

Its a long story how I got here but. I dont have access to my stats right now but my tech guy tells me that the site is being slammed with traffic (due to a plug in a major publication) but I see no difference in my adstats.

The question is .. the ad code should make sure that I am getting credit for any clicks even across the other servers even though they are not the same IP. Right? Is there anything that I need to do in this sitution for adsense to function properly?

No. You have the code on the pages, not on the server.

Very strange that you don't see any change in your AdSense stats. Very very strange. You're sure you haven't been hacked?

Anyway the only catch I can see is that if the load balancing results in users seeing different URLs, then Google will have to re-spider everything on the new servers in order to show relevant ads.

I'm not surprised. Seems like the bigger deal the plug is the fewer clicks you get from the visitors. Though there should be some difference. I'd think you would get more clicks even though I'd not expect your usual ctr level. Maybe the shifting of servers made a difference.

But don't be too concerned. Traffic like this is fantastic. It's great potential for being book marked, linked and recomended on forums and just friend to friend. Be thankful they managed to keep your site from going down.

it shouldn't be an issue - I am load balancing html traffic over 6-8 server IPs in different DCs and never had any google trouble in years.

About the stats - I was specifically thinking about pageviews. The clicks may or may not come depending on why people are going to the site, but if the server is getting crushed by a spike in traffic then at the least there should be vastly increased pageviews.

I am having a 10 to 20% traffic jump with no consequence what so ever on my recorded ad views or earnings, I am thinking probably the extra traffic dilutes my earnings, but the additional clicks compensates, or possibly my site was due for lower earnings on Google's scheme of things and the extra traffic evened it out.

Thanks for these replys. Its not making sense to me right now why I'm not seeing any difference in stats.

Being hacked is a possibility that I have been concerned with the last 5 days.

I have to get this controlled. because this spike is small compared to whats coming. I have interviews set up with MSNBC and CNBC next week and a couple radio interviews this week. So its going to get quite nuts. Any suggestions to prepare the site for such a spike would also be appreciated.

Several possibilities:

Getting hacked and having huge warez files being downloaded from somewhere on your server. This happened to me once, a couple of years ago.

Spammers hacking you or using an exploit of some kind to send mass email. You'd probably know about this by now.

Some kind of DOS attack.

Sometimes badly written spiders just get stuck or confused. I can think of several occasions over the past few years when I was slammed by one spider from one IP address for days. Didn't appear to be malevolent, and is pretty much remedied via the .htaccess file.

...Obviously your log files would go a long way towards explaining what's happening.

Do your adsense stats now reflect the extra traffic you've been getting?
