Proper Reaction to "Unusual or Suspicious Activity"

A couple of days ago, I saw my AdSense earnings shoot way up in a short time span. On investigating, I found that a small site that usually get no more than 50 to 100 page views a day was suddenly getting hundreds of visits in an inexplicable surge.

When I checked the log (saving it to my local machine if needed), I found that all, literally all, of the traffic was coming in via AOL search from one particular search phrase which brought up an image on the site, which AOL displays as a a thumbnail above the normal search results. This was a search phrase that normally brings only a few visits per month. But the traffic was coming in from all different IP addresses, different hosts, from different parts of the country, and with the normal and expected distribution of operating systems and user-agents. And the CTR on the ads was around 5% -- also perfectly within the normal range. It sure appeared to be real traffic from real people, but it was something like 1,000 times the usual amount of traffic to that site, in just 2 hours.

I panicked! I reported the unusual activity to Google, of course, using their form. (Which form, by the way, is difficult to find if you don't have it bookmarked.)

But in addition to panicking and reporting, I also suspended the site. I unsuspended the site the next day, but removed the AdSense blocks from the page that was getting all the traffic.

When I finally heard back from Google, it sounded like they were considering the traffic to be legitimate, and the clicks and earnings are still showing in my account. They told me I could put my AdSense ads back on and that they would be "monitoring" things closely. But by then, the traffic surge had dropped to a trickle. :(

Either way -- legitimate traffic or not -- I think I overreacted by suspending the site. After all, if Google found those clicks to be invalid, they could cancel out 2,000 clicks or 20,000 clicks just as easily as they can cancel out 200, couldn't they? And if the traffic and clicks were indeed legitimate, I may have just overreacted myself out of a few hundred dollars.

What should a publisher do, if anything, in addition to reporting such unusual activity to Google? Did I indeed overreact? Or did I, by taking prompt action to prevent possible click fraud, demonstrate to Google that I'm an honest publisher, and possibly make it less likely that my account might be inactivated?

You very much over-reacted. You had a great short term traffic boost that you could have got some decent earnings from and have now lost it.

I presonally don't think that you should have to constantly monitor your site for "unusal" activity. Your ad supplier should be sophisticated enougth to tell the difference between legitamate traffic and someone trying to defraud their system.

sonjay, you really need to diversify your revenue sources. Clearly, you are too reliant on AdSense.

It is not unusual for the serps to change in your favor. I have seen pages rise and fall with a change in ranking from perspective search engines. Enjoy the surge and keep working hard.

bateman_ap, thanks for verifying my gut feeling. Next time, I think I won't be so quick to disable anything. But I'll still probably report the unusual activity to Google as soon as I notice it.

Edge, you're making assumptions about my revenue based on facts not in evidence. My post said nothing about the diversity of my revenue sources. My AdSense income is a small fraction of my total revenue, which comes in from a variety of sources. However, it's a big enough chunk of revenue that I really don't want my account to be cancelled.

one particular search phrase

Just out of curiosity, not really related to AdSense itself, but did the phrase relate to something that hit the news or something similar. On one of my sites I often find spurts of relatively heavy traffic for some pretty obscure and arcane search terms. When I used to take the trouble to backtrack this stuff it usually turned out to be folks looking for answers as they did the NY Times crossword puzzle or some such. Sometimes after particularly difficult puzzles or whatever the increased traffic could last through the week.

You just never know where traffic is going to come from.

I had once also such a traffic surge. It turned out, that an actress where it happened that I had a page with a photo from here, committed suicide.

I sometimes find bizarre search terms coming to one of my sites and a few days later realise why it was being searched for. About 2 weeks before it broke in the press I was getting tonnes of searches for "Rebecca Looes". I just couldn't understand why (she had written something on my site) and then of course her Beckham story broke and I finally understood!

Not that I've been able to find out. It's a long-tail term (very long tail) and doesn't get many searches at all, as far as I can tell. I found one reference in a newspaper to an event this weekend that mentioned the search phrase and had a picture of the thing (not the pic on my site) -- but it was a smallish local event that shouldn't have drawn the kind of traffic I was suddenly seeing.

I guess it could have been a question in the NYT crossword or something like that. But nothing major that I could find anywhere online (or off) to explain the numbers I was seeing.

The sheer inexplicableness was what made me panic! Despite looking in many respects like real people, there was just no reason that I could find, and I thought it had to be some sort of distributed bot or something.

Now I regret my instinctive reaction. And I got to wondering if other AdSense publishers have experienced similar inexplicable surges, and what actions, if any, they took.

I'm still sort of hoping ASA will chime here with input from a real live Googler. :)

When I've had spikes in Adsense, I check my web logs to see if the page itself had a surge, and it always has. My web logs also tell the referring url's for any given page on any given day. Often this happens when someone bookmarks a page in a popular social bookmarking site - the numbers go up for a day or two. Once it happened, my site was chosen as the "select" site on some beta search engine. So long as there's a legitimate reason for the spike, it's OK.

Yeah, it's those things that you don't expect but do happen. I'll hang my head out here and assume that if Google sees a lot of [very long term] queries that lead people to your site, and other [long tail] or [shorter tail] queries for the same topic that lead people to other sites, it sees it basically as the ebb and flow of normal search activity.

As noted by mine, jetteroheller's and bateman_ap's posts above, sometimes the most (seemingly) bizarre search patterns can be perfectly normal.

We realise a sudden unexplained increase in traffic and click activity can alarm you.

If you notice unusual activity on your account, and believe the click activity may be invalid, you can send us the details via the Invalid Clicks Contact Form: [google.com...]

Reports submitted via this form are investigated, and we will follow up with you if we find a significant issue with your account.
