Creating A Clíck Fraud Action Plan For Your PPC Campaign

By John McElborough

OK so you’ve read or heard enough to make you concerned about clíck fraud. In a 2006 survey of 1,400 search marketers in the U.S under 50% of the group had plans to monitor clíck fraud across their campaign in the coming 6 months (MarketingSherpa) so by creating an action plan now you will already be in the minority of mindful and risk conscious PPC marketers. Your PPC clíck fraud action plan will be tailored to your own campaign budget and your analysis of the risk level involved. Here’s a guideline.

Allocate a Budget

This should be relative to your campaign ROI. If you’re spending £1000/ month (roughly $2,000 USD) and you measure your campaign ROI at 125% you’re not going to want to spend £250/ month (roughly $500 USD) monitoring clíck fraud. If you haven’t noticed the effects of clíck fraud already, chances are your invalid clíck level will be 5% or lower so as a general rule you won’t want to regularly invest more than 5% of your estimated gross campaign profít back into clíck fraud detection. (The % effort for clíck fraud detection should be taken from your profít and not from your campaign budget as this is supplementary work. If you detect zero invalid clicks, you will still have spent the same total budget.)

Assign Responsibility

Who will be responsible for monitoring invalid clicks across your campaign? If your PPC account is managed internally by your marketing team this may be another role for them in their regular account maintenance duties. If you use an agency to manage your PPC, they may take responsibility for this either included in your package or at an additional cost. Ask your agency what their policy and action plan is for clíck fraud detection. If your campaign budget exceeds around £5k a month ($10,200 USD), you may want to consider using a clíck fraud vendor (a specialist agency dealing with clíck fraud) these have sprung up across the U.S and are starting to appear in the UK too (I will review UK vendors in future posts or there may be ads on this page).

Decide on a Timescale

You may be losing monëy to clíck fraud on your PPC campaigns right now. Then again chances are if you haven’t noticed you may not be. The major search engines do monitor clíck fraud or invalid clicks and should alert you to this but none the less, if you have a largër PPC budget, you should be doing your own monitoring right now. Calculate how much you could be losing based on your total spend and a ball park figure of 5% invalid clicks due to clíck fraud. Then work out how many hours you should be assigning to this. If you calculate you could be wasting up to £1000/ month and you value your time at £100/hour then any time under 10 hours a month spent on clíck fraud detection could make it a profitable exercise. Set a date for review, say at 3 months and 6 months and report back to all parties responsible for the campaign to analyse the estimated impact of clíck fraud on your PPC budget. If you have found nothing suspicious after 3 months, put clíck fraud detection work on hold for 3 months and do another audit.

Make it Policy

Make clíck fraud detection part of your PPC campaign policy and procedure. Make it a subject at planning meetings and try to fit monitoring into your day to day account maintenance.

Doing It

A plan is worth nothing without effective implementation. Clíck fraud can be a complex area but there are some simple signs to look out for. Here’s a summary of the top signs of clíck fraud:

1. Clíck through rate (CTR). Monitor your CTR’s historically and look for sudden, sharp % increases. Sometimes these may be explainable i.e. the seasonal nature of your AdWords campaign, but it could also indicate these clicks are invalid or fraudulent.

2. Sudden drops in conversion rates. If your campaigns usually convert at a steady 3% month in month out and this suddenly drops for no apparent business reason, it could indicate clíck fraud as invalid clicks will rarely go through your site any further than the destination URL landing page.

3. Faster than usual daily spend. Look at your hourly data and get a feel for when in the day your budget usually runs low and your ads stop showing. If on 1 day or a run of days your budget runs out sooner than usual, it could be a sign of clíck fraud.

4. Keyword stat variations. Look at very similar keywords that usually attract similar CTR’s. A spike in 1 keyword and not the other is a tell-tell sign of clíck fraud.

5. Suspicious IP addresses. Your web logs or Google Analytics will give you a record of the IP addresses of every visitor to your site. Although not all ISP’s provide their customers with unique IP addresses, above average page impressions for a certain IP address is often the best way of spotting clíck fraud and Google may ask you for this information when conducting a clíck fraud investigation on your behalf. Google Analytics is a really useful way of matching IP addresses to PPC clicks.

6. High traffíc levels from unusual locations. Again your web stats or Analytics will help you here. Look at the geographic location of your PPC clicks. If you run an international campaign, look for high levels from countries you don’t usually deal with or where a different language is spoken. If you’re UK based, look for unusually high clíck densities coming from particular locations even though your campaign or product is not regionally based.

7. Remember to look at CTR’s and conversion rates separately for search clicks and content network clicks otherwise the overall data could be skewed.

Above all remember it is the smallest percentage of pay per clíck advertisers who ever see serious effects from clíck fraud so be cautious but don’t sacrifice the benefits of a well managed pay per clíck campaign for irrational concerns.
