What Click Fraud Protection Actually Costs (And What You Get)

Click fraud protection pricing is not complicated once you see the four models the whole category uses, but vendors rarely lay them out side by side because the comparison is unflattering to some of them. This piece explains each model, who it favours, and how to work out what you would actually pay over a year rather than what the pricing page implies in month one.

No specific dollar figures appear here for any vendor including us, and that is deliberate. Prices in this category change often enough that any number written into an article is wrong within a few months. Models change slowly. Numbers do not. If you want the background on what you are buying in the first place, the overview of click fraud protection covers the mechanics.

The four click fraud protection pricing models

Flat monthly fee per site. You pay a set amount to protect one domain, and more sites cost more. Predictable, easy to budget, and the model most small businesses find easiest to reason about. The weakness is that it ignores volume entirely, so a site with tiny spend pays the same as one with heavy spend at the same tier.

Tiered by ad spend. The plan you need is determined by how much you spend on ads each month, with thresholds you move between. This tracks value more closely than a flat fee, since heavier spenders have more to lose. It also means a good month in your business creates a bill increase in your software, which some people find reasonable and others find irritating.

Percentage of ad spend. A direct cut of what you spend. This is the model to think hardest about. It scales without limit, so as your campaigns grow your protection bill grows in lockstep, and it creates an odd incentive structure where the vendor benefits from you spending more rather than spending better. It can still be the right choice for a small advertiser, because the percentage of a small budget is a small number.

Per-tier site counts. Plans are defined by how many domains or ad accounts they cover, with agency tiers at the top for people managing many clients. This is the model that suits agencies and multi-location businesses best, since the cost per site falls as the count rises.

Most vendors use a blend, usually site count crossed with some spend threshold. Read the plan table for both axes, because the second one is often in smaller type.

What the price actually buys you

Across the category, the base subscription typically covers detection, automatic exclusion syncing to Google Ads, and reporting. That is the core product and it is broadly similar everywhere.

What sits outside the base plan varies, and this is where a quoted price and a real price separate. Watch for these:

• Extra ad accounts. A plan covering one site may or may not cover multiple Google Ads accounts pointing at it.
• Additional platforms. Coverage beyond Google Ads is frequently an add-on rather than included.
• Data retention. Lower tiers often keep less history, which matters when you want to compare this quarter to last.
• Seats. Agencies especially should check whether client logins or team members cost extra.
• Support level. Some vendors put faster response times behind higher tiers. If a broken sync costs you a week of wasted spend, that tier difference is not cosmetic.

How to calculate whether click fraud protection pricing makes sense

Run this before you sign anything. It takes about ten minutes with your Google Ads reporting open.

Take your average cost per click across the campaigns you plan to protect. During a trial, note how many clicks the tool blocked in the month. Multiply the two. That product is the absolute ceiling on what the tool saved you, and it is genuinely a ceiling rather than a result, because some of those blocked clicks would never have converted anyway and some would have been credited back by Google without any tool involved. The breakdown of Google's invalid click refunds explains how to find those credits on your own account so you do not pay a vendor for work Google already did.

Now compare that ceiling against twelve months of subscription, not one. If the annual cost is close to the monthly ceiling, the maths is not there. If the ceiling is several times the subscription, it probably is, even allowing for the fact that the real saving is somewhere below the ceiling.

Then do the harder check. Look at cost per conversion before and after, on the protected campaign against an unprotected control. That number does not care about anybody's definition of a blocked click, and it is the one your business actually runs on.

Contract terms that cost more than the price

The subscription is rarely the expensive part. These are.

Annual commitments framed as discounts. Two months free sounds good until you are four months into a tool that does not fit and have eight months left. If you have not run a trial, do not take the annual deal.

Auto-renewal with a short cancellation window. Some agreements require notice before renewal, and the window can be narrow. Put the date in your calendar the day you sign.

Cancellation by support ticket. If there is no cancel button, the process is designed to take time. Ask before signing how cancellation works, and keep the answer in writing.

Spend-based tiers with no downgrade path. Check that you can move down a tier as easily as you moved up. Seasonal businesses get caught by this every year.

How BlockClickFraud is structured

Our plans are organised by the number of sites you protect. The starter tier covers a single site, mid tiers cover a larger number, and agency tiers are sized for managing many client accounts under one login. We keep specific figures out of articles like this one, because a number written into an article drifts out of date.

What we will say plainly is that the model is site count rather than a percentage of your ad spend, so scaling a campaign does not scale your bill with it.

The short version

Work out which model you are being offered before you look at the number attached to it. Flat per-site pricing suits stable single-site advertisers. Spend-tiered pricing suits people whose budgets are steady. Percentage-of-spend pricing suits small budgets and punishes growth. Site-count tiers suit agencies and multi-location operators.

Then run the cost-per-click arithmetic against twelve months of fees, not one, and insist on a single-campaign trial before you commit to anything annual. A vendor confident in the product will not fight you on that.
