Find the Google Ads spend that brought nothing back
Connect your Google Ads account and the free check-up lists the search partner sites and placements that took your budget and returned no conversions, plus the spend on people outside the area you target, with the dollar figure beside each. Add the ClickLens tag and every form-fill is graded as well, so fake leads stop teaching Smart Bidding who to bid for.
The click fraud problem
Google's built-in invalid click detection catches some automated fraud, but sophisticated bots, click farms, and competitor attacks slip through.

Invalid clicks come from multiple sources: competitor click fraud designed to exhaust your daily budget, bot networks running automated click campaigns, click farms hired to inflate metrics, and scrapers that trigger ad impressions without real interest. Google refunds some of these, but the bots that behave like people survive its filter and reach your spend.
How ClickLens protects your Google Ads
The check-up needs only the Google Ads connection. Add the tag and the rest runs on a schedule.
Install the tag
Add a single JavaScript snippet to your landing pages. Works with any website, CMS, or tag manager.
Measure every visit
Every visit is measured on 40+ behavioural signals: how the mouse moves, whether the device fingerprint holds together, whether automation markers are present.
Score clicks and conversions
Each visit gets a human, suspect or bot verdict while it is still on the page, and any conversion it reports is graded on how it was produced and the journey that led to it.
Sync exclusions
Fraudulent IPs and placements are synced to your Google Ads exclusion lists on a recurring schedule, so they stop being served your ads on the next sync.
Protect Smart Bidding from polluted conversions
Target CPA, Target ROAS and Maximise Conversions all work the same way: they buy more of whatever converts. A fake form fill or sign-up reads as a win, so the bidder steers budget toward the source that produced it. Blocking the IP afterwards cannot undo that, because the conversion has already fired and trained the algorithm.
ClickLens grades each conversion on its provenance — the timing and structure of the submit, never the field contents — and on whether the journey to it makes sense, then resolves it to pass, downweight or retract. Google has the strongest write-back path of any platform: a live OAuth connection plus the documented click-id adjustment API, so a retracted or restated conversion is corrected in your account keyed by gclid. That write-back is in measured rollout: every gate runs in shadow mode first, where the dashboard shows the adjustment it would make, and verdicts change platform data only after the false-positive rate has been measured on live traffic against a 10% holdout.
You can also send Google only the leads that pass, as a conversion action of their own, so bidding learns from the people who filled in your form and never hears about the rest.

Features for Google Ads advertisers
Automatic IP exclusion sync
Connect your Google Ads account and ClickLens pushes bot IPs to your campaign-level IP exclusion lists on a recurring schedule. Once a flagged IP is excluded, your ads stop being served to it.
Waste calculator
See how much of your Google Ads budget went to bots, in dollars, by campaign, ad group and keyword.
Real-time scoring
Sessions are scored in real time, so you don't have to wait for daily reports or retroactive analysis to see a verdict. Flagged IPs and placements then sync to your exclusion lists on a recurring schedule.
Transparent scoring
Every session shows a full scoring breakdown across automation (25%), fingerprint (20%), behaviour (25%), network (15%), and context (15%). Open any session to see which signals produced the verdict, and dispute it if you disagree.
Traffic source analysis
See which UTM sources, campaigns, and keywords are sending the most bot traffic. Pause the placements that send bots and move the budget to the ones that send buyers.
Your other ad platforms
The same tag scores visits from Meta, Microsoft and TikTok ads, so you can see what those clicks were worth too. Exclusion sync and fake-lead upload work on Google Ads only.
