You've optimized creatives and targeting, but CPA still isn't improving.
And you don't have a clear explanation why.
Even after improving creatives and targeting, CPA isn't dropping as expected.
You're running out of clear next steps.
When clients ask why CPA increased, the only explanation is often "the platform algorithm."
Without data to support the real cause, it becomes difficult to give a convincing answer.
Proposing ad fraud protection can come across as,
"Was everything we've done so far ineffective?"
It's difficult to introduce a new approach without undermining past efforts or having clear proof to support the recommendation.
Correctly identify what is hurting performance, cut waste, and recover true campaign results.
Spider AF can serve as a new improvement lever for exactly that.
Spider AF includes three solutions that address invalid clicks, fraudulent leads, and on-site risk.
They can be used individually or together, depending on the needs of each account.

Detect and exclude fraudulent conversions and low-quality leads
Detect invalid inquiries and fraudulent conversions to improve optimization accuracy, lead quality, and sales efficiency. Excluding fake leads also improves CRM data quality and reduces sales workload.
Monitor and visualize external tags and scripts
Detect and monitor external tags and scripts to manage on-site risk and help maintain site safety. Automatic detection and continuous monitoring support both traffic quality and brand safety.
Each solution can be deployed individually, but combining them enables broader improvement proposals across traffic quality, conversions, and site risk.
View invalid click volume, fraud category breakdowns,
and campaign detection rates on a single screen.
Logs can be downloaded as CSV files and used directly in recurring reviews.
Demo display using sample data. Actual screens vary by account setup.
A free diagnostic report visualizes invalid click rates and estimated losses in advertiser accounts, making it ready to use in proposals.

Delivery quality is an often-overlooked optimization axis
Visualize traffic quality and uncover room for improvement. It gives you another optimization lever after creative, targeting, and landing page improvements have been exhausted, and turns it into a positive proposal for advertisers.
Objectively identify the real cause of rising CPA
Quantify invalid clicks and noisy conversions to identify the true cause of performance decline with objective data.
Show the true CPA and ROAS after the noise is excluded, and use evidence-based explanations to gain advertiser buy-in.
Make it a natural improvement proposal without undermining prior efforts
With stricter government guidance on ad quality and more sophisticated AI-driven fraud, external conditions have changed significantly. When framed as "the environment has changed, so new countermeasures are needed," it becomes a positive improvement proposal that does not dismiss prior work and is easier to explain to advertisers.
Spider AF is not just a single protection tool. It is a set of solutions that covers traffic quality, lead quality, and site risk.
Choose the combination that best matches each account's challenges.
Spider AF delivers results that are easy to explain to advertisers, from reducing invalid clicks and improving CVR and CPA to lowering brand-damage risk and filtering invalid leads.
One of its key strengths is that these results are easy to communicate to clients.

When comparing fraud prevention tools, a feature list is not enough.
What matters is whether the solution is easy to explain to advertisers, easy to use in recurring reviews, and easy to turn into ongoing improvement proposals.

|---|---|---|
| Ease of explaining to advertisers | Easy to use diagnostics, case studies, logs, and improvement stories | Tends to center on feature explanations |
| Ease of telling the improvement story | Easy to propose reallocation and better CPA / CVR / ROAS | Often stops at the cost-cutting story |
| Ease of use in recurring reviews | Easy to explain through visibility, reporting, and log disclosure | Data transparency can be limited |
| Ease of internal rollout | Easy for sales, operations, and enablement teams alike | Often limited to a narrow set of departments |

Especially when advertisers ask, "What fraud measures are in place?" or "Can these numbers be trusted?", the ease of making a proposal depends not just on whether protection exists, but on how much you can visualize.
Ad Fraud refers to bots or malicious programs inflating ad clicks, impressions, and conversions to consume budgets illegitimately. In Japan, annual damage is estimated in the tens of billions of yen, making it a serious risk for agencies because it distorts performance data and can reduce advertiser trust. Spider AF detects and removes this fraud while supporting CPA and ROAS improvement end to end.
Spider AF does not stop ad delivery. It detects and excludes invalid clicks and fraudulent placements, then reallocates budget toward valid delivery. Case studies show improvements such as a 12.7% lower CPA and a 12.0% increase in conversions after invalid clicks were excluded. Rather than reducing delivery overall, the share of valid delivery increases.
Yes. Spider AF offers a partner program for agencies, including reseller and referral models, and supports everything from advertiser proposals to implementation and operations. Reseller partners can earn 20-30%, and referral partners 10-20%, creating a clear revenue model for proposal activity.
We provide abundant materials for advertiser explanations, including free diagnostic reports, admin dashboards, detection logs, case-study collections, and proposal decks for agencies. They are ready to use in recurring reviews and improvement meetings. The free diagnostic report, in particular, includes concrete loss simulations, making it easier to support advertiser decisions.
Yes. Spider AF supports major advertising platforms broadly, including Google Ads (with P-MAX), Yahoo! Ads, Meta Ads (Facebook / Instagram), LINE Ads, X Ads, and various DSPs. Support for new placements and formats continues to expand.
Yes. Spider AF Fraudulent Lead Protection can detect and identify fraudulent conversions such as unreachable numbers, spam, and duplicate submissions. It can also exclude them from media-platform conversion measurement when needed, improving the learning accuracy of ad auto-optimization. One case reduced invalid leads from 95 to 5.
A free diagnostic reveals an account's invalid click rate, unsafe placements, the number of fraudulent conversions, and estimated wasted spend through a loss simulation. The results can be used directly as advertiser proposal material. Setup only requires a tag, and results can be reviewed in as little as a few days.
There are three main benefits. First, removing invalid clicks and fraudulent leads can improve performance metrics such as CPA and ROAS. Second, it enables more persuasive proposals backed by delivery-quality and conversion-quality data. Third, it helps agencies differentiate themselves by extending the proposal value all the way to advertising reliability.
Pricing is monthly and depends on the solutions you use (ad fraud protection, fraudulent lead protection, and SiteScan) plus account size. There is no upfront fee, and you can start with a free diagnostic. Please contact us for detailed pricing.
First, a free diagnostic shows the current state of the account, the room for improvement, and an ROI simulation. Then, after proposal and agreement with the advertiser, full implementation begins with tag placement. Once live, detection status can be checked in the dashboard at any time, and recurring reports are generated automatically. Typical time from implementation to go-live is one to two weeks.
Spider AF is designed so that proposals to advertisers do not end as one-off projects.
Through our partner program, they can be turned into recurring revenue and a repeatable proposal model.
Reseller partners can bundle Spider AF with their own offerings, while referral partners focus on introductions and meeting setup.
No minimum quotas or referral volume requirements. Commission is paid monthly after the referred client clears their invoice.
Spider AF handles all sales, technical onboarding, contracting, and billing — so you can focus on referrals.
By first understanding current performance in measurable terms,
you can more clearly identify both the need for a proposal and its priority.
If you are considering fraud protection that supports client explanations, ongoing proposals, and performance improvement, start with a free diagnostic or proposal consultation.
