Free Ad Diagnosis Tool vs Otterly.AI in 2026: paid-campaign triage vs AI visibility monitoring

Free Ad Diagnosis Tool is a browser-based questionnaire from NEO Digital Marketing for an advertiser who knows a paid campaign is wrong but has not yet isolated the likely failure point. The user chooses Google Ads or Meta Ads and starts with a concrete problem such as poor lead quality, high cost per lead, a performance decline, high CPC, enough leads but insufficient sales, or uncertainty about the problem. Follow-up questions adapt to that choice rather than applying one generic PPC checklist to every campaign.

The Google path can ask about campaign type, search-intent fit, spend, clicks, leads, Quality Score, location targeting, tracking, and the post-click experience. The Meta path can cover creative format, objective, audience approach, spend, impressions, reach, clicks, leads, frequency, and lead capture. With the relevant supplied inputs, it calculates directional CPC, CPL, conversion rate, CTR, CPM, frequency, and, for short video, hook and hold signals from three-second views and ThruPlays. The result identifies a likely weak stage, gives a health score and confidence figure, and lists up to four next checks.

The useful limitation is also the hard limit: the product sees only what the user enters. It does not connect to Google Ads or Meta Ads, verify measurement, monitor a campaign, save a team workspace, send scheduled reports, or publish an API. It is free to use with no published paid tier and offers a printable result plus a local comparison with the last diagnosis on the same platform. Use it to choose what to inspect in the live account and analytics next, not to justify changing spend, targeting, or creative from the score alone.

Otterly.AI is an AI-search monitoring product, not a paid-campaign diagnostic. It tracks brand mentions and answer position across ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Microsoft Copilot, Claude, and Gemini. The tool also records citation links and cited domains, which helps a content team see who is being referenced in answers about its category. This is useful evidence for deciding what content or authority work may improve visibility, but it does not reveal the quality of Google Ads clicks, Meta lead capture, or campaign measurement.

The GEO audit is the product’s action layer. Rather than presenting only a mention count, Otterly identifies gaps in a brand’s AI-search presence and provides optimization recommendations. Domain ranking and citation intelligence can show which competitors or third-party sources recur in AI answers. Answer ranking monitoring adds another useful dimension, because a mention buried low in an answer is different from a prominent recommendation. The output still needs human judgment: citation and mention changes are signals to investigate, not a guaranteed explanation of commercial performance.

Lite is listed at $29 per month for 15 prompts across four base AI engines, with additional coverage for Gemini, Google AI Mode, and Claude sold as add-ons. Standard is $189, Premium $489, and Enterprise starts from €1,000 monthly. GEO audit and citation link analysis are listed across tiers. API access and MCP integration start on Standard, while white-label delivery is not listed for Lite, Standard, or Premium. Choose Lite for a small monitoring program; move to Standard only when programmatic access or an agent workflow is worth the large jump in price.
