These two tools help you catch those early.

These two tools show where your budget is going and who your ads reach. [![GDN placement exclusions tool triaging a Google Display Network placement report into keep and exclude](https://cleandigital.co.uk/images/resources/previews/gdn-placement-directory-poster.png)](https://cleandigital.co.uk/tools/gdn-placement-directory) ### [GDN Placement Exclusions](https://cleandigital.co.uk/tools/gdn-placement-directory) Tool · Placement exclusions · Updated Jun 2026 Paste a Google Display Network placement report to flag the mobile app, anonymous and made-for-advertising inventory draining your budget, then export a Google Ads exclusion list.

AI & paid media · Jul 2024 Read the guide](https://cleandigital.co.uk/blog/what-chatgpt-agent-means-for-advertisers) New measurement, Google Ads and ecommerce guides land on the [Clean Digital blog](https://cleandigital.co.uk/blog) first, and we work through the live versions in our [PPC webinars](https://cleandigital.co.uk/webinars). ## Questions about these PPC tools ### What free PPC tools are in this library? Four calculators for budget forecasting, media planning, ad test significance and weather-led bidding; four working tools covering Google Ads previews, creative specs, GDN placements and audience research; and six guides on measurement, shopping, AI surfaces and agency selection. Everything is built and maintained by the Clean Digital paid media team. ### Are the PPC calculators really free? Yes. Every calculator, tool and guide here is free to use with no login and no email gate. They exist because we wanted them for our own client work; publishing them costs us nothing extra. ### How accurate are the budget and forecast calculators? They are directional by design, built on industry and country benchmarks rather than your own account history. That makes them good for setting a rough budget, sense-checking a target or putting a first number on the table, then you refine it with a forecast built on your own data. ### Should I start with a calculator or a guide? Use a calculator or tool when you already know the job: planning a test, modelling a budget, checking a spec. Reach for a guide when the question is still forming: how to measure offline conversions, whether CSS is worth it, or how to compare Google Ads agencies. ### Can these tools replace PPC agency management? They take some of the guesswork out of the decisions around an account (budgets, tests, specs, targeting) but they don’t restructure campaigns, fix tracking or handle the week-to-week work. When one of them points to a problem you can’t fix from a spreadsheet, that’s often the point to book a free ad account audit. ## Found something that needs fixing? Get in touch and our paid media team will audit your ad account for free, then send you a short, ordered list of what’s wasting money, what isn’t tracked properly, and what’s worth testing.
