"Really recommend Clean Digital, they've been a fantastic agency to work with and we've always been really impressed with the team and the results they produce."
The calculators, tools and guides our paid media team uses on client accounts, free, with no login or email gate. Forecast PPC budgets, check ad test significance, look up creative specs and plan Google Ads, paid social and programmatic campaigns.
…or jump straight to a section:
Four calculators for the money questions that come up on every account: what a budget should return, how to split it across channels, how big a test needs to be, and how much the weather moves demand in your category.
Calculator · Budget modelling · Updated Feb 2026
Enter a monthly budget and get an estimate of the impressions, clicks and leads or sales it should produce, split across channels and benchmarked by industry and country.
Calculator · Channel planning · Updated Feb 2026
Set a budget, a funnel split and a creative mix, and get a cross-channel plan in one view: CPMs, impressions and clicks for Google Ads, paid social and programmatic.
Calculator · Test planning · Updated Mar 2026
Work out how big an A/B test needs to be and how long it will take, from your baseline rate, the lift you want to detect and the confidence level. It stops you calling a test early or letting it run for months.
Calculator · Forecast response · Updated Mar 2026
If demand in your category rises and falls with the weather, your bids can too. See suggested bid and budget changes against the coming forecast for selected verticals.
If the forecast says the account can’t hit the target the way it is set up now, a free Google Ads account audit shows where the budget is going.
Launches fall over on small things: a headline that truncates, an asset a few pixels off spec, a file the placement will not accept. These two tools help you catch those early.
Tool · Search ad QA · Updated Aug 2024
See your search ads laid out the way they appear on Google: headlines, descriptions and sitelinks in a real results layout. Weak or truncated copy is obvious at a glance.
Tool · Creative specs · Updated Mar 2026
Every dimension, ratio, file rule and QA note for Google, Meta, LinkedIn, TikTok and more, filtered by platform, placement and media type. No more digging through each platform’s help docs.
If the creative is on-spec but still not converting, see how our paid social team builds and tests ad creative that keeps working past the first week.
Display budgets leak into junk placements and the wrong audiences, and the platform interface rarely makes it obvious. These two tools show where your budget is going and who your ads reach.
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. Includes a sourced starter kit of the Display exclusions to set first.
Tool · Targeting research · Updated Mar 2026
Describe the business and get back structured audience themes, with a read on which platforms suit each one, a solid first pass for a new market, brief or product line.
Running this at scale across programmatic is a bigger job. See how we run programmatic campaigns built to stay out of junk inventory.
Each of these tools came out of real client work. Find the situation that sounds like yours and go straight to the one that helps.
Finance wants next quarter’s paid media budget, with the numbers behind it.
Forecast the budgetAn ad test has been “almost significant” for three weeks.

Check the spec firstDisplay spend is up and no one can say where the ads actually ran.
Cut wasted placementsA new market launch needs an audience plan by Monday.
Draft the audiencesA tool can show you the problem: leaking spend, an undersized test, placements full of junk. Fixing it often takes someone working in the account. A free ad account audit gets our senior team on it, and the case studies show what that has changed for other clients.
Longer reads on measurement, Shopping, AI search and choosing an agency: the questions clients actually ask us.
New measurement, Google Ads and ecommerce guides land on the Clean Digital blog first, and we work through the live versions in our PPC webinars.
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.
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.
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.
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.
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.
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.
