How to tell if a competitor is outspending you on ads

The question comes up in every board meeting: are they outspending us. The honest answer is that nobody outside their ad account knows, including every tool that will happily show you a number.

But there are free signals that tell you more than the number would.

Why every estimate is modelled

For paid search, tools estimate spend by taking the keywords a domain appears for, multiplying estimated monthly volume by an estimated click through rate for the observed position, then multiplying by an estimated cost per click.

Four estimates multiplied together. Each is individually reasonable and the compounded error is large.

For display and social, it is panel data and observed impressions multiplied by an assumed CPM. Same structure, same compounding.

The result: two credible tools looking at the same advertiser commonly differ by three times. Neither is lying. They are modelling.

What estimates are good for. Comparing two advertisers inside the same tool, and watching one advertiser's trend over time in that tool.

What they are not good for. Any sentence containing the word "actually", and any client report where the number appears as fact.

The free signals that beat the estimate

All of these come from the official ad libraries, which are free and published by the platforms themselves.

1. Duration

Sort their ads by first shown date. An ad that has been running eight months is a working ad, because nobody funds a losing ad for eight months.

A wall of ads all started in the last three weeks means they are in a testing phase, which means the spend is exploratory rather than committed.

This is the single most reliable free signal of investment. It requires no modelling at all.

2. Creative volume

Count distinct concepts, and count variants within each concept.

One concept in fifteen variants means they found something and are optimising it. That is a team, and it is budget.

Six concepts in one variant each means they are still searching.

Producing creative costs money. Volume of creative is a direct, observable proxy for investment that nobody has to estimate.

3. Channel spread

Running on Google, Meta and TikTok simultaneously, with distinct creative for each, is a real budget with a real team. Nobody manages three channels properly on a small spend.

One channel with four ads is a side project.

4. Landing page investment

Open the pages behind their ads. A dedicated landing page, built for that campaign, with custom design and a tested form, costs money to make.

Ads pointing at the homepage mean nobody is funding the conversion side, which usually means the campaign is not being taken seriously internally.

5. Geographic and language spread

The Google Ads Transparency Center shows which regions each ad runs in. Ads running in eight countries with localised copy is a substantially bigger operation than the same ads in one.

Putting it together

Score a competitor on those five, weekly, and you will have a better read on their commitment than any dollar estimate gives you. And it is free, observable and reproducible, which the estimate is not.

A worked read might be: fourteen live ads, four running over six months, three concepts, two channels, dedicated landing pages, two countries. That is a funded, working programme, probably with an agency or a dedicated person. You do not need a number to act on that.

Compare with: twenty three ads, none older than five weeks, eleven concepts, one channel, all pointing at the homepage. That is somebody testing with a modest budget and no conversion support. Completely different situation, same superficial ad count.

What to do with the answer

Here is the uncomfortable part. Even if you knew their exact spend, it would not tell you what to do.

Spend is an input. The output is customers per dollar. A competitor spending twice your budget on a worse landing page with a weaker offer is losing money faster than you are.

Three better questions than "are they outspending us":

Are they running ads we cannot answer? An offer, a proof point or a guarantee you have no response to. This is a real problem and it is visible in the creative for free.

Are they buying our brand name? Search your own brand and see. If they are, you have a specific, fixable issue.

Is their landing page better than ours? Open it. Compare honestly. This is the cheapest competitive improvement available and it needs no budget at all.

Keeping an eye on it

The five signals above take about fifteen minutes per competitor per week in the free libraries, and the value is in the trend rather than any single reading.

That weekly habit is the thing that fails. Our own Figo checks the Google, Meta and TikTok libraries weekly for every competitor you track and reports what started, what stopped and how long each creative has been running, at $49 a month for three competitors. Adbeat at $249 a month is the right tool if programmatic display is part of the picture, and SpyFu at $119 after the intro month if paid search history matters.

None of them, ours included, can tell you what anyone actually spent. Be suspicious of any vendor who implies otherwise.
