Google Ads Market Research: Demand, CPC, Competitors & Budget

Define one commercial market before collecting a giant keyword list.

“Google Ads for a dentist in Ireland” is too broad to produce a useful plan. “Dental implants in Dublin” is a much clearer market: one treatment, one location and one meaningful conversion path. The narrower definition gives demand, CPC and competitor data a context.

I usually define the market with four inputs: the service or product, target geography, target customer and primary conversion. If one of those changes materially, the market may deserve separate research.

Measure commercial search demand, not every phrase related to the topic.

Search volume can make a market look attractive while much of the volume comes from education, jobs, DIY or early-stage research. I group keywords by intent and look for the searches that plausibly lead to a provider, quote, booking or purchase.

The detailed process is covered in Google Ads Keyword Research.

CPC is useful when it helps answer a budget question.

A historical CPC or top-of-page bid signal is not a quote for the next click. It describes past market pressure around a keyword. I use it to compare services, locations and keyword groups and to estimate how many clicks a test budget may realistically buy.

For Ireland, the Ireland Search Demand Report adds a broader cross-sector demand view, while the Irish Google Ads CPC Benchmark gives a transparent cross-sector reference, while the Keyword CPC Checker is more useful for one specific term and location.

Competitor research should separate what is observable from what is private.

Before launch, you can inspect public ads and landing pages and identify recurring offers, service angles and calls to action. Once your own campaigns have enough eligible data, Auction Insights can show which advertisers overlap with you in auctions.

What you cannot know from public research is a competitor's exact monthly budget, actual CPC, conversion rate, customer value or profitability. Third-party estimates can be useful context, but they should be labelled as estimates rather than facts.

• Record which advertisers appear repeatedly for the same intent.
• Compare the promise in the ad with the content on the landing page.
• Note whether competitors lead with price, speed, proof, location or a specialist service.
• Avoid copying an offer without understanding whether the business can deliver it profitably.

Landing pages reveal how the market expects a click to convert.

Competitor research is incomplete if it stops at the ad. The destination page shows whether the advertiser is selling a quote, consultation, booking, ecommerce purchase or some other conversion. It also reveals the level of trust and information the market may require before the user acts.

I do not copy competitor pages mechanically. I use them to identify common friction points and then compare those expectations with the business's actual strengths. A smaller business can compete with a clearer offer and better message match even when it cannot match a large advertiser's brand presence.

Build a budget scenario from click capacity and conversion economics.

Instead of asking “What budget should I spend?”, start with the market. If a realistic CPC range suggests a €1,000 budget could buy roughly 100–200 clicks, the next question is what conversion rate and customer value would make that traffic useful.

See Google Ads Budget Planning for the full framework.

Label every research input by confidence.

One of the easiest ways to make market research look more certain than it is involves mixing observed and estimated data. I separate three categories:

• Observable: public ads, landing pages, your own search terms, your own conversion data and eligible Auction Insights.
• Estimated: keyword volume, CPC ranges, bid ranges and third-party modelling.
• Private: competitors' exact budgets, bids, conversion rates, CRM quality and profitability.

This simple distinction improves decision quality because it shows which conclusions are strong and which should remain hypotheses until the campaign creates first-party data.

The output of research should be launch, narrow, change or wait.

A research document that ends with twenty charts but no decision has not finished the job. The market may support a focused launch, but it may also show that the location is too broad, one service should be tested before the rest, the budget cannot buy enough traffic to learn, or the economics are not ready.

Replace estimates with first-party data as soon as the campaign starts.

Pre-launch research is a planning model. Once ads run, Search Terms, actual CPC, conversion quality, location performance and customer feedback become more valuable than the original estimates. The research should therefore create a baseline you can compare with reality rather than a permanent forecast.

That is also why small controlled tests are useful: they turn assumptions into evidence without committing the full budget before the market is understood.
