Let me cut through the noise: most people searching for keywords in Google Ads are doing it backwards. They open Keyword Planner, type a broad term, grab the highest-volume suggestions, and dump them into a campaign. That’s not keyword research — that’s gambling with your budget.
If you actually want to know how to search for keywords in Google Ads without setting money on fire, you need to treat Keyword Planner as a starting point, not a final answer. The real work happens when you cross-reference its data with your own search behavior, your competitors’ gaps, and the weird, specific phrases your buyers actually type.
What Keyword Planner Actually Gives You (And What It Hides)
Google’s Keyword Planner lives inside your Google Ads account under Tools > Planning > Keyword Planner. You get two main modes: «Discover new keywords» and «Get search volume and forecasts.» The first one spits out ideas based on a seed term or a URL. The second one validates a list you already have.
Here’s the catch nobody tells you: the volume ranges are deliberately vague. «1K–10K» could mean 1,100 or 9,800. That’s a massive difference when you’re deciding whether a keyword deserves its own ad group. For serious keyword research in Google Ads, you need a second source — Google Search Console, Semrush, or Ahrefs — to triangulate the real numbers.
Another thing: Keyword Planner clusters close variants. «Buy running shoes» and «running shoes buy online» might show as one entry. If you’re doing exact match bidding, that clustering can hide the specific phrase that converts. Always export the CSV and inspect the raw suggestions.
The Long-Tail Goldmine Nobody Bothers to Dig
Everyone chases the fat keywords. «Coffee shop,» «SEO services,» «car insurance.» Good luck outbidding State Farm on that last one. The money in Google Ads keyword search is in the long tail — phrases with 50 to 500 monthly searches that nobody wants because they look small.
Think about it like this: if you run a specialty coffee roaster in Portland, «best single origin coffee near me» is worth ten times more than «coffee.» The intent is razor-sharp. The competition is thin. The click costs a fraction.
To find these, use Keyword Planner’s filters: set competition to Low or Medium, set the volume range to something like 100–1,000, and sort by «top of page bid (low range).» You’ll surface terms that bigger advertisers ignore because they’re chasing vanity metrics.
Long-tail keywords aren’t a consolation prize. They’re the actual game. The broad terms are just the bait you use to find them.
Spy on Your Competitors Without Feeling Guilty
Semrush and Ahrefs both let you plug in a competitor’s domain and see the exact keywords they bid on in Google Ads. This is legal, public data — Google publishes ads for everyone to see. There’s no ethical gray area here.
What you’re looking for isn’t their whole list. You want the gaps. Keywords they bid on with weak ad copy. Keywords where their landing page is generic. Keywords where they’ve been running the same ad for six months — that means it’s working, and you need a sharper angle, not a copy.
Also check the «Paid vs. Organic» split in Semrush. If a competitor ranks organically on a keyword but doesn’t bid on it, that’s a signal they’ve decided it’s not worth the CPC. Sometimes they’re right. Sometimes they’re lazy. You won’t know until you test it with a small budget.
Match Types: Where Most Accounts Bleed Cash
When you add keywords to a campaign, Google defaults to broad match. Don’t accept that. In 2026, broad match with Smart Bidding can work, but only if you’re feeding the algorithm clean conversion data. For most small and mid-size accounts, it’s a money pit.
Use phrase match as your default. It respects word order and catches close variants without going rogue. Reserve exact match for your proven winners. And use broad match only inside a separate campaign with a tight negative keyword list and a strict budget cap.
Speaking of negatives — build that list before you launch, not after. Every keyword search report you pull will show junk queries. «Free,» «cheap,» «diy,» «jobs,» «salary,» «reddit.» Add them as negatives at the account level so they never waste a click again.
Mine the Search Terms Report Weekly (No Exceptions)
The Search Terms Report is where the real Google Ads keyword research happens. It shows you the actual queries that triggered your ads. Not your keywords — the queries. Those two things are often wildly different.
Here’s the routine I’d defend with my life: every Monday, pull the last seven days of search terms, sort by cost, and go down the list. Anything irrelevant becomes a negative. Anything relevant with decent conversion potential becomes a new exact-match keyword in its own ad group. Anything with impressions but no clicks gets a new ad variant written specifically for it.
This loop is boring. It’s also the difference between a 2% conversion rate and a 6% one. The people who skip it are the same people who complain that Google Ads «doesn’t work anymore.»
Use Google Suggest and People Also Ask as Free Keyword Tools
Before you even open Keyword Planner, go to Google and start typing your seed term. The autocomplete suggestions are pulled from real search behavior. They’re free, they’re current, and they reveal phrasing you’d never guess.
Then scroll to «People also ask» and «Related searches.» These are goldmines for question-based keywords, which work beautifully in Google Ads because they match high-intent, research-stage queries. «How much does X cost,» «Is X worth it,» «X vs Y» — these convert because the searcher is close to a decision.
Copy those phrases into a spreadsheet, run them through Keyword Planner for volume, and you’ve got a campaign skeleton in under an hour. No paid tool required for the first pass.
Stop Looking for the Perfect Keyword
There’s no such thing. The keyword that converts at 8% today might drop to 1% in three months because a competitor entered the auction or Google changed the SERP layout. Keyword research in Google Ads isn’t a one-time project — it’s a maintenance habit.
If you take one thing from this: build a system, not a list. A system that pulls search terms weekly, kills waste monthly, and tests new long-tail phrases constantly. That beats any «ultimate keyword list» you’ll find on page one of Google.
Now go open that Search Terms Report. It’s been waiting for you.
