How to Choose Google Ads Keywords: A Complete Method

To choose Google Ads keywords, start with commercial intent, check demand and the live SERP, then organize terms into coherent groups. Use the right match type, add negative keywords, and evaluate results before increasing bids.

In short

  • Should you pick the keywords with the most volume? No, not if the people typing them want information or a job rather than a product.
  • Should you look at Google's results page before you bid? Yes, it shows whether the search brings buyers for your offer.
  • Can a low-volume keyword deserve a bid? Yes, if it describes a profitable offer precisely.
  • Can you start with broad match? Yes, with reliable conversion tracking and a maintained negative keyword list; otherwise, start with phrase or exact match.
  • Should you prepare negative keywords before launch? Yes, for the intents you do not serve, such as free, jobs, or used.

Key takeaway: A good Google Ads keyword brings people who are ready to buy what you sell: check the intent before you bid, so you only pay for clicks that can convert.

The method, step by step

  1. Step 1 — Define the offer and objective

    Describe the product or service, target customer, service area, and desired action. List searches that express a purchase-related need, then separate them from questions and branded searches.

  2. Step 2 — Generate and organize ideas

    Use your categories, pages, and customer vocabulary to build a first list. Check variations with Google Keyword Planner or Keywords Everywhere. Classify terms by intent, product, brand, question, and location.

  3. Step 3 — Check demand and the SERP

    Compare volume and CPC ranges with the live results page. Check the ads, organic page types, and the fit between intent and your offer. Remove terms where the underlying need does not match your business.

  4. Step 4 — Choose match types and exclusions

    Assign exact match to precise intents, phrase match to close variants, and broad match to controlled tests. Prepare negative keywords from incompatible searches, then decide whether each exclusion belongs at ad group or campaign level.

  5. Step 5 — Launch, measure, and refine

    Launch groups with consistent ads and landing pages. Track search terms, conversions, cost per conversion, and generated value. Keep relevant terms, adjust bids according to results, and add new exclusions regularly.

1. Start with the business objective

A good keyword matches a real offer, a page that can persuade, and a measurable action. Search volume alone does not define it. Before opening a tool, write down the outcome you want: a sale, a quote request, an appointment, or a sign-up.

Next, describe your ideal customer in the words they would actually use. List the problem they are trying to solve, the product they may compare, and the factors that influence the decision. This becomes your starting material and keeps you away from broad terms that attract unrelated searches.

Purchase maturity matters as much as the topic. A query such as ‘hiking shoes’ may indicate exploration. ‘Buy waterproof hiking shoes size 9’ shows a more specific expectation. Both terms can belong in an account, with different budgets and landing pages.

The keyword you choose also affects ad quality. Our Quality Score guide connects the query, the ad, and the landing page.

2. Find ideas and check demand

Begin with your categories, products, brands, and the problems they solve. Add vocabulary variants, important features, locations, and action-oriented wording. Separate branded terms, generic terms, and questions. This makes it easier to align ads and landing pages later.

Google Keyword Planner gives you keyword ideas, search volumes, and CPC ranges for free. It also provides campaign forecasts, with a Google Ads account. Exact volumes require an account with active spend; otherwise, you may see ranges. Use this data to estimate demand, rather than treating it as the bidding decision.

Keywords Everywhere shows volume, CPC, and competition right inside Google. It adds related keywords and ‘people also ask’ questions, and supports data export. The extension is useful for quickly observing the wording that appears around a search. Its Gold and Platinum plans add a purchase-intent filter through Keyword Keg, but it gives no per-keyword bid verdict for your offer.

Demand is only one input. A low-volume term can be valuable when the offer is specialized. A popular keyword may consume budget while attracting students, researchers, or people looking for a free solution.

Three free tools on this site speed up that first list. The keyword mixer combines 2 to 4 word lists, such as products, features, and cities, into every possible keyword. The keyword intent checker estimates the intent and buying probability of up to 10 keywords at a time, without knowing your offer. The match type generator then writes the list you keep in broad, phrase, and exact match, ready to paste into Google Ads.

3. Read intent through the SERP

Google's results page shows intent better than any volume figure. Search each keyword group in Google and study the page. Paid ads indicate commercial activity, though they do not guarantee profitability. Organic results reveal the expected content type: product page, comparison, guide, local page, or tool. To recognize the main types of intent, see our guide to search intent for Google Ads.

Four questions are enough to judge a keyword from its results page. Do the results match the need your offer addresses? Do the ads promote a similar product? Does your landing page fit the query? Could the click lead to the action you want? When several answers are negative, the keyword often belongs in ‘Skip’.

Should I Bid does this reading for you, keyword by keyword. Its intent analysis reads live organic results and paid ads, then an AI reads the pages that rank there. It combines all of this with the company context and returns a verdict for each keyword: Bid, Test, or Skip. Its score out of 100 combines intent fit, purchase maturity, competitive signal, and commercial signal from the results page.

The score follows simple thresholds: Bid from 70, Test from 50 to 69, and Skip below 50. Its four signals weigh 40%, 30%, 15%, and 15%, with an alignment bonus of up to 15 points. Always compare the result with your margins, conversion rate, and sales capacity. To compare the tools that read the SERP, see our roundup of SERP analysis tools for PPC.

4. Choose the right match type

Exact match gives you the most control over the searches that can trigger an ad. It suits terms with clear intent and segments that deserve close profitability monitoring. Example: [waterproof women’s hiking shoes] can isolate a search that is very close to the offer. Reach is usually narrower and more focused.

Phrase match covers searches that keep the central meaning of the wording. It may suit a group such as ‘waterproof hiking shoes’, where extra words specify size, color, or delivery location. Review the actual search terms and add exclusions when the meaning drifts.

Broad match provides the widest coverage. It can help discover variants and support a strategy based on conversion signals. Example: hiking shoes could reach related searches about equipment or outdoor activities. Use it with a clear offer, reliable conversion tracking, and a maintained negative list.

An account can combine all three types, as long as each one has a clear role. Use exact match for sensitive segments, phrase match for structured groups, and broad match for controlled discovery. Avoid mechanically duplicating every term across every type. Compare search quality, cost per conversion, and generated value.

Google Ads matching rules can change. Check the official documentation on keyword matching options before building a complex structure.

5. Add negative keywords

Negative keywords stop an ad from showing on searches that do not fit your offer. They protect budget and make performance data easier to interpret. Start with incompatible intent such as free, jobs, training, definition, used, or support, when those topics are outside the business.

Each exclusion depends on what you sell. Return to the hiking shoe example. A store selling only new products could exclude used, repair, and rental. A store that does not deliver to a location could exclude searches explicitly tied to that location. Check every exclusion, because an apparently negative term may still describe a profitable product.

After launch, the search terms report shows which real searches triggered your ads. Google describes it in its help page on the search terms report. Review it regularly. Look for unrelated queries, products missing from the catalog, services you do not offer, and purely informational questions. Add exclusions at campaign or ad group level according to their intended scope.

Should I Bid prepares these negatives before launch. Each analysis recommends negatives: the keywords with a Skip verdict, in exact match, and phrase match guardrails around the keywords you keep, checked against your company’s keywords. Inclusion and exclusion lists export to a CSV ready for Google Ads, in exact match. You still need to monitor the actual triggered terms after launch.

6. Full example: a hiking shoe store

As an illustration, take a US online store that specializes in waterproof hiking shoes for adults. Its goal is sales, with healthy margins and delivery across the United States. It has separate landing pages for women’s and men’s shoes. It does not rent equipment or sell used shoes.

The first list groups four families of searches. They are ‘buy waterproof hiking shoes’, ‘waterproof women’s hiking shoes’, ‘waterproof men’s hiking shoes’, and ‘which shoes for hiking in rain’. Google Keyword Planner helps identify demand and variants. The SERP shows that the first two families include ads and product pages close to the offer.

Each family gets the match type that fits its intent. The store uses phrase match for ‘buy waterproof hiking shoes’ to cover commercial variants. It tests [waterproof women’s hiking shoes] in exact match on the women’s page. The rain hiking question goes into a content campaign or a limited test because the SERP appears more informational. The final decision depends on observed conversions.

The starting negatives follow from what the store does not sell. They include rental, used, repair, jobs, and free, and are reviewed once search terms appear. Ads mention waterproofing and lead to the page that matches the searched gender. Each group stays focused enough to make performance analysis useful.

With Should I Bid, the team can go from idea to verdict in one tool. It generates ideas from a product or URL through the Vision module, classifies them as branded, non-branded, generic, or question, removes duplicates against history, and launches the analysis. It can target the US market, choose the device, and manage several clients for agency work. It works with credits, one credit per keyword analyzed, with 5 free analyses to try it and no credit card: see pricing.

After launch, the store judges each keyword on its economic results. It compares triggered searches, conversions, cost per conversion, and sales value. A keyword stays active when those signals are consistent. A term may be reduced or excluded when its traffic remains distant from the offer, even if its volume looks attractive.

FAQ

How many keywords should a Google Ads campaign contain?

There is no universal number. Start with searches that clearly express your offer and group them by intent. A short, coherent campaign often produces data that is easier to interpret than a long list of distant terms. Add keywords after reviewing search terms, conversions, and cost per conversion.

Should you prioritize exact, phrase, or broad match?

Use exact match when you want to isolate a precise intent, phrase match for close variations, and broad match to discover more searches. The choice depends on conversion tracking, budget, and your ability to review triggered terms. Combine match types when each one has a clear role.

How do you find the right negative keywords?

Start with searches that do not fit the business, such as free, jobs, used, or rental when those topics are outside the offer. Then review the search terms report regularly. Add exclusions after checking their meaning, and choose campaign or ad group level according to the intended scope.

Is search volume enough to choose a keyword?

No. Volume indicates potential demand, but it does not prove commercial relevance. Check intent, the displayed results, visible competition, landing page fit, margin, and conversion likelihood. A lower-volume term may be more useful when it closely matches a profitable offer.

Why analyze the SERP for Google Ads?

The SERP shows what Google displays for a query, including organic results and paid ads. It helps identify whether the intent is commercial, informational, local, or comparison-led. This complements volume and CPC data by checking the fit between the search, your offer, and your landing page.

Does Should I Bid replace Google Keyword Planner?

No, the tools serve different purposes. Google Keyword Planner provides ideas, volumes, CPC ranges, and campaign forecasts. Should I Bid gives no search volume and no cost-per-click estimate: it reads the live SERP, considers the company context, and returns a bidding verdict for each keyword. The two work together when you prepare a campaign.
