Google Search Ads: How to Set Up and Manage a Search Campaign

Google Search ads show your text ad among the results at the moment someone searches Google for your product or service. You decide which searches trigger the ad with keywords, and how much you pay with your budget and bid strategy. Their strength is that they capture search intent that already exists rather than trying to create demand.

How are Search ads different from other Google ads?

On the Display Network or YouTube, your ad appears while someone is reading or watching something else. On Search, the person has typed the need themselves: someone searching "boiler service near me" or "accounting software pricing" is looking for a solution right now. That is why Search is usually the first campaign type launched for service businesses, B2B lead generation and products with clear search volume. We explained how display ads work for awareness and remarketing in our Google Display ads guide.

How should you structure a Search campaign?

The account has three layers:

1. Campaign: Budget, target location, language and bid strategy are set here. Work that needs a different budget or a different target region belongs in a separate campaign.
2. Ad group: Closely related keywords and the ads written for them are grouped here. "Boiler maintenance" and "boiler installation" are different intents, so they should sit in separate ad groups and lead to their own landing pages.
3. Keywords and ads: These should stay faithful to the ad group's theme.

Budget is entered per day. If you think in monthly budgets, Google suggests dividing the monthly amount by 30.4 to get the daily budget. At the start, a small number of clearly themed campaigns learns faster than a budget split across dozens of small campaigns.

What do keyword match types do?

The match type decides which searches your keyword can match. Google Ads offers three:

• Broad match: No special symbol; it is the default. It can show ads on searches that do not contain the keyword but are considered related, so it gives the widest reach.
• Phrase match: Written in quotation marks, for example "tennis shoes". Ads can show on searches that include the meaning of the keyword.
• Exact match: Written in square brackets, for example [red shoes]. Ads show only on searches with the same meaning or intent, which gives the most control.

Google stresses that using broad match together with Smart Bidding is very important. In practice, if conversion tracking is not set up yet or the account has little conversion data, broad match can spread the budget over irrelevant searches. In new accounts, a more controlled path is to start with phrase and exact match and test broad match once conversion data builds up. To find which terms people actually search, see our keyword research guide.

How should you use negative keywords?

A negative keyword excludes searches you do not want your ad to appear on. Terms like "free", "jobs" or "how to" often bring wasted clicks in a sales-focused campaign. Negatives can be added at ad group, campaign or account level; an account-level list is applied automatically to all eligible Search and Shopping inventory.

An easily missed detail: according to Google, negative keywords do not match close variants. Excluding "free" does not exclude a synonym such as "complimentary"; you need to add synonyms and plural forms separately. The best source for growing your negative list is the search terms report, which lists the searches that actually triggered your ads. Review it often in the first weeks, then at regular intervals.

How do you write a responsive search ad?

The standard ad format on Search is the responsive search ad. You enter several headlines and descriptions, and Google shows them in different combinations depending on the search. According to Google Ads help, the limits are:

• Up to 15 headlines, each up to 30 characters; at least 3 are required
• Up to 4 descriptions, each up to 90 characters; at least 2 are required
• Two path fields in the display URL, each up to 15 characters

Because assets can appear in any order, each headline must make sense on its own and next to the others. A good headline set includes, separately: the search phrase itself, a concrete benefit ("Same-Day Service"), a trust element, an offer condition instead of a price ("Free Site Visit", if you actually offer it) and a call to action. You can pin a headline so it always appears first, but Google notes that pinning can reduce the number of combinations and lower ad strength. Keep pinning for cases where it is truly needed, such as a legal requirement or a brand rule.

However good the ad is, if the person who clicks lands on an unrelated homepage, the conversion will not come. We covered the landing page side in detail in our guide to high-converting landing pages.

Which bid strategy should you choose?

Google has four Smart Bidding strategies: Target CPA, Target ROAS, Maximize conversions and Maximize conversion value. They share one requirement, conversion tracking; Google states plainly that you need conversion tracking enabled to use Smart Bidding.

So the first job is measurement, not bidding. Whether it is a form submission, a phone call, a WhatsApp click or a purchase, define the action that is valuable to you as a conversion and test it. Making light actions such as page views or time on site your primary conversion optimizes the algorithm toward the wrong goal. In e-commerce, if order value is also passed through, Target ROAS or Maximize conversion value is a common starting point; for service businesses, a common path is to start with Maximize conversions and move to Target CPA as data builds up.

What does Quality Score tell you?

Quality Score is a diagnostic indicator from 1 to 10, given at keyword level, with three components: expected click-through rate, ad relevance and landing page experience. Google states that Quality Score is not an input in the ad auction; it is a tool to help you find where your ads and landing pages can improve. Instead of chasing the number, look at which component shows "Below average" and fix that area: if ad relevance is low, split the ad group; if landing page experience is low, check whether the page actually answers the search.

What is AI Max, and should you turn it on?

AI Max is Google's package of AI-powered features for Search campaigns. It has three main parts: search term matching, which reaches searches beyond your existing keywords; text customization, which adapts headlines and descriptions to the search; and final URL expansion, which sends the person to a more relevant page on your site. Controls such as brand and URL exclusions are also available.

Our recommendation is to turn on AI Max once your conversion tracking is reliable. After switching it on, watch the search terms report and the pages the ads send people to closely, and exclude addresses that will not bring sales, such as careers, blog or support pages.

Pre-launch checklist
