Should you use Performance Max or a Search campaign?

Consider Performance Max when you can define a valuable customer action and are comfortable advertising across channels. Google positions it as a complement to keyword-based Search campaigns, with access to Search, YouTube, Display, Discover, Gmail and Maps. Campaign coverage and recommended uses.

A conversion means a customer action you choose to measure, such as a purchase or enquiry. For your first test, write a precise definition. “A homeowner requesting a quote within our service area” is more useful than “engagement”.

Make the choice around your situation

For performance max vs search campaigns, avoid making a replacement decision purely because one option uses more automation. Keep a record of what your existing campaigns achieve before changing the mix. For a broader channel decision, use the SEO versus Google Ads guide.

What should you prepare before campaign setup?

Prepare a short launch brief with an offer, a measurable action, a working destination page and a spending boundary. Google lists conversion goals, creative materials, audience signals and budget settings among the campaign inputs. Audience signals are information about the customers you want to reach that helps guide learning. Performance Max setup inputs.

Your launch brief

• Offer: describe exactly what customers can buy or request.
• Destination: choose a page that explains that offer clearly.
• Measurement: name the action that counts as success.
• Materials: gather current text, images, logos and suitable video.
• Owner: appoint someone to check enquiries and answer customers.
• Boundary: record the total test spending you can accept.

Before launch, complete the customer journey yourself on a phone. Place a test order or submit an enquiry, then ask whoever manages measurement to show where it appears. Check whether the same action has been counted twice.

If the form or page needs work, follow the conversion rate optimization guide. Treat that as preparation for buying traffic. Do not leave basic questions about your offer for the advertising system to resolve.

Hypothetical example: a catering business wants corporate lunch bookings. I would give this campaign a page about office lunches, with delivery coverage and a clear request form. I would keep wedding packages out of the initial creative brief.

How does Smart Bidding work, and what budget makes sense?

Smart Bidding automatically calculates bids during advertising auctions using the likelihood of a conversion. Performance Max also allows optional CPA or ROAS targets. Google's explanation of bidding.

For planning purposes, CPA means advertising cost per measured action. ROAS compares recorded conversion value with advertising spend. Decide whether your business should focus on the cost of a suitable enquiry or the value of completed purchases.

Start with your own economics

Write down what remains from a sale after the product and other variable costs. Then decide how much of that amount you can put toward acquiring the customer. For enquiries, review your own sales records before assigning a value to each request.

I would not copy another company's performance max budget. Instead, agree on a test allowance, a review point and conditions for stopping. A broken checkout or incorrect offer should prompt immediate attention, even if the planned review is later.

Google provides budget recommendations and performance forecasts during setup. Use those as inputs to your decision, alongside the amount your business can afford. Budget recommendations and forecasts.

Record who may change the budget and what evidence they should bring. If several people manage advertising, use the ad budget management guide to document that responsibility.

How should you organize Performance Max asset groups?

Organize each group around one coherent offer or customer need. An asset group is a collection of text, images, logos and videos around a theme or audience; Google combines those materials into ads. Google's asset group definition.

Review combinations, not just individual files

Hypothetical example: a small homeware shop sells desk lamps and outdoor lighting. I would prepare separate material sets for these offers. A desk lamp headline should make sense beside every image in its group and on the destination page.

• Use photographs of products the customer can actually order.
• Write benefits that answer a buying question.
• Check that delivery promises match current operations.
• Remove images with outdated discounts.
• Have another person review the previews before launch.

For each headline, ask what a customer would reasonably expect after clicking. If the answer is absent from the page, change the headline or improve the page. Keep the promise and the buying experience aligned.

A short creative brief helps here: product, customer, main benefit, supporting detail and next action. Use the ad copy prompt examples to draft alternatives, then check every claim yourself.

Which automated settings need your attention?

Review automatic text generation and destination selection before launch. With Final URL expansion enabled, Google may send a visitor to a different relevant page; text customization can generate additional headlines and descriptions from your website and existing ads. You remain responsible for their accuracy. Creative and destination controls.

A practical review sequence

1. Read the pages that could represent your offer.
2. Correct expired promotions and discontinued services.
3. Check the automatic settings against your intended customer journey.
4. Review available brand and search controls.
5. Record the settings you chose and why.

Google lists negative keywords and brand exclusions among its campaign controls. These help exclude unwanted searches or brands. Review them against real business needs instead of adding exclusions without a clear reason. Search and campaign controls.

My suggested check is straightforward: could a customer see an offer you would refuse to honour? If so, fix the page or material before continuing. Keep an owner responsible for checking generated content as the campaign runs.

How do you judge Performance Max results?

Start with overall business results, then investigate the details. Google's reporting article describes channel, search-term and asset reporting, while warning against judging a channel only by its average return over a short period. How Google describes campaign reporting.

Build a review that ends in a decision

Bring advertising spend, recorded conversions and your actual sales or enquiry records to the same review. Ask which enquiries were suitable, which purchases were completed and what still needs checking. Choose your measures with the small business KPI guide.

• Do the reported actions match your business records?
• Are enquiries about the service you advertised?
• Are staff responding while the request is still relevant?
• Does the destination page answer recurring questions?
• What single change should you test next?

Hypothetical example: an installer receives requests for products they do not supply. I would inspect the search terms, wording and destination page before increasing spending. The next change should address the mismatch you found.

Google describes using search-term reporting to identify unsuitable searches and apply negative keywords where appropriate. Its asset reporting also helps identify materials worth investigating. Search-term and asset reporting examples.

If you are comparing how different customer touchpoints receive credit, read the marketing attribution guide. In your own review, distinguish the campaign's reported contribution from proof that every sale would otherwise have been lost.

Your first week's work

Use this week to settle the goal, test measurement, prepare one coherent offer and review the controls. Schedule the next review before launch. Treat the first week as a preparation and checking period, rather than a deadline for proving long-term profitability.
