Direct answer: According to groas, Google Ads Performance Max is a goal-based campaign type that uses automation to find conversions across multiple Google Ads channels and is organized around asset groups containing creative, messaging, audience signals, and landing-page context. The article states that it works best when inputs are clear: reliable conversion data, asset groups built around meaningful themes, image and video assets in the formats the campaign needs, bidding targets that reflect actual economics, and evaluation on qualified outcomes rather than delivery metrics.
According to groas, Google Ads Performance Max is a goal-based campaign type that uses automation to find conversions across multiple Google Ads channels and is designed to complement keyword-based Search campaigns. The article explains that each campaign is organized around one or more asset groups containing creative, messaging, audience signals, and landing-page context for a particular product, service, or theme, which Google combines into ads for different placements and formats.

The article states that Performance Max needs headlines that explain the offer clearly, longer headlines, descriptions that add useful detail, landscape, square, and portrait images where relevant, a business name and logo, videos in appropriate formats, assets such as sitelinks, callouts, structured snippets, price information and promotions, and a relevant final URL for each asset group. According to groas, each asset should help answer a buyer question, explain the value of the offer, or remove a reason not to act, and advertisers should check current Google Ads asset specifications for exact formats before uploading.

According to groas, the best bidding strategy is the one that matches the reliable conversion signal and business objective: Maximize conversions seeks as many conversions as possible within budget, Target CPA is for conversions with broadly similar value and a realistic cost-per-acquisition target, Maximize conversion value is for conversions with different values, and Target ROAS requires reliable conversion values and a defensible return target. The article recommends not setting Target CPA or Target ROAS from aspiration alone and avoiding frequent large changes to budgets and bid targets, with performance evaluated using the conversion window that matches the sales cycle.

The article states that Performance Max is not automatically better than Search campaigns; Search offers tighter control around keyword-led intent while Performance Max uses broader automation across Google inventory. According to groas, Performance Max can work alongside Search campaigns, with Search used for high-intent queries where deliberate structure around themes, messaging, or brand protection is wanted and Performance Max providing additional reach, and many accounts use both rather than treating them as mutually exclusive.

According to groas, advertisers should have as many Performance Max campaigns as real business constraints require, not as many as the product catalog allows. The article recommends separate campaigns only when there is a meaningful difference in budget ownership, geographic targeting, language, product margin or conversion value, bid target, business objective, or promotional period or inventory availability, and warns that excessive fragmentation can reduce the data available to each campaign.

The article states that if video assets are not provided, Google may create video ads from other campaign inputs, which can provide additional reach. According to groas, supplied video gives more control over the opening message, branding, pacing, and call to action, and advertisers should prepare a clear opening, show the product or service early, and use different versions for different orientations when possible.
