Your ads are eligible to appear when one of your keywords or search themes matches a user’s search term on Google or on search partner sites. Learn more about keyword matching options and about search themes in Performance Max campaigns (beta).
If multiple keywords, targeting the same domain, are eligible to match the same search term, they don't compete with each other in the auction. For example, you might have the keywords 'skydiving course' and 'skydiving training course' in the same ad group, and both could match the search term 'training course for skydiving'. Only one of those keywords can trigger an ad for the search term. The table below explains which keywords are prioritised to enter the auction.
Note: When your ad enters the auction, it’s then compared with ads from other advertisers, and your cost-per-click is what's minimally required to clear the ad rank thresholds and beat the Ad Rank of the competitor immediately below you, if any.
| Priority | Match characteristics | Explanation | ||
| 1 | Exact match keywords that are identical to the search term | For the search term 'skydiving licence', the identical* exact keyword [skydiving licence] in the search campaign is prioritised over any other broad or phrase keyword or a Performance Max campaign. | ||
| 2 | Phrase and broad-match keywords or search themes that are identical to the search term | For the search term 'skydiving licence', the identical* Performance Max search theme 'skydiving licence' is prioritised over the phrase keyword 'skydiving'. In this case, the phrase keyword isn't identical to the query. | ||
| 3 | Relevance: AI (artificial intelligence) based keyword prioritisation |
The search term 'skydiving certifications near me' could match to keywords in several ad groups, some of which may be more relevant, such as 'skydiving licence', and others may be less relevant, such as 'skydiving courses for beginners'. In this case, only the most relevant keywords from the most relevant ad groups are considered. Learn more about how AI keyword prioritisation works. |
||
| 4 | Ad Rank | If you have several search keywords or Performance Max search themes that share equal priority based on the criteria above, the ad or asset group that generates the ad with the highest Ad Rank will be prioritised. |
*'Identical' includes spell-corrected search terms, such as skydoving licence, but doesn’t include plurals or synonyms like licence for skydiving.
How AI is used to prioritise the most relevant keywords
If your keywords aren't identical to the search term, AI-based keyword prioritisation ensures that only keywords from the most relevant ad groups are matched to your search term. Relevance is determined by the meaning of the search term, all the keywords in an ad group and landing pages within the ad group. Note that AI-based keyword prioritisation works on keyword based search campaigns.
Example
For a user searching 'skydiving certifications near me', consider the following ad groups containing broad-match keywords:
Ad group 'Skydiving licence'- Keywords: Skydiving licence, how much is a skydiving licence
- Landing page: Specific page outlining the licensing process
- Keywords: Advanced skydiving courses near me, advanced skydiving lessons
- Landing page: Specific page for advanced courses
Because both advanced courses and licences have related intent, a search for 'skydiving certifications near me' can match both ad groups under broad-match. Learn more About keyword matching options.
However, as per AI based prioritisation, only the 'Skydiving licence' ad group enters the auction because 'licence' and 'certifications' are significantly more related than 'courses' and 'certifications'.
Note that for a search like 'advanced skydiving courses to get licensed', keywords from both ad groups have a similar relevance, so the keyword with the higher Ad Rank enters the auction.
Exception to preferences
A campaign is limited by budget
One of your search keywords or Performance Max search themes isn’t eligible to trigger an ad
An ad format doesn’t compete with your search keywords or Performance Max search themes
Keywords, Dynamic Search Ads and Performance Max
Dynamic Search Ads and Performance Max ads without search themes are equivalent to keywords that don’t exactly match the search term for selection preference. If a keyword isn't identical to a search term, Dynamic Search Ads and Performance Max ads are selected based on the highest Ad Rank compared to other search keywords in the account. The same exceptions to preferences apply.
Search themes in Performance Max campaigns will have the same prioritisation as phrase and broad-match keywords in search campaigns.
