Do Google Reviews Affect Your Google Ads and Local Services Ads?

Two different products, two different answers

"Google Ads" and "Local Services Ads" get used interchangeably, but they're separate systems with separate rules for how reviews come into play. Standard Google Ads (the search and display campaigns most businesses run themselves or through an agency) is one thing. Local Services Ads — the pay-per-lead listings with the green checkmark that appear above regular search results for trades and local services — is another, and reviews sit much closer to its core.

Conflating the two leads to two common mistakes: assuming a pile of reviews will lift a standard search campaign the way it lifts organic rankings, or assuming Local Services Ads works like a normal auction where reviews are just one input among many. Neither assumption holds.

Standard Google Ads: reviews aren't a direct ranking input

Ad Rank in a standard Google Ads campaign is built from your bid, ad and landing page quality, expected click-through rate, and the competitiveness of the auction. Your Google Business Profile review count and star rating are not one of those inputs — Google doesn't read your review history and adjust your ad position because of it.

Where reviews can show up is visually, through review-based ad extensions and shopping-style seller ratings that pull a star rating from aggregated review sources into the ad itself. A visible star rating can lift click-through rate, and click-through rate does feed into Quality Score over time — so the effect is real but indirect, running through customer behaviour rather than a direct scoring rule.

Google sets its own minimum thresholds for how many reviews you need, and how recent they need to be, before it will display a rating alongside an ad. Those thresholds aren't fixed or published as a single number and change over time, so treat any specific figure you see elsewhere as indicative rather than something to plan around precisely.

Local Services Ads: reviews are part of the product, not a side effect

Local Services Ads is built differently. The ad unit itself displays your star rating and review count front and centre, and Google has said publicly that reviews are one of the signals — alongside proximity to the searcher, responsiveness to enquiries, business hours, and its own vetting (licence and insurance checks, background checks where relevant) — that influence where you appear.

This is also the product behind the Google Guaranteed and Google Screened badges, which exist specifically to signal vetted trust to a searcher choosing between several similar tradespeople or local services on the same page. A thin or dated review history sits at odds with the whole point of the badge, even before Google's ranking mechanics come into it.

What this actually means for how you spend your time

• If you run Local Services Ads: treat your Google review flow as part of the campaign, not a separate project — responsiveness and review activity are levers you can directly influence, unlike the auction dynamics of standard search ads.
• If you run standard Google Ads: don't expect review volume to move your ranking directly. Put ad-side effort into quality score fundamentals — relevance, landing page experience, bid strategy — and treat reviews as a trust signal that helps conversion once someone lands on your site, not a ranking lever.
• Either way, a stronger reputation tends to lower your effective cost of acquisition even without a direct ranking effect, because a visible rating and a track record of thoughtful replies both improve how a stranger reads your ad before they've spoken to you.
• Pausing or stopping a Google Ads or Local Services Ads campaign has no effect on your existing reviews — they live on your Business Profile independently of whichever ad products you're running.
