A landing page is never judged on its own merits. It is judged against the ad that led to it, and against what the visitor was looking for when they clicked. That is what Google Ads measures with the landing page experience component of Quality Score: the official help describes it as an indicator of how relevant and useful your page is to people who click your ad, compared with the other advertisers on the same search over the previous 90 days.
The consequence is uncomfortable. Your page can be perfectly decent and still be rated "below average", simply because competitors on the same query do it better. In the accounts I audit, this is almost always where the gap in cost per conversion sits — well before any work on bids.
What follows is the order I work in, because each step gives the next one meaning.
What Google actually scores
Quality Score rests on three components: expected click-through rate, ad relevance and landing page experience. Each is given one of three states — above average, average, below average. "Average" or "below average" flags room for improvement, not a punishment.
Alongside that rating sits an editorial rule many advertisers discover the hard way, when an ad is disapproved. Google's destination requirements rule out destinations that do not work (404, 403 and 500 errors), pages blocked from crawling by robots.txt, redirects to a domain other than the one displayed, disruptive pop-ups, unsolicited downloads, and pages with no original content that exist only to carry advertising.
So the first checks come before any optimisation: the page returns HTTP 200, it is not blocked in robots.txt, and the domain shown in the ad is the domain the visitor lands on. Tracking parameters and templates must resolve to the same content as the final URL. A short technical check of status codes and redirect chains prevents a run of disapprovals.
Continuity between the ad and the page
Google sums up its own recommendation in one line: give people what they are looking for, by matching the page to the intent behind the query. In practice, a handful of checks.
- The heading at the top of the page uses the words of the ad and the ad group. If the ad promises emergency locksmith cover within the hour, the page cannot be titled "Our services".
- The commercial promise is identical: same offer, same price, same conditions. A gap here is the most common cause of an immediate bounce.
- One page per intent. A single generic page fed by ten different ad groups dilutes the relevance of every one of them.
- The expected action is visible on mobile without scrolling: call, form, booking, quote request.
On the accounts I take over, the biggest saving rarely comes from a new design. It comes from splitting a catch-all page into three focused ones, which often improves perceived relevance without touching the budget.
Speed and Core Web Vitals, INP included
Google's guidance is blunt: load speed can be the difference between a bounce and a sale. The reference metrics are the Core Web Vitals, measured on real visits at the 75th percentile, separately for mobile and desktop.
| Metric | What it measures | "Good" threshold |
|---|---|---|
| LCP | How quickly the largest element is displayed | 2.5 s or less |
| INP | Responsiveness to interactions (taps, typing) | 200 ms or less |
| CLS | Visual stability of the layout | 0.1 or less |
INP (Interaction to Next Paint) is the one most often underestimated. It does not measure loading; it measures the delay between an interaction and the next frame painted on screen. Above 500 ms, the page is classed as poor. On an advertising landing page, INP degrades for the same reason nearly every time: third-party scripts, consent banner included, occupying the main thread at the precise moment the visitor taps the button.
The Performance chapter of the Web Almanac 2025, built on Chrome UX Report data from July 2025, reports that 48% of mobile sites and 56% of desktop sites pass all three Core Web Vitals. A majority of mobile pages still sit below the bar. If you are starting a long way back, dedicated work on page speed will do more for you than a visual refresh.
Mobile is not a smaller desktop
Google explicitly recommends checking how the page adapts to mobile, noting that users there care even more about ease of navigation. The failure points are always the same: a phone number that is not tappable, a field that triggers the wrong keyboard, a button jammed against the edge of the screen, an interstitial covering the content on arrival.
One useful test costs nothing: open your own ad from your own phone, on mobile data, and try to complete the conversion. Past three screens and two minutes, the form is too long for an advertising intent.
Forms that are accessible, not just tidy
A badly built form loses conversions you have already paid for. The reference rules are the W3C's WCAG 2.2.
- Visible labels (3.3.2): a real
labeltied to each field, not placeholder text that vanishes as soon as typing starts. - Identify input purpose (1.3.5): a correct
autocompleteattribute lets the browser autofill, which cuts abandonment on mobile. - Target size (2.5.8, added in WCAG 2.2 at level AA): at least 24 by 24 CSS pixels for clickable elements, apart from the exceptions the criterion sets out.
- No redundant entry (3.3.7): do not ask again for information already given in the same process.
- Explicit error messages, next to the field concerned rather than in a block at the top.
This work goes well beyond advertising. In the European Union, Directive 2019/882 — the European Accessibility Act — has applied since 28 June 2025, and each country implements it through its own framework. Scope and exemptions depend on the size of the organisation and the type of service, so check with a legal adviser rather than assuming you are covered or exempt.
Proof, transparency and the legal basics
Transparency has long been part of what Google looks for: a visitor should understand who is selling, what, where and on what terms. Disclosure obligations themselves are national. In France, for instance, official guidance requires a professional website to show the company identity and address, its trade register number, a means of contact, the intra-EU VAT number and the host's details. Your own jurisdiction will have its own list; confirm it rather than copying another country's.
A standalone landing page still has to give access to that information, at minimum through footer links to the legal notices and the privacy policy. Then add what genuinely reassures: real lead times, the area you cover, a price or a range, photographs of your own work.
Measuring conversions with consent
Without reliable measurement, optimising a page is just opinion. But measurement has to respect consent. Google's EU user consent policy requires advertisers to obtain valid consent for cookies and for personal data used in ad personalisation, to keep a record of it, and to tell people how to withdraw it.
Technically, this runs through Consent Mode, which passes the consent state to Google tags. The developer documentation covers the ad_storage, analytics_storage, ad_user_data and ad_personalization parameters; the last two were added in November 2023 and belong in any current implementation. A default state, set before the tags fire, looks like this.
gtag('consent', 'default', {
'ad_storage': 'denied',
'ad_user_data': 'denied',
'ad_personalization': 'denied',
'analytics_storage': 'denied'
});Analytics sometimes sits under a narrower rule. The French data protection authority, the CNIL, allows an exemption from consent for audience measurement — French guidance, updated on 4 July 2025 — on strict conditions: measurement for the publisher alone, anonymous statistics, no cross-referencing and no tracking across sites. It does not cover advertising tracking, and other regulators take their own positions.
To offset the loss of signal, Google offers enhanced conversions, which send hashed first-party data using SHA-256. Useful, but it removes neither the consent requirement nor the duty to inform people. What matters more at the start is that your conversion definitions stay stable over time. That consistency is the core of serious traffic management.
Where to start
In this order, because each step conditions the next: confirm the destination complies with Google's rules; align the ad message with the page heading; fix speed and INP on mobile; simplify the form and make it accessible; publish your proof and legal information; then make measurement reliable, with consent. A UX audit focused on the conversion path settles the real question: repair the page you have, or rebuild it.
Common questions
What is landing page experience in Google Ads?
It is one of the three components of Quality Score, alongside expected click-through rate and ad relevance, and it indicates how relevant and useful your page is to people who click your ad. Google rates it above average, average or below average, against the other advertisers on the same search over the previous 90 days.
Can several ad groups point at the same page?
Technically yes, but it dilutes the perceived relevance of each group, and the wording of the ad no longer appears in the page heading. A page per main intent works better, even if you start with the two or three queries that consume the most budget.
Why is my INP poor when the page loads quickly?
INP measures the delay between an interaction and the next frame painted on screen, not loading. A page can appear fast and then freeze because third-party scripts are occupying the browser's main thread. Consent banners, tracking tools and chat widgets are the usual causes on an advertising page.
Does an advertising landing page need a consent banner?
Yes, as soon as you set advertising trackers or collect personal data for personalisation. Google's EU user consent policy requires valid consent, a record of it, and clear information on how to withdraw it. Narrow audience-measurement exemptions exist in some countries, but they do not cover advertising tracking.
Can an ad be disapproved because of its landing page?
Yes. Destination requirements reject pages that return an error, pages blocked by robots.txt, redirects to a domain other than the one displayed, disruptive pop-ups and pages with no original content. Check these before a campaign goes live.
Should I fix the page or rebuild it?
Fix when the structure is sound and the problems are identifiable: a mismatched heading, a slow script, an over-long form. Rebuild when one page is serving several unrelated intents, or the template blocks the changes needed.
