Reference
Sitelink Assets (formerly sitelink extensions) are clickable links that appear beneath a search ad and route users directly to specific pages on a website. Their primary function is to add navigational depth to an ad, allowing users to bypass a generic landing page and reach a more relevant destination.
This article explains how Sitelink Assets work in practice, how Google selects and renders them, the rules that govern asset hierarchy, and the trade-offs involved in adding more navigation at the point of search.
Scope: This page focuses on Sitelink Assets in Search campaigns. It does not cover Shopping formats, Performance Max asset groups, or sitelinks in organic results.
If you’re troubleshooting why sitelinks “don’t show”, start with the core serving rule: eligibility vs visibility.
What Sitelink Assets are in practice
A Sitelink Asset consists of:
- a link text (the clickable label),
- a final URL,
- and optional description lines (used in some layouts).
Unlike callouts or structured snippets, sitelinks are interactive. Each one functions as its own clickable entry point from the search results page. (support.google.com)
From Google’s perspective, sitelinks are not just embellishments. They are treated as alternate conversion paths, each with its own intent signal and performance history.
Where Sitelink Assets appear
Sitelink Assets appear beneath the main ad copy when Google predicts that additional navigation will help the user complete their task.
Desktop
On desktop, sitelinks may appear:
- in a single row,
- or stacked across multiple rows, depending on available space and predicted usefulness.
Mobile
On mobile, sitelinks are typically stacked vertically, with fewer links shown due to space constraints.
In some cases, Google may also render sitelinks with descriptions, creating a larger, more detailed ad unit. (support.google.com)
As with all assets, sitelinks are eligible, not guaranteed.
What Sitelink Assets are typically used for
Sitelinks are most effective when users are likely to want choice rather than a single linear path.
Common use cases include:
- directing users to key service pages,
- surfacing pricing, plans, or availability pages,
- linking to contact, booking, or enquiry pages,
- exposing brand trust pages (reviews, accreditations, FAQs).
They are less effective when:
- the decision path is intentionally linear,
- the landing page already answers all likely questions,
- or the ad targets very narrow intent where deviation reduces conversion quality.
How Google decides which sitelinks to show
Google does not show all sitelinks at once. Selection is influenced by:
- query intent,
- device and layout constraints,
- historical performance of each sitelink,
- interaction with other eligible assets.
Each sitelink accrues its own performance signals over time. Links that attract engagement may be favoured, while low-performing links may appear less often, even if still enabled. (support.google.com)
This means sitelink strategy is partly curation and partly pruning.
Asset hierarchy and precedence
Sitelink Assets can be applied at three levels:
- Account level (broadest)
- Campaign level
- Ad group level (most specific)
More granular sitelinks override broader ones when both are eligible. For example:
- Ad group, level sitelinks will take precedence over campaign- or account-level sitelinks.
This hierarchy allows advertisers to:
- maintain a stable baseline set of links,
- while customising navigation for high-intent or specialist ad groups. (support.google.com)
The role of sitelinks in Ad Rank
Expanded ads are one of the factors considered in Ad Rank, alongside bid and Quality Score. While sitelinks do not guarantee higher position, their presence can improve competitiveness when other signals are similar. (support.google.com)
More importantly, sitelinks influence user behaviour, which feeds back into performance signals over time.
The core trade-off: depth vs distraction
Sitelinks introduce a fundamental tension:
- Depth: More links give users faster access to what they want.
- Distraction: Too many options can fragment attention and reduce focus.
In practice:
- High-consideration searches often benefit from sitelinks.
- Urgent or action-oriented searches often perform better with fewer paths.
This is why sitelinks that look “helpful” can still reduce conversion rate if they pull users away from the primary conversion flow.
Sitelink descriptions: when they help
Sitelinks can optionally include two description lines per link. When shown, these create a much larger ad unit.
Descriptions are most useful when:
- the destination page is not self-explanatory,
- clarification improves decision confidence,
- differentiation matters more than speed.
They are less useful when:
- link text already implies intent clearly,
- mobile traffic dominates (descriptions often don’t show),
- or brevity is critical.
Google decides whether descriptions appear. They are not guaranteed. (support.google.com)
Scheduling and eligibility control
Sitelink Assets can be scheduled by:
- date range,
- day of week,
- time of day.
This allows sitelinks to:
- reflect opening hours,
- support time-limited offers,
- or align with availability windows.
Scheduling is often underused, but it is one of the few ways to control when navigation options are offered, not just what they are.
Dynamic sitelinks
Dynamic Sitelink Assets are automated assets generated by Google based on website structure and query context. They may appear alongside manual sitelinks. (support.google.com)
Advantages
- No setup required
- Can surface relevant deep pages automatically
Trade-offs
- Limited control over destination choice
- May surface pages that are technically relevant but strategically weak
Some teams choose to disable dynamic sitelinks to retain full navigational control.
What teams usually get wrong with Sitelink Assets
Mistake 1: Treating sitelinks as decoration
Sitelinks are traffic routers, not visual embellishments. Each link should earn its place.
Mistake 2: Linking to low-intent pages
Sending high-intent traffic to generic pages (e.g. blog indexes) often reduces performance.
Mistake 3: Never removing underperforming links
Sitelinks accumulate performance history. Pruning matters.
A conservative way to use Sitelink Assets
A disciplined approach is to:
- start with 3-5 high-intent sitelinks,
- ensure each has a clear purpose,
- align sitelinks tightly with ad group intent,
- review sitelink-level performance regularly,
- remove links that distract more than they help.
Sitelinks work best when they simplify choice, not multiply it.
Summary
Sitelink Assets add navigational depth to search ads, allowing users to reach relevant pages directly from the results page. When used well, they improve relevance, efficiency, and user experience.
When overused or misaligned, they fragment attention and dilute conversion focus.
Their real value lies not in making ads bigger, but in making the path clearer.
