Sitelink assets are one of the few Google Ads features that simultaneously increase click-through rate and provide a better experience to the buyer — and they cost nothing beyond the same CPC you were already paying. Research consistently shows that adding sitelinks increases CTR by 20-30% for well-structured campaigns. For B2B SaaS accounts where CPC inflation has pushed average keyword costs above $5-10 per click, extracting more value from each impression through higher CTR is a genuine CAC lever, not a cosmetic improvement.
The reason sitelinks underperform in many B2B SaaS accounts is not the format — it is the execution. Generic sitelinks ("About Us," "Contact," "Blog") do not help an enterprise buyer navigate to the next step in their evaluation. Sitelinks written specifically for the query intent, the buyer stage, and the decision criteria of B2B software buyers perform substantially better than repurposed navigation links. This guide covers the character limits you have to work with, which pages actually convert in B2B SaaS, and how to write link text that earns clicks from decision-makers rather than researchers. For the broader campaign structure context these sitelinks fit into, see our guide to B2B SaaS campaign structure by funnel intent tier.
Character limits: the exact numbers you need to know
The character limit for sitelink link text is 25 characters in most languages. This is the clickable anchor text — the only part that is always visible in every ad format. Each sitelink also supports two description lines at 35 characters each. These description lines appear when Google serves the expanded sitelink format, which happens on desktop in high-ranking ad positions. On mobile, description lines rarely show. The 25-character link text therefore needs to stand alone: it must communicate the destination clearly enough for a buyer to decide whether to click, without any help from the description.
Twenty-five characters is a tight constraint. To put it in perspective: "Free Trial — No Credit Card" is 29 characters. "Enterprise Pricing" is 18 characters and fits cleanly. "Security & Compliance" is 23 characters. "See How It Works" is 16. "Request a Demo" is 14. The constraint forces precision: you cannot use your sitelinks to explain anything. Each link text can only name the destination or the action clearly enough that the right buyer self-selects into clicking. This is actually an advantage when executed well — it eliminates the temptation to use marketing language and forces functional clarity. The description lines (35 characters each) are where you can add a single specific benefit or differentiator if the expanded format shows. Write them to complement the link text rather than repeat it: "Enterprise Pricing" + "Scales from 10 to 10,000 seats" is a complete thought that fits within both limits.
Which sitelinks convert for B2B SaaS buyers
The pages that drive clicks from B2B SaaS sitelinks fall into three categories: decision-enabling pages (pricing, comparison, security documentation), proof pages (case studies, customer logos, ROI calculator), and action pages (demo request, free trial, contact sales). Which category performs depends on the campaign type and the buyer's funnel stage. Brand campaigns typically see the highest CTR on pricing and demo request sitelinks, because a buyer searching your brand name is usually already considering your product and wants to take a next step. Non-branded category campaigns see higher CTR on comparison and proof pages, because buyers at the awareness stage are evaluating options and want evidence rather than pricing.
For most B2B SaaS accounts, the highest-performing sitelink set for non-brand campaigns includes: a pricing page (buyers always want to know cost), a page with customer logos or a case study in the buyer's industry vertical, a comparison page against the category leader, a security or compliance page for products where data handling is a buying criterion (which includes most B2B SaaS), and a demo or trial CTA. Avoid generic pages: "Features," "Solutions," and "Products" underperform because they do not signal what the buyer will find when they click. The same content labeled "See All Integrations," "Case Studies: HR SaaS," or "SOC 2 Compliance" will outperform the generic version because it answers a specific question in a buyer's mind.
Writing sitelink copy for enterprise decision-makers
Enterprise B2B buyers click on sitelinks for two reasons: they want to jump directly to the information that answers a specific evaluation question (pricing, compliance, implementation complexity), or they want a faster path to the action they were already planning to take (book a demo, start a trial). Sitelink copy that works is copy that makes the destination entirely predictable. The buyer should be able to read the link text and know exactly what page they will land on. Link text that does not match the landing page — "See How It Works" linking to a marketing page about the company rather than a product walkthrough — produces high initial clicks and low conversion rates, which hurts your Quality Score and wastes CPC on non-converting traffic.
There are three practical rules for B2B SaaS sitelink copy. First, use nouns over verbs where possible: "Enterprise Pricing" performs more consistently than "See Pricing" because it is clearer about what the destination is. Second, be specific over general: "Salesforce Integration" outperforms "Integrations" for buyers evaluating Salesforce compatibility. Third, match the sitelinks to the keywords in the campaign: a sitelink about compliance documentation should appear in campaigns where compliance queries are common, not applied account-wide to campaigns where buyers are searching for something entirely different. The campaign-level control lets you do this — use it. When you write description lines, the most effective approach is a single, specific, falsifiable claim: "Deployed in 48 hours," "No long-term contract," "Reviewed by 3,200 teams." Avoid superlatives and marketing language in the description lines — they reduce CTR in B2B contexts where buyers have developed strong filtering for promotional language.
Account-level vs campaign-level sitelinks
Google's asset hierarchy allows sitelinks to be set at the account, campaign, or ad-group level, with lower-level settings overriding higher-level ones. For B2B SaaS accounts, the most efficient structure is to build campaign-level sitelinks for each major campaign type — brand, competitor, category, and product-specific campaigns — rather than relying on account-level sitelinks. The reason is that a brand campaign and a non-branded competitor campaign serve buyers at completely different stages with completely different information needs. A buyer searching your brand name does not need to see a comparison page; they are already considering you. A buyer searching "[competitor] alternative" does not need to see your demo request — they need to see your comparison page and your case studies first.
Account-level sitelinks serve as a fallback for any campaign that does not have campaign-level sitelinks configured. The practical use for account-level sitelinks in B2B SaaS is to set a small set of genuinely universal pages — your main pricing page, your security overview, your demo request page — so that any campaign without its own sitelinks shows something relevant rather than nothing. Build campaign-level sitelinks for your top four or five campaigns by spend, then let the account-level set cover the tail. Ad-group-level sitelinks are rarely worth the maintenance cost for B2B SaaS accounts unless you have specific ad groups — a vertical-specific keyword group, for example — where the most relevant sitelinks are substantially different from the campaign-level set. For keyword research strategy that informs which campaigns need distinct sitelinks, see our Google Ads keyword research guide.
Dynamic sitelinks: when to enable, when to override
Google can generate automated sitelinks from your website content when dynamic sitelinks are enabled. These auto-generated sitelinks are created from pages that Google crawls on your domain and infers are relevant to the search query. For B2B SaaS accounts, dynamic sitelinks are worth enabling alongside manual sitelinks — they can surface pages that your manual set does not include, particularly for long-tail queries where a blog post or feature page on your site might be exactly what the buyer is looking for.
The risk with dynamic sitelinks is that Google may generate links to pages that are not optimized for conversion — blog posts, technical documentation, or support pages — rather than the decision-enabling pages that drive demo requests and trial signups. Monitor the automatic sitelinks report (found in the Assets section of your campaign) to see which auto-generated sitelinks are actually serving. If you see sitelinks pointing to high-CTR but low-conversion pages, you can add those pages to your campaign-level negative URL list to prevent them from generating sitelinks. The combination of well-built manual sitelinks at the campaign level and dynamic sitelinks enabled for coverage generally outperforms either alone. This connects to the broader question of how conversion tracking captures clicks from different entry points, covered in our guide to conversion tracking for SaaS.
Measuring and optimizing sitelink performance
Google Ads provides individual sitelink performance data in the Assets report under each campaign. The primary metric to track is sitelink click share — the percentage of ad clicks that came via each specific sitelink versus the main headline. Sitelinks with high click share are resonating with buyers at that campaign level; sitelinks with very low click share are either pointing to pages that buyers at that stage do not need, or using link text that does not signal a compelling destination clearly enough. The CTR shown in the sitelink asset report is the CTR for that sitelink specifically — compare it to the overall ad CTR to understand whether the sitelink is adding to or pulling from total click-through performance.
The optimization cycle for sitelinks is typically monthly or quarterly — not weekly. Unlike ad copy testing, sitelinks do not need continuous iteration; they need to be right for the buyer's evaluation stage and then left stable long enough to accumulate meaningful data. The exception is sitelinks for time-sensitive pages: if you have a sitelink pointing to a limited-availability offer, a webinar registration, or a pricing page during a promotional period, these need to be updated or removed when the underlying page changes. Stale sitelinks pointing to 404 pages or outdated offers harm both CTR and Quality Score. Build a monthly audit into your account maintenance cadence: check that every active sitelink resolves correctly and that the destination page matches the link text's promise.
