Google Ads sitelink assets enforce strict maximum limits: 25 characters for Sitelink Text (Headline) and 35 characters each for Description Line 1 and Description Line 2 (CJK languages allow 12 and 17 double-width characters respectively). On mobile screens, link text exceeding 18–20 characters risks ellipsis truncation. Minimum 2 sitelinks are required for mobile display, and 2 to 6 for desktop search ads.

1. Sitelink Asset Specifications Matrix
Sitelink assets (formerly sitelink extensions) are among the most powerful ad enhancements in Google Ads, providing additional pathways into your sales funnel and expanding your ad's vertical real estate on SERPs. However, Google enforces strict character counting algorithms across all supported languages.
Below are the verified character limits for Google Ads sitelinks:
Google Ads enforces a strict maximum limit of 25 characters for Sitelink Text (Headline) and 35 characters each for Description Line 1 and Description Line 2. To prevent ellipsis truncation on mobile devices, keep headlines within the 18–20 character sweet spot.
| Asset Component | Max Characters (Latin) | Max Characters (CJK) | Recommended Sweet Spot | Status |
|---|---|---|---|---|
| Sitelink Text (Headline) | 25 Characters | 12 Characters | 18–20 Characters | Mandatory |
| Description Line 1 | 35 Characters | 17 Characters | 30–35 Characters | Recommended |
| Description Line 2 | 35 Characters | 17 Characters | 30–35 Characters | Recommended |
| Final URL | 2,048 Characters | 2,048 Characters | Standard Valid URL | Mandatory |

*Note on Double-Width Languages: Google Ads counts Chinese, Japanese, and Korean (CJK) characters as 2 characters toward the limit due to full-width character rendering in standard typography engines.
2. Desktop vs Mobile Sitelink Formats
How your sitelinks render depends heavily on the user's device screen width and your Ad Rank:
- Shows 2 to 6 sitelinks simultaneously.
- Can display in an expanded 2-column or 3-column layout complete with both description lines when Ad Rank is high.
- May also display in a single condensed row of hyperlinks under the main ad copy.
- Shows up to 8 sitelinks arranged in a horizontal scrollable card or carousel layout.
- Descriptions are frequently suppressed on mobile to save vertical viewport space.
- Text exceeding 18–20 characters is frequently cut off with an ellipsis (…), making the headline unreadable.
3. The Two-Line Rule & Description Drops
Although Google Ads marks Description Line 1 and Description Line 2 as "Optional" in the campaign interface, PPC practitioners must understand the Two-Line All-or-Nothing Rule:
Google Ads will never render only one description line. If you fill in Description Line 1 but leave Description Line 2 blank, Google will suppress your description completely, serving only the 25-character sitelink title. To qualify for the expanded 2-line desktop format, you must complete both description lines with meaningful, policy-compliant copy.
Furthermore, adding descriptions does not guarantee they will appear on every impression. Google Ads dynamically selects whether to display descriptions based on Ad Rank, ad position, competing ads on the SERP, and expected click-through rate (eCTR) calculations.
4. Final URL Rules & Disapproval Traps
Sitelink asset disapprovals are among the most common account issues. Ensure your links adhere to these foundational URL requirements:
Two sitelinks in the same ad group or campaign cannot lead to the exact same webpage. Each sitelink must direct to unique content (e.g. /pricing/, /contact/, /case-studies/).
For single-page sites, you can use distinct URL anchor hashes (e.g. example.com/#pricing and example.com/#reviews) provided each hash jumps to distinctly different content sections.
The domain of every sitelink Final URL must exactly match the domain of your main ad's Final URL. You cannot send sitelink clicks to third-party subdomains or external partner websites.
5. Sitelink Description Character Counter Workflow
When writing dozens of sitelinks across broad PPC accounts, relying on manual character counts leads to rejected uploads or unexpected truncation. Follow this structured production workflow:
- Draft for Mobile First (18–20 Chars): Keep your Sitelink Headline concise and punchy. Aim for 18 to 20 characters so your link renders completely without ellipsis cutoffs on mobile screens.
- Complete Both 35-Character Descriptions: Use Description 1 to highlight a primary feature (e.g., "Compare Plans & Transparent Rates" – 34 chars) and Description 2 for an active call to action (e.g., "Sign Up Today for a Free 14-Day Trial" – 35 chars).
- Verify via Free Interactive Counter: Paste your copy into our live Google Ads Character Counter to catch length overages and double-width CJK characters before exporting to Google Ads Editor.
- Implement at Account, Campaign, or Ad Group Level: Attach broad sitelinks (e.g. Contact Us, About Us) at the Account level, and product-specific sitelinks at the Campaign or Ad Group level for hyper-relevant messaging.
6. Google Ads Sitelink Policy Do's & Don'ts
- Title Case capitalization (e.g. "Browse Winter Jackets").
- Action-oriented verbs (e.g. "Book", "Schedule", "Explore", "Download").
- Specific product categories, store locators, or transparent pricing pages.
- Adding at least 4 active sitelinks per campaign (Google recommends 4+).
- Exclamation marks (!) anywhere in sitelink text or descriptions.
- Gimmicky capitalization (e.g. "F-R-E-E S-H-I-P-P-I-N-G").
- Identical sitelink text repeated across multiple links in the same ad.
- Emojis, emoticons, or non-standard symbols in link copy.

What is the exact character limit for Google Ads sitelinks?
Google Ads sitelinks enforce a maximum of 25 characters for Sitelink Text (Headline) and 35 characters each for Description Line 1 and Description Line 2 in English and Latin alphabets. For double-width character languages like Japanese, Chinese, and Korean (CJK), the limits are 12 characters for headlines and 17 characters for descriptions.
How many sitelinks should I add to a Google Ads campaign?
Google recommends adding at least 4 active sitelinks at the campaign or ad group level. A minimum of 2 sitelinks is required for them to serve on mobile devices, and 2 to 6 sitelinks can appear simultaneously on desktop search ads. Having 4 to 8 active sitelinks gives Google's AI auction algorithm sufficient inventory to optimize for user intent.
Do sitelink descriptions always show in search results?
No. Descriptions only render when your ad achieves sufficient Ad Rank and ad position (typically top position 1 or 2). Furthermore, Google enforces the "all-or-nothing" rule: if you provide Description 1 but leave Description 2 blank, Google suppresses descriptions entirely. On mobile devices, Google often hides descriptions to save viewport space.
Can two sitelinks go to the same webpage URL?
No. Google Ads policy strictly forbids multiple sitelinks within the same campaign or ad group pointing to the identical destination URL. Each sitelink must direct users to unique content. For single-page sites, distinct anchor fragment hashes (e.g. #features vs #pricing) are acceptable if they navigate to distinct sections.
Can I use exclamation marks in Google Ads sitelinks?
No. Google Ads Editorial Guidelines strictly prohibit exclamation marks in sitelink link text and descriptions to prevent spammy or sensationalized advertising. Question marks, periods, commas, and hyphens are permitted when used grammatically.
