Short answer

A sitelink generator writes the extra links that show under a Google search ad, each with link text, two optional description lines and its own page URL. Link text has a 25-character limit, and each description line allows 35. An ad needs at least 2 sitelinks for any to show, and can show up to 6 on desktop and 8 on mobile.

How to use the Google Ads Sitelink Generator

Enter your website and press Find my pages to list its internal links, or paste page names and URLs yourself.
Add what you sell and any current offers, so the description lines can say something specific.
Generate 8 sitelinks and fix anything flagged, such as repeated link text or a URL on another domain.
Preview the ad, then copy the sitelinks, download the CSV or use the Google Ads Editor paste format.

What are the character limits for sitelinks?

Sitelinks, once called sitelink extensions, have up to four parts, each with its own limit. Spaces and punctuation count as characters.

Part	Limit	Rule
Link text	25 characters	12 in Chinese, Japanese and Korean. Must be different on every sitelink.
Description line 1	35 characters	Optional. If you fill it in, line 2 is required too.
Description line 2	35 characters	Optional, but only together with line 1.
Final URL	One per sitelink	Same domain as the ad, with limited exceptions.

The link text limit is on Google's sitelink assets help page, the 35-character description lines are in the Google Ads API asset definitions, and the rule that filling in line 1 makes line 2 required is in the Search Ads 360 sitelink settings. To test sitelinks you wrote yourself, paste them into the Google Ads Character Limit Checker.

How many sitelinks should you add?

Your ad needs at least 2 sitelinks before any of them can appear. On desktop, Google can show up to 6, stacked or side by side across one or 2 lines. On mobile, it can show up to 8 side by side in a carousel. Video and Demand Gen campaigns show up to 4.

Google's Ad Strength guidance asks for at least 6 sitelinks across the ad group, campaign and account, and suggests opting in to dynamic sitelinks. The generator writes 8, enough to fill the mobile carousel.

You can add sitelinks at the account, campaign or ad group level, and sitelinks from a higher level can serve alongside those from a lower one. Keep general pages such as Contact Us at account level, and service pages in the ad groups they match. Clicks on sitelinks are paid clicks, and Google charges at most 2 clicks per ad impression.

What makes a good sitelink?

A good sitelink leads to one specific page and says plainly what is on it. The description lines add a detail that helps someone choose. Here is a set for a fictional plumbing company:

Link text	Description line 1	Description line 2
Drain Cleaning	Kitchen, bath and main lines	Camera inspection on request
Water Heater Repair	Tank and tankless units	Repair or replace, your choice
Book Online	Choose a time that suits you	Confirmation by text or email
Areas We Serve	See the towns we cover	Check your ZIP code on the map

Every link text is different, and each pair of lines is about its own page. Skip vague labels like "Learn More" or "Click Here": Google's style and spelling policy names "click here" as an example of a generic call to action.

Which sitelink rules does Google enforce?

Google's sitelink asset requirements are short. These are the ones that catch people out:

No reused link text. In Google's words, "Reusing link text is not allowed even if each sitelink points to a different destination."
No attention-grabbing symbols. Exclamation marks and arrows such as ► are out, in the link text and in the descriptions.
Same domain as the ad. Links should point to the domain of the ad's final URL. Google allows a short list of third-party sites in limited cases, and then the link text must describe the destination and include its full domain.
No repeats of your ad text. Google's repetition policy covers assets that repeat text already in the ad, so give your sitelinks pages and details the headlines do not already cover.

The generator checks the first three rules and the description pairs for you. Its flags are warnings, and Google's review makes the decision.

How do you add the sitelinks to Google Ads?

Type a few straight into Google Ads, or add many at once in Google Ads Editor. The Editor paste format gives you four columns: Link text, Description line 1, Description line 2 and Final URL. Google's Editor sitelink guide also requires a Campaign column, plus an Ad group column for ad group sitelinks, so add those before you import with Account > Import > Paste text.

Common sitelink mistakes

Several sitelinks pointing at the home page. A sitelink earns its click when it opens the page its text promises. If that page does not exist yet, leave the sitelink out.
Only one description line. Write both lines or neither.
Descriptions that fit any page. "Quality work you can trust" says nothing; "Tank and tankless units" tells people what they will find.
Stopping at the minimum. Two sitelinks let the feature switch on, but Ad Strength looks for at least 6.
Skipping the preview. Load your ad into the Google Ads Preview Tool to see the sitelinks on mobile and desktop, then add short selling points with the Callout Generator.

Frequently asked questions

How many characters can a sitelink have?

Sitelink link text can be up to 25 characters, or 12 in a double-width language like Chinese, Japanese or Korean. Each of the two optional description lines can be up to 35 characters. Spaces and punctuation count toward every limit, so a line that looks short can still run over.

How many sitelinks should I add to a Google Ads campaign?

Add at least 6. Google needs at least 2 sitelinks before any can show, but its Ad Strength guidance asks for 6 or more across the ad group, campaign and account. Ads can show up to 6 sitelinks on desktop and up to 8 on mobile, so a set of 8 covers both.

Do sitelinks need descriptions?

No, sitelink descriptions are optional. If you add them, fill in both lines: Google requires description line 2 whenever description line 1 has text. Each line can be up to 35 characters. Use the lines for a detail about the page, such as what it covers or how to book, rather than repeating the link text.

Can a sitelink go to a different website?

Usually not. Sitelinks should use the same domain as the ad's final URL. Google allows links to a short list of third-party sites in limited cases, and then the link text must describe where the link goes and include the full domain. A link to any other outside site breaks Google's sitelink requirements.

Can two sitelinks have the same text?

No. Google does not allow the same link text on more than one sitelink, even when each one points to a different page. Give every sitelink a label that names its own page, such as "Drain Cleaning" and "Sewer Line Repair", rather than two links that both say "Services".

Do you pay for clicks on sitelinks?

Yes, a click on a sitelink is a paid click on your ad. Google charges for at most 2 clicks per ad impression, so a single showing of your ad never costs more than 2 clicks, however many of its links someone opens. Make sure each sitelink page is as ready to convert as your main landing page.
