What are the Google Ads headline and description character limits?

For Google responsive search ads, each headline field supports up to 30 characters and each description field supports up to 90 characters. Display path fields support up to 15 characters each. Because Google can combine assets in different orders, write every headline and description so it still makes sense independently.

What is the LinkedIn ad copy character limit?

LinkedIn does not have one universal ad copy limit: the accepted fields and visible length depend on the ad format, placement, and device. Use the selected LinkedIn format in the checker, treat hard limits as submission rules, and treat shorter display recommendations as guidance for avoiding truncation in the feed.

What is the difference between a hard character limit and a display recommendation?

A hard limit is enforced by the ad field and can prevent submission when exceeded. A display recommendation is a practical threshold for keeping important copy visible before truncation or a see-more control. Placement, device, language, and ad format can change how much recommended copy is visible.

What are the character limits for major ad platforms?

Google responsive search ads support headline fields up to 30 characters, description fields up to 90, and display path fields up to 15. Standard X posts support 280 characters. Meta, LinkedIn, and TikTok have format-specific rules and placement-dependent truncation, so the checker labels concise thresholds as display recommendations rather than universal hard limits.

How do I write effective ad copy within character limits?

Use abbreviations carefully, remove unnecessary words, focus on benefits not features, use numbers and specifics, include strong CTAs, test different lengths, and prioritize the most important message. Every character counts - cut filler words and be direct. Test shorter vs longer versions to see what performs best.

What happens if I exceed character limits?

Exceeding a hard field limit can block submission. Exceeding a display recommendation may still be accepted, but important words can move behind truncation or a see-more control. The checker identifies which type of threshold applies so you know whether the issue is delivery or presentation.

Should I use all available characters?

Not necessarily. Shorter, punchier copy often performs better than maxing out character limits. Test different lengths - sometimes a concise 20-character headline outperforms a 30-character one. Focus on impact and clarity rather than using every available character. However, having room allows for A/B testing variations.

How do I optimize ad copy for different platforms?

Keep the core promise consistent, then adapt the opening, proof, and call to action to the placement. Search ads should align closely with query intent. Feed ads need the main value in the first visible lines. Responsive formats need distinct assets that still make sense when platforms combine them in different orders.

Ad copy field guide

Google Ads and LinkedIn ad copy character limits

Google responsive search ads allow up to 30 characters per headline, 90 per description, and 15 per display path field. LinkedIn limits and visible copy vary by ad format and placement, so the checker separates hard field limits from practical display recommendations. After mechanical QA, make sure the first visible words identify the audience, outcome, and offer.

The handoff test

A campaign manager should be able to paste every asset into the platform without rewriting it, while a new buyer should understand the offer without reading every asset combination.

Google responsive search ads

30-character headlines, 90-character descriptions, and 15-character display path fields.

These are field limits. Google can combine assets in different orders, so each asset must make sense independently.

Meta feed placements

Primary text, headline, and description visibility changes by placement and device.

Treat concise thresholds as preview guidance, not a universal rejection limit across every Facebook and Instagram format.

LinkedIn single image ads

LinkedIn recommends up to 150 characters of introductory text and a 70-character headline.

Longer text can be accepted, but the first visible lines should carry the audience, problem, and value proposition.

X and TikTok

X standard posts use a 280-character limit; TikTok caption visibility varies by format and device.

URLs, full-width characters, and platform rendering can affect the final count or visible portion.

Lead with meaning

Put the offer, audience, or differentiator before secondary context. Truncation should not remove the reason to care.

Avoid interchangeable assets

Responsive systems need distinct headlines and descriptions. Repeating the same claim reduces useful combinations.

Match the destination

The ad promise, terminology, and call to action should continue on the landing page without a message gap.
