Where do these limits come from?
The character limits above come from each platform's own official ad specs and character-count documentation (Google Ads Help Center, Meta Business ad specs, X ad format specs, LinkedIn Marketing Solutions specs). Platforms can and do update these values over time, so always double-check the current official spec page before launching a large campaign.
Some of these limits are not a hard technical maximum. Meta's 125-character primary text and LinkedIn's 150-character introductory text are actually "recommended length before truncation" values — you can type more, but the platform will cut your text off behind a "See more" link. Since most users never click to expand, the important part of your message can end up unseen, which usually hurts engagement.
Google Ads' Responsive Search Ads feature lets you submit multiple headline and description variations for a single ad (up to 15 headlines and 4 descriptions), and Google's algorithm automatically mixes and tests those combinations. This tool helps you draft each individual variation within its field's character limit before submitting them.
When should you use Ad Character Counter?
The KEYDAL Ad Character Counter tool is a browser-based utility that developers, system administrators, SEO specialists and enterprise technology teams use in their daily operations. It requires no installation, is free, and produces results instantly. It is designed so local teams can run audits without connecting to server environments and run analyses without touching production.
Typical scenarios include: post-migration verification, comparing domain or hosting providers, diagnosing customer issues, security auditing (pre-pentest reconnaissance), root-cause analysis of email deliverability problems, validating CDN or proxy configuration, surfacing technical audit data for SEO teams, and rapid information gathering during incident response. You can copy results as text and share them or paste them into internal documentation.
The KEYDAL infrastructure team provides web hosting, VPS, dedicated server management, server hardening, DNS configuration and SSL/TLS deployment services from Türkiye. Beyond these tools, we deliver server setup and operations support across Hetzner, OVHcloud, Contabo, DigitalOcean and Turkish providers.
