Frequently Asked Questions
Q. What does a meta tag checker analyze?
This tool checks the title tag (length, keyword placement), meta description (length, CTR effectiveness), Open Graph tags (og:title, og:description, og:image), Twitter Card tags, and canonical URL configuration.
Q. How long should a title tag be?
Google typically displays 50โ60 characters of the title tag in search results. Titles over 60 characters are truncated. Place your primary keyword at the beginning for maximum SEO impact.
Q. How long should a meta description be?
Meta descriptions are ideally 150โ160 characters. Google sometimes overwrites them with page content, but a well-written meta description improves CTR when it does appear. Include your target keyword and a call-to-action.
Q. What are Open Graph (OG) tags and why do they matter?
Open Graph tags define how your page appears when shared on Facebook, LinkedIn, KakaoTalk, and other social platforms. og:title, og:description, and og:image determine the share preview. Missing OG tags result in plain-text shares.
Q. Does a canonical tag help with duplicate content?
Yes. The canonical tag tells Google which URL is the "master" version when duplicate or near-duplicate content exists at multiple URLs. This prevents duplicate content penalties and consolidates PageRank.
Q. What is the ideal og:image size?
The recommended og:image size is 1200ร630 pixels (Facebook, Twitter) or 1200ร628 pixels (LinkedIn). Images smaller than 600ร315 pixels may not display as large previews on social platforms.

Expert Knowledge: Meta Tag Checker
Meta tags are the foundational layer of on-page SEO โ they're the first thing Google reads when crawling a page. While Google often rewrites title tags and meta descriptions based on query context, well-crafted originals increase the probability of your preferred text appearing in search results and can measurably improve organic CTR.
Open Graph protocol (developed by Facebook in 2010) has become the de facto standard for social sharing previews across all major platforms. Even non-Facebook platforms like LinkedIn, Slack, Discord, and KakaoTalk render OG tags. A compelling og:image โ minimum 1200ร630px, featuring bold text and a recognizable visual โ can dramatically increase click-through rates from social shares compared to pages with missing or generic OG images.
The canonical tag (rel="canonical") is one of the most commonly misimplemented SEO elements. Common mistakes include: pointing canonicals to redirect URLs (should point to the final destination), conflicting canonical and noindex tags on the same page, and missing canonicals on pagination pages (use rel="next"/"prev" or canonical to page 1). Auditing canonical implementation site-wide is often one of the highest-impact technical SEO improvements for content-heavy sites.
