Frequently Asked Questions
What does the Meta Tag Generator produce?
It generates the full set of HTML meta tags needed for SEO and social sharing: title, description, canonical URL, robots directive, Open Graph tags (og:title, og:description, og:image, og:url), and Twitter Card tags. Copy the output and paste it into your page's <head> section.
How does the OG Image Preview work?
Enter any URL and the tool fetches the page's Open Graph tags and renders a preview of how the link will appear when shared on Facebook, Twitter/X, LinkedIn, and iMessage. This is useful for catching missing or incorrectly sized OG images before publishing.
Should I allow or block AI crawlers in robots.txt?
Allowing AI crawlers (GPTBot, ClaudeBot, PerplexityBot) means your content can appear in AI-powered search results. Blocking them prevents use of your content for AI training. Most websites benefit from allowing these crawlers. The Robots.txt Generator includes dedicated toggles for each AI crawler.
