SEO calculators
Structured data and on-page SEO helpers, private and instant in your browser.
These tools handle the technical and on-page SEO tasks that require precise measurement or structured output. The SERP snippet simulator renders desktop and mobile Google result previews with pixel-accurate truncation counters for title and description so you can see exactly how a page will appear in search results before publishing. The title tag pixel width tester uses the actual Google font metrics to flag whether a title fits the desktop and mobile display thresholds, not character count estimates.
The meta tag generator produces ready-to-paste HTML for title, description, canonical, robots, Open Graph, and Twitter Card tags from a single form. The Open Graph card preview renders how a URL will appear when shared to Facebook, LinkedIn, WhatsApp, and Slack. The internal link map visualizer builds a force-directed graph from a CSV export of your site structure to identify orphaned pages and weak hub connections. The robots.txt tester validates allow and disallow rules against specific URL patterns without deploying a file change.
