Engineering-grade technical SEO tools. 100% free.
SEO Micro-Tools was built to solve a simple frustration: most SEO tools either hide basic technical checks behind expensive subscriptions, require bloated registrations, or rely on outdated heuristics like 60-character title counts rather than real search-engine rendering realities.
Our Core Principles
Pixel-Width Precision
Google desktop search results do not truncate titles at 60 characters—they truncate at approximately 580 to 600 pixels. Our tools simulate actual Arial advance widths so you see what users will actually see.
Strict Web Standards
We adhere strictly to the RFC 9309 Robots Exclusion Protocol, sitemaps.org XML schema, and Google Search Central specifications. We explain exactly which directive caused a rule to match.
No Artificial Paywalls
Every tool on this website is free to use without requiring an account, email, or credit card. We believe individual technical diagnostic tools should be accessible to every webmaster worldwide.
Safe Server-Side Fetching
Because modern browsers block cross-origin requests, our tools execute on isolated, SSRF-protected servers that never hit private IP ranges and cache results politely to avoid overburdening your infrastructure.
How We Support This Project
To keep these micro-tools completely free for all users, we display non-intrusive advertisements in fixed-height layout slots that never cause Cumulative Layout Shift (CLS). We never sell your diagnostic queries or collect sensitive browsing data.
