How Our Tech Stack Detector Works
Enter Any Website URL
Simply paste the URL of any website you want to analyze — your competitor, a prospect, or any site you're curious about.
4-Layer Deep Scan
Our engine fetches the URL and analyzes HTTP response headers, raw HTML source code, embedded JavaScript/CSS patterns, and URL path structures simultaneously.
Signal Aggregation & Scoring
Each detected pattern (called a signal) is matched against our database of 100+ technologies. Multiple signals for the same technology increase its confidence score.
Actionable Intelligence Report
Get a structured report showing every detected technology, its version (when available), confidence score, and which signals triggered the detection.
How to Use This Tool Effectively
Actionable SEO advice to get the most out of every analysis
Start With Your Competitors
Run your top 3 competitors through this tool first. Understanding their structure, keywords, and technical issues reveals exactly where you can outrank them.
Run Monthly Audits
SEO is not a one-time task. Schedule monthly checks to catch new issues before Google penalizes them. Consistent analysis beats one big yearly audit every time.
Fix High-Impact Issues First
Not all errors are equal. Prioritize: broken crawl paths → missing meta titles → slow load times → thin content. This order maximizes ranking gains per hour spent.
Internal Links Are Free PageRank
Every internal link passes authority between your pages. Use the Internal Link Finder to ensure your most important pages receive the most internal links.
Page Speed Directly Affects Rankings
Google's Core Web Vitals are a confirmed ranking factor. Pages loading under 2.5 seconds see significantly higher rankings and 40% lower bounce rates than slow pages.
Keep Your Sitemap Clean
Your sitemap tells Google what to index. Remove redirect chains, 404s, and noindex pages from it. A clean sitemap = faster, more complete indexation of good content.
