# Screaming Frog

> Screaming Frog SEO Spider is a desktop tool for technical SEO audits that crawls a website like a search engine bot, collecting data on URLs, status codes, meta tags and link structure.

**Screaming Frog SEO Spider** is a desktop tool for technical SEO audits that works like a [crawler](https://nodea.io/en/glossary/crawler) — it visits a site's pages on its own, following links exactly as a search engine bot would. It presents the gathered data in tables, surfacing technical problems that stay invisible during ordinary browsing.

## How Screaming Frog works

You run the program on your own computer and point it at a starting URL. Screaming Frog fetches the page, extracts every link and visits each subsequent address in turn, building a map of the entire site. For each URL it collects a set of parameters: the HTTP response code (200, 301, 404, 500), the [title](https://nodea.io/en/glossary/title-tag) and meta description with their lengths, H1–H2 headings, canonical attributes, *robots* directives, image alt attributes, and the number of internal and outbound links.

The tool respects robots.txt, can render JavaScript, integrates with Google Analytics and Search Console, and generates XML sitemaps. The free version caps the number of URLs crawled; the paid licence removes the limit and unlocks advanced features such as scheduled crawls and custom data extraction.

## Practical application

Screaming Frog is a staple of [on-page SEO](https://nodea.io/en/glossary/on-page-seo) auditing. A single crawl surfaces broken links and 404s, detects duplicate or missing titles and descriptions, locates redirect chains, orphan pages with no internal links, and images without alt text. Specialists use it during site migrations (comparing URLs before and after), for information-architecture analysis, and to verify that pages meant for [indexing](https://nodea.io/en/glossary/page-indexing) are not accidentally blocked. A comparable competitor in the same role is [Sitebulb](https://nodea.io/en/glossary/sitebulb), which puts more emphasis on visualizing the results.

### How does Screaming Frog differ from Google Search Console?

Screaming Frog is a crawler you run locally that scans a site on demand and shows its technical state from the inside. Search Console is Google's free tool that presents data from the search engine's perspective — real indexing, traffic and errors as seen by Googlebot. In an audit the two complement each other.
