FOR IMMEDIATE RELEASE
LondonWebFactory.Com Ltd Releases SEO Web Spider – A Professional-Grade Website Crawler for Windows and macOS
New desktop SEO application offers unlimited website crawling, comprehensive technical SEO analysis and a free edition without an artificial URL limit.
LONDON, UK — Wed 16 Sep 2026, 12:37 UTC — LondonWebFactory.Com Ltd has released SEO Web Spider, a professional desktop website crawler designed to help SEO professionals, developers, digital agencies and website owners identify technical and on-page SEO issues across websites of virtually any size.
Available for Windows and macOS, SEO Web Spider crawls websites and analyses their pages to provide a detailed picture of site structure and the information search engines encounter when visiting them.
The software has been developed around a straightforward principle: professional website analysis shouldn't stop simply because a website exceeds an arbitrary URL limit.
Both the Free and Pro editions of SEO Web Spider therefore offer unlimited crawling. Practical crawl capacity is determined by the user's computer, the website being analysed and the selected crawl configuration rather than an artificial software limit.
Comprehensive SEO Website Analysis
SEO Web Spider extracts and analyses the information SEO professionals routinely need when auditing websites.
This includes page titles, meta descriptions, headings, internal and external links, HTTP status codes and indexability information. The crawler follows links throughout a website to build a detailed picture of its structure and identify potential technical and on-page SEO problems.
Users can quickly investigate issues including missing or duplicate page titles and descriptions, broken links, redirects and pages that may not be available for search-engine indexing.
SEO Web Spider also reports the reason why a URL may not be indexable, helping users understand whether an issue relates to robots.txt, page-level directives or another technical restriction.
A Full DOM Website Crawler
SEO Web Spider is a full DOM crawler designed to analyse modern websites and provide SEO professionals with the information they need to investigate individual pages as well as site-wide problems.
It has been built to handle everything from small business websites containing a few dozen pages to large websites containing hundreds of thousands of URLs.
Users can control how aggressively a website is crawled by selecting different performance modes.
Gentle mode uses a single crawler for sites where minimal server load is desirable. Balanced mode provides increased performance for everyday SEO work, while Fast mode can run up to 12 crawlers concurrently to analyse large websites considerably more quickly.
SEO Web Spider also respects robots.txt instructions by default, supporting responsible crawling while still providing the flexibility required for authorised technical SEO work.
Free and Pro Editions
The Free edition of SEO Web Spider includes unlimited crawling and professional-grade SEO analysis, making it useful for website owners, students, developers and SEO professionals without requiring a subscription or imposing a small URL allowance.
For users who require additional professional workflow and reporting capabilities, SEO Web Spider Pro adds faster crawling and a range of productivity tools.
Pro features include CSV export, URL-list importing, the ability to save and reopen crawls, and tools for creating, saving, reopening and sharing custom SEO reports.
Pro users can also take advantage of the application's fastest crawling capabilities, with support for up to 12 concurrent crawlers.
Rather than requiring an ongoing monthly or annual subscription, SEO Web Spider Pro is available for a one-off lifetime price of $79.
Developed from Real-World SEO Experience
SEO Web Spider has been developed by LondonWebFactory.Com Ltd, a UK web development and digital marketing company providing website development, search engine optimisation, PPC management and professional SEO training.
The software grew out of the practical requirements of auditing websites and teaching technical SEO.
“Our aim was to build the website crawler we actually wanted to use,” said Adrian Smith of LondonWebFactory.Com Ltd.
“We didn't want somebody analysing a website to reach an arbitrary URL limit and discover that they had only examined part of it. That's why the Free edition remains a genuinely useful professional crawler. Pro is about giving regular users more speed, exporting, saved crawls and advanced reporting rather than simply unlocking the ability to crawl a complete website.”
Making Technical SEO Easier to Understand
SEO Web Spider has also been designed to help users understand the information behind technical SEO issues rather than simply presenting an automated SEO score.
By exposing page data, links, status codes, indexability information and other technical details, users can investigate individual problems and understand how different parts of a website relate to one another.
This makes the application suitable not only for experienced SEO professionals and agencies but also for developers, website owners and people learning technical SEO.
As a desktop application, crawling takes place directly from the user's computer, providing an alternative to cloud-based SEO platforms and subscription services.
SEO Web Spider is available for Windows and macOS, with Free and Pro editions.
