Frequently Asked Questions
Everything you need to know
Direct answers about the tool and how to get the most out of it.
Is the Lirotweb SEO Checker completely free?
Yes, the tool is 100% free and requires no sign-up or credit card. You can analyze any website as many times as you need at no cost. Lirotweb offers this tool as part of its commitment to the Spanish-speaking community of developers and digital marketing professionals.
How many pages can the crawler scan?
The crawler has no fixed limit. From the advanced configuration you can adjust the maximum number of URLs, the crawl depth (1 level, 2, 3, 5, 10 or unlimited) and the crawl speed in pages per second to avoid overloading your server.
What is the difference between on-page SEO and technical SEO audit?
On-page SEO analyzes the elements of each page that Google reads to understand what your content is about: titles, descriptions, headings, images and internal links. Technical SEO audit reviews the site infrastructure: page speed, redirects, 404 errors, SSL security, sitemap and robots.txt. The Lirotweb SEO Checker covers both areas in a single analysis.
Can I analyze a competitor's website?
Yes. You can enter any public URL to analyze it. It is especially useful to study what your competitors are doing well in SEO and detect opportunities for improvement in your own site. The crawler always respects the robots.txt file of the analyzed site.
What is AI/GEO Ready and why does it matter for SEO?
AI/GEO Ready is the optimization of your website to appear as a cited source in Google's generative results (AI Overviews), ChatGPT, Perplexity and other language models. The SEO Checker evaluates whether your site meets the accessibility, structured data and content quality requirements that LLMs use to select their sources.
How often should I analyze my website?
A complete SEO audit is recommended at least once a month, or after any major change: redesign, migration, new URL structure. For actively growing sites, a weekly analysis helps detect technical issues before they affect rankings.
Does the SEO Checker work with online stores and WordPress?
Yes. The tool analyzes any type of website regardless of the platform: WordPress, WooCommerce, Shopify, Prestashop, Wix, static sites or custom applications. The crawler acts like a Google bot and evaluates what the search engine actually sees.
