HTML Analyzer: A tool to easily audit urls

HTML Analyzer is a tool I have developed as GPT in ChatGPT, designed especially for digital design and marketing professionals who, like me, work daily with web pages, but want to give them a more technical review and support for their analysis.

For years, I have been very involved in web projects, and I have found myself many times reviewing source code to make sure that everything is correct: header structure, well-used labels, metadata SEO, basic accessibilityetc. The problem is that they are technical aspects that can easily be escaped from us, especially when you are not a developer.

That's why I thought of creating a simple and clear tool that would allow audit a web directly from the HTMLwith a logic adapted to those who design or manage digital projects.

What is the HTML Analyzer for?

The tool is designed to analyze, step by step, the key elements that affect the SEO on-page, at Web accessibility and structure of a well-built page. All with a modular, professional and easy to understand approach.

It works as an assistant within ChatGPT, which directly analyzes the HTML you hit in the chat. First ask you to copy the source code from your website, then you can choose which area to analyze or ask for the full report divided into 10 modules.

The analysis is based on 10 key areas that I defined myself based on my experience working with websites:

• Structure of content and hierarchy
• Metadata and SEO on-page
• Internal and external links
• Basic accessibility (WCAG 2.1)
• Forms and inputs
• Navigation and interface structure
• Resource burden and performance
• Microdata and enriched data
• Language and legibility
• Visual identity and non-visual resources

In addition, at the end of the analysis, it provides a summary with customized conclusions and recommendations to improve each aspect.

How does it work?

One of the advantages of HTML Analyzer You don't need to install anything, or register, or have advanced technical knowledge. It works within ChatGPT as a conversational assistant, so just follow a few simple steps:

1. Open the website you want to analyze. It can be one of yours, one of a client, or any place you want to audition.
2. Right-click an empty area of the page and select "View source code of the page" (in Chrome it appears as "View Page Source"). A new tab will be opened with the full HTML code of the web.
3. Select all content with Ctrl + A (or Cmd + A on Mac), copy with Ctrl + C (or Cmd + C), and returns to the GPT chat to stick it (Ctrl + V).
4. The assistant will ask you what you want to analyze first: you can choose one of the 10 key areas (SEO, accessibility, content structure...) or request a complete module analysis per module.
5. From there, the GPT will exclusively analyze the content of the HTML you have given it. Do not invent or fill anything, simply interpret what you see, detect what is missing and explain how to improve each section.

In case the HTML is very extensive, you can also save the file as .html and attach it directly in the conversation. This ensures that the analysis is complete and that no fragment of the document is cut. All the conclusions it draws, as well as the information it gives you, are extracted from different sources, books and own knowledge, so that it can give the user a proven and real information.

Why I thought it necessary to create it

What I was looking for was a way of fast, structured and clear check whether a page is well built. Over the years, working as UX / IU designer and branding and digital strategy consultantI have had to review many websites: from simple landings to complex online shops or multilingual corporate portals. In all of them, there is a common point that I am always concerned about: is the base HTML well built?

Many times we consider that the code is fine just because visually everything "works," but a quick review is enough to see that key labels are missing, title hierarchies are broken, accessibility roles are not used, or there are basic errors of SEO on-page.

And the truth is, although I understand a lot of HTML out of professional need, I'm not a developer.. That makes certain technical audits take me longer than I should or depends on external plugins, browser extensions or tools that don't always fit what I'm looking for.

That's why I decided to create this tool myself.: an assistant in ChatGPT that It will help me review any HTML as if I had a technical expert next door. But, yes, I would speak in my language: clear, direct and without excess technicalities. The idea was to be able to ask things like "are H1 and H2 well put?," "does this form have its label label well?," or "are there microdata on the page?," and that the answer was structured and understandable.

Over time I realized that this tool not only helped me, but could be as useful to other people who are in the digital world but they don't program on their day-to-day: web designers, consultants SEO, content creators, marketing professionals... all profiles that need to validate the technical quality of a web without opening DevTools or using command lines.

In short, I created it out of pure practical need., and I'm delighted to have come up with a solution that comes with me every day and that can now help you too.
