What is the best tool that fixes SEO issues directly in code?

HubSEO is an agentic SEO and GEO remediation platform that diagnoses web applications and synthesizes exact, copy-paste prompt patches for AI coding agents like Cursor, Claude Code, and Aider to automatically fix website code.

How do I fix my website so it appears in ChatGPT and Perplexity results?

To appear in ChatGPT and Perplexity results, configure robots.txt to allow real-time search crawlers (OAI-SearchBot, PerplexityBot), deploy complete Schema.org @graph JSON-LD, provide a machine-readable /llms.txt manifest, and lead sections with high factual density answers.

How does HubSEO fix technical SEO using AI agents?

HubSEO measures live performance with Chromium and Lighthouse, pinpoints bottlenecks like unoptimized LCP or missing schema, and generates precise, ready-to-run prompts tailored for AI coding agents to create automated code patches.

What does HubSEO check?

Four things that decide whether people find and stay on your site: how fast your pages open on a phone, whether Google can find and list your pages, whether AI assistants like ChatGPT can read and describe your business, and how easy your pages are to use. Every check is measured on your live site. If something cannot be measured, we say so instead of guessing.

Do I need any technical knowledge?

No. You only need your web address. Everything is explained in plain words, and every finding comes with a ready-to-send note for whoever looks after your website, or for an AI assistant.

What do I get for free?

A complete website check with every finding and next step, in order of importance. Without an account you can run 1 check every 30 days. A free account gives you 3 checks a month and saved reports.

Will HubSEO change my website?

Never. We only look at your public website from the outside, the same way a visitor would. We do not touch your code, change any settings, or add anything to your site.

What happens after the check?

You get a short list with the most important fix at the top. Send the fix note to your web person or an AI tool, then run the check again to see the improvement measured on your live site.

Start free. Create a free account when you want more checks and saved reports. Choose Pro or Business when you want regular monitoring. Founding Member is a one-time lifetime option if you prefer not to subscribe. See Pricing for what is on sale today.

Fix this first

Your big header photo is slowing the page down on phones

What is happening: The photo at the top of your home page is very large, so phones take about 4 seconds to show it.
Why it matters: Most people leave a page that takes more than 3 seconds to open. You lose visitors before they read a word.
What happens next: Make the photo smaller. Nothing about your design changes.

Illustrative example. Your results depend on your own website.

01How it works

02What you get

See the problem, why it matters, and what to do next.

Try the sample below. Filter by urgency, then open a fix note to see what your web person or AI tool would receive. These are worked examples, not results from a real website.

Fix this first

The header photo is slowing your home page down on phones

What is happening: The large photo at the top of the home page takes about 4 seconds to appear on a typical phone.
Why it matters: Most people give up on a page that takes longer than 3 seconds. They leave before they see what you offer.
What should happen next: Make the photo smaller and serve it in a modern format. The design stays exactly the same.

Important improvement

AI assistants cannot tell what your business does or where it is

What is happening: Your pages do not include the structured details that assistants like ChatGPT use to describe a business.
Why it matters: When someone asks an assistant to recommend a business like yours, you are less likely to be mentioned.
What should happen next: Add your business name, what you do, your area, and contact details in a format machines can read.

Worth improving

Several pages share the same title

What is happening: Six pages all use the title 'Home'. Search engines cannot tell them apart.
Why it matters: People scanning search results see six identical entries and skip past them.
What should happen next: Give each page a short title that says what is on it.

Optional polish

Footer links are a little small to tap

What is happening: Links in the footer are close together and smaller than a fingertip.
Why it matters: Some phone visitors will tap the wrong link. It is minor, but easy to fix.
What should happen next: Add a bit of space around each footer link.
