SEO Lighthouse
The AI SEO tool that fixes your site instead of handing you a report
You've seen the SEO reports: forty warnings, half of them jargon, none of them fixed. SEO Lighthouse works on your site itself. It goes through every public page, fixes what search engines and AI assistants read, and tells you plainly what it changed. You publish when you're ready.
- Titles, descriptions and share previews on every page
- Structured data that matches what each page really is
- A sitemap and an llms.txt kept current on every publish
- Speed checked against the measures Google uses
Included from Starter, and an add-on on Essential. Start your site free, no card needed.
Most local websites are hard for Google to read
For the October 2026 Web Index, we measured 295 Ontario trade and clinic websites with Google PageSpeed Insights. Nearly half gave search engines no structured business details at all, and 92% took longer than three seconds to put a headline on a phone.
None of that shows when you look at your own site. But it shows in your rankings, and in whether an AI assistant has anything to say about you when someone asks.
What happens when SEO Lighthouse runs
It finds every real public page on your site: the ones a visitor or a search engine can reach.
Each page gets a title, a description and a share preview, plus structured data that matches what the page is, from a FAQ to a guide to your business itself.
It writes a sitemap of every page, points your robots file at it, and writes an llms.txt that tells AI assistants what your site is about.
For each page it keeps the code for Google's Rich Results test, so you can check the result yourself.
Then it tells you what changed. Nothing goes live until you publish.
Everything search engines and AI assistants read, handled
Pages search engines can read
Every publish pre-renders your pages, so search engines and AI crawlers get your words without running any code.
Titles, descriptions, previews
Each page gets a title, a description and a share preview, so a link to it looks right in Google and in a text message.
Honest structured data
The markup matches what each page really is. It won't tell Google a blog post is something for sale, a mistake that can cost rich results across a whole site.
Ready for AI answers
An llms.txt sums up your site for AI assistants, and the structured data on each page gives them facts they can use.
Speed, measured properly
Performance Lighthouse checks how fast each page shows its content, how much it shifts while loading and how quickly it responds to a tap.
It won't break your site
It doesn't publish, and it doesn't rewrite the code behind your speed scores. You see what changed, then you decide.
Speed, measured the way Google measures it
Performance Lighthouse measures the three numbers Google uses for speed: how long your main content takes to show (LCP), how much the page jumps while it loads (CLS) and how fast it reacts to a tap (INP). It uses a real browser when one is available, and when it can't, it says its evidence comes from your code.
It changes only what the evidence supports, like telling the browser to load your main image first. Everything else comes to you as a clear next step, never as a silent rewrite.
What our own site looks like with it
webcore.pro is a WebCore site, and SEO Lighthouse runs on every publish. On October 4, 2026, our free audit checked the home page, and we ran the same SEO pass over five new pages before publishing them.
94 out of 100

Listed in the sitemap it writes, each with its own structured data, plus an llms.txt for AI assistants.

New pages that passed our own check for FAQ rich results on the first run.
Before you run it
Is this different from an SEO report?
Yes. A report lists problems. SEO Lighthouse fixes the ones it can fix safely on your site, and tells you about the rest in plain words.
Will it change how my site looks?
No. It works on what search engines and AI assistants read: titles, descriptions, structured data, your sitemap and your llms.txt. The one speed change it makes today is telling the browser to load your main image first.
Does it guarantee rankings?
No, and nobody honest can. It makes your site fast, readable and well structured, which is the part anyone can control.
Can I check my site before I sign up?
Yes. Run the free audit on any address. In about a minute you get Google's speed score and what a crawler can read, and nobody asks for your email.
Does it research keywords too?
Your agent researches keywords and competitors when you ask, and keeps what it learns for your pages and articles.
