Before your brand can be recommended, it needs to be found.
If search engines, AI tools and other crawlers struggle to access, render or understand your website, your visibility is limited before your content has a chance to work.
This guide covers four practical areas to check:
- JavaScript
- Chrome Lighthouse and agent readiness
- Server logs and crawler access
- Schema and crawler control
The aim is to remove the technical barriers that stop your brand from being found, understood and trusted. And, ultimately, chosen.
Check what JavaScript is hiding.
JavaScript helps make websites interactive, but it can also make important content harder for crawlers to read.
Some search engines and AI tools can process JavaScript. But you should not rely on every crawler seeing your website in the same way a person does.
For an easy, quick way of understanding how much content might not be seen by traditional search an AI, use our comparison tool below. It compares your page’s raw HTML against the fully rendered version to show you much content is invisible to crawlers that can’t render JavaScript.
While some search engines and AI tools can process JavaScript, you should not rely on every crawler seeing your website in the same way a person does. If key content is missing from the raw HTML, it may only be loaded after JavaScript runs, which creates a potential barrier for search engines and AI crawlers.
That can be a problem if your most useful content is hidden behind scripts, tabs, filters, animations or dynamically loaded sections.
Focus on three things:
01. Key content:
Make sure your main headings, service copy, product details and FAQs are available in the HTML, not only loaded later by JavaScript.
02.Internal links:
Check that important links can be found in the source code. If your navigation or related links rely too heavily on JavaScript, crawlers may miss useful pages.
03. Blocked scripts:
Check that your robots.txt file is not blocking important JavaScript or CSS files. Crawlers often need these files to understand how the page works.
JavaScript is not bad for SEO or AI visibility. However, if a crawler cannot see it, it cannot understand it. And if it cannot understand it, it is much less likely to use it.
Get agent-ready with PageSpeed Insights.
How to use PageSpeed Insights for Agent Readiness
- Head directly to the official Google PageSpeed Insights platform.
- Enter your website’s URL into the search bar and click Analyse.
- Once the analysis completes, scroll to the Lighthouse score dials.
- Look for the Agentic Browsing dial to review your pass/fail breakdown across WebMCP, semantic accessibility, and your llms.txt
Look for three key things in your score:
01. Clear code labels (accessibility):
- What it means: AI bots do not look at your website’s design. They only read the background code.
- What to fix: Make sure every button, image, and form has a clear text label in the code so the bot knows what it does.
02. A steady page (layout shift / CLS):
- What it means: The elements on your page should not jump around while loading.
- What to fix: If a button moves while an AI bot is trying to click it, the bot will click the wrong thing and break. Give your images fixed sizes so the layout stays still.
03. An AI welcome file (llms.txt):
- What it means: A simple text file at ://yourdomain.com that explains what your website is about.
- What to fix: Create this basic text file so agents clearly understand your website.
- Note: There’s a lot of discussion and controversy about llms.txt at the time of writing. The context in which we recommend it here is for agentic use, not search.
Check your server logs.
Server logs show which bots and crawlers are visiting your website.
Google Analytics will not always show this clearly, so you may need access through your hosting provider, developer, CDN or tools like Cloudflare.
Ask for a recent server log export (stick to requesting a week, server logs can be huge), then search it for AI and search crawler names like:
- GPTBot
- ChatGPT-User
- OAI-SearchBot
- ClaudeBot
- Claude-SearchBot
- PerplexityBot
- Googlebot
- Bingbot
You are looking for three things:
01. Are they visiting your website?
If AI crawlers are not appearing at all, it may mean they cannot access your site or are being blocked.
02. Which pages are they visiting?
Check whether they are reaching your important pages, such as service pages, product pages, guides, case studies and blog content.
03. Are they getting errors?
Look for repeated 403, 404 or 500 errors. These can suggest that crawlers are being blocked, sent to broken pages or hitting technical issues.
A healthy pattern usually means crawlers can access your key pages without lots of errors.
A problem pattern might mean they are missing important content or wasting time on low-value pages. Or, it could been they are being blocked before they can even understand your site.
If you are not sure what the logs are showing, this is where a technical SEO review can help.
Check schema and crawler control.
Schema and robots.txt help crawlers understand what your website is, what your pages are about and which areas they can access.
They do different jobs, but both matter.
Schema gives search engines and AI systems extra context about your content. It can help them understand your business, services, products, reviews, FAQs, articles and key information.
Robots.txt controls which crawlers are allowed to access parts of your website.
Start with three checks:
01. Check your schema:
Use a schema testing tool to see whether your important pages have structured data in place.
Focus on pages like your homepage, service pages, product pages, articles, FAQs and case studies.
You are looking for clear, relevant schema that matches the page. For example, organisation schema, local business schema, product schema, article schema or FAQ schema.
02. Check your robots.txt file:
You can usually find this by adding /robots.txt to the end of your domain.
For example:
yourdomain.com/robots.txt
Check that you are not blocking important pages, folders, JavaScript files or CSS files that crawlers need to understand your site.
03. Decide how you want AI crawlers treated:
Some websites choose to allow AI crawlers. Some choose to block them. The main thing is to make that decision properly, rather than leaving it to chance.
Review whether your robots.txt file is blocking or allowing the crawlers you care about.
Schema helps machines understand your content.
Robots.txt helps control access to it.
Together, they give your website a cleaner, clearer foundation for search and AI visibility.
Not sure what your site is showing to AI?
These checks are a good starting point. They help you understand whether your website can be found, accessed and understood by search engines, AI tools and other crawlers.
But they are also only the first layer; if your logs are hard to read, your JavaScript is hiding key content, your schema is missing, or your robots.txt file is blocking the wrong things, it can quickly become technical.
That is where we can help.
Bamboo Nine’s AI Visibility Review looks at how accessible your website is, how well your content can be understood and what needs fixing first.
