Overall assessment

The site is generally well prepared for AI crawlers, with a working robots.txt, sitemap, and most technical foundations in place. However, the top page is missing structured data, which is the most important issue to address first. There are also a couple of article pages missing meta descriptions, which means AI search tools have less information to summarize those pages. Attending to these areas will help ensure that AI can both find and understand your content more effectively.

Structured data

PAG-06
Result
https://www.davaonline.net/ has no structured data (JSON-LD). There is no machine-readable way to tell AI what the page is about
Diagnosis
Structured data, often added in a format called JSON-LD, is a way to describe your site in a language that AI can easily understand. Without it, AI crawlers visiting your top page have to guess what your site is about, which can lead to missed opportunities for your site to be referenced in AI-generated answers. This is especially important for the top page, as it sets the context for the entire site.
Prescription

Add a small block of structured data to the <head> section of your top page. You can use the following example, replacing the name and URL with your site's details: 

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "WebSite",
  "name": "DavaOnline",
  "url": "https://www.davaonline.net/"
}
</script>

If you use a content management system or a plugin, look for a setting or extension that lets you add this type of structured data. If you have a developer, you can share this example with them. If the file does not appear after adding it, check if your server, hosting service, or CDN is overwriting or blocking changes to your site’s head section.

Next steps
Once structured data is present, AI crawlers will have a clear, machine-readable summary of your site, making it easier for your content to be referenced in AI-generated answers. It is a good idea to run the diagnosis again within a week after making this change to confirm it is being recognized.

Meta descriptions

PAG-02
Result
https://www.davaonline.net/uncategorized/beautiful_landscape/ has no meta description. AI search has fewer clues for summarizing what the page is about https://www.davaonline.net/uncategorized/camp-bernardino/ has no meta description. AI search has fewer clues for summarizing what the page is about
Diagnosis
A meta description is a short summary placed in the <head> section of each page. When it is missing, AI tools have less information to work with when trying to understand or summarize the page, which can make your content less visible in AI-powered search results.
Prescription

Add a meta description to each affected page using the following format:

<meta name="description" content="A summary of this page, around 150 to 160 characters">

Write a brief summary for each page that captures its main topic. If you use a website builder or content management system, look for a field labeled 'meta description' or similar. If you have someone managing your site, let them know which pages need this update.

Next steps
With meta descriptions in place, AI tools will have a clearer idea of what each page is about, making it more likely that your pages will be accurately summarized and referenced. After updating, check the diagnosis again in a week to confirm the descriptions are being detected.

Canonical URLs・Open Graph tags・llms.txt

BriefPAG-04, PAG-05, PAG-08

Some pages are missing a canonical tag (which helps prevent confusion about which version of a page is the main one), and some are missing OG (Open Graph) descriptions, which are used by social media and some AI tools to summarize pages. The llms.txt file is a new, optional standard for signaling AI crawlers, but its absence is not a problem at this stage. Consider adding a canonical tag to the top page and OG descriptions to the pages listed. The llms.txt file can be added if you want to experiment with new AI crawler standards, but it is not required.

Summary

By adding structured data to your top page and meta descriptions to the pages that are missing them, you will make it much easier for AI crawlers to understand and reference your content. Also worth attending to are the missing canonical tag on the top page, the missing OG descriptions on several pages, and the absence of the new llms.txt file (which is optional). After making these changes, it is recommended to run the diagnosis again in about a week to confirm the improvements, and then check in once a month to stay current as AI crawling standards evolve.
