#Search engines & link previews

Every page of your site tells search engines and chat apps what it is — without you doing anything. When Google crawls a page, or someone pastes your link into Slack, WhatsApp or X, they get that page's own title, description and preview image, not a generic placeholder.

#What every site gets automatically

• A real title per page — the one you (or the AI) gave the page, not the site's name repeated everywhere. It's also what shows in the browser tab.
• A description per page — the sentence under the title in a search result. If you haven't written one, a sensible description is taken from the page's own text.
• Social previews — pasting a link anywhere shows a proper card: title, description and, if the page has one, a picture.
• A sitemap at your-site.startupjs.ai/sitemap.xml, listing your pages so search engines can find them all.
• A robots.txt that invites search engines in and points them at your sitemap.

Nothing needs turning on, and this works the same on your own domain.

#Writing better titles and descriptions

Titles and descriptions belong to pages, so you change them the way you change everything else — by asking:

Good descriptions are one sentence, specific, and written for a stranger — "Handmade ceramics from a small Lisbon studio, fired weekly" beats "Welcome to our website".

#The SEO panel in your admin

The Routes page of your admin panel has a column called What search engines see: for every page, the exact title and description that get delivered, with a warning chip when something's missing — no title, no description, no social image, or two pages sharing the same title. A banner appears if your site has no home page at all.

At the bottom is a button: Improve my site's SEO. It hands the whole report to the AI Builder as one request — it goes through every page, writes the missing titles and descriptions, and tells you what it changed in the chat. Like any build request, it uses AI credit.

#Good to know

• Changes are live immediately. The moment the AI saves a page, its title, description and preview change with it — no rebuild, no publish step.
• Search engines take their time. Google re-crawls on its own schedule, usually days to weeks; the sitemap helps it find new pages sooner. Nothing you can do here is instant.
• Chat apps cache previews. If you fix a picture and re-paste the link, you may still see the old card for a while — that's Slack/WhatsApp holding a copy, not your site.
• The title, description and preview travel with the page itself, so they work even for tools that never run your site's code — which is exactly the case for most link-preview fetchers.
• Preview images can be an image you uploaded or a link to one; keep it under 5 MB or it's skipped.
