Lovable SEO Checklist: What to Fix Before You Launch

For years the advice was simple: Lovable sites are bad for SEO, because they were single-page React apps that sent crawlers an almost empty page. That changed in 2026. Lovable projects created from May 13, 2026 use server-side rendering, so search engines and AI crawlers receive real HTML. Older projects get pre-rendered snapshots for crawlers and can be upgraded.

So rendering is mostly solved. The reason a Lovable site still gets no traffic is usually the structure the AI generated: missing titles, one generic description on every page, broken headings and no sitemap.

Check which kind of project you have

Open your live page, right-click and choose View page source. If you can read your headings and text in the source, the page is rendered for crawlers. If you mostly see an empty <div id="root"> and script tags, it is an older client-side project. Ask Lovable about upgrading it, or make sure pre-rendering is active.

The 12-point checklist

1. A unique title on every page, under about 60 characters, with the main keyword near the start.
2. A unique meta description per page, under about 160 characters, written to earn the click.
3. Exactly one H1 per page, then H2 and H3 in order. AI builders often use headings for styling.
4. Real links between pages with descriptive anchor text, not buttons that only work with JavaScript.
5. Clean URLs such as /services/web-design, not IDs or hashes.
6. Alt text on every meaningful image, and images compressed to modern formats.
7. A sitemap.xml listing every public page, and a robots.txt that does not block it.
8. Canonical tags that point to your custom domain, not the lovable.app address.
9. Open Graph tags so links look good when shared on LinkedIn, WhatsApp or X.
10. Structured data: Organization or Person, plus FAQ or Product where it fits.
11. A 404 page that returns a real 404 status, not a 200 with "not found" text.
12. Mobile speed: check PageSpeed Insights and fix oversized images and unused scripts.

After launch

• Add the custom domain to Google Search Console and submit the sitemap.
• Use URL Inspection on the home page and key pages to confirm Google sees the content.
• Publish helpful content regularly. A five-page site has very little to rank for.
• Add an llms.txt file that summarises your business for AI assistants.

When moving to WordPress makes more sense

If search traffic is your main channel and a team needs to publish blog posts every week, a content management system is often easier to run than editing an app by prompt. I explain the trade-off in Stay on Lovable or move to WordPress?
