Since all features are implemented within the Horizons tool, you will need to prompt the application directly to request SEO settings. The tool will then guide you through any necessary steps on your end.
Hostinger Horizons is now automatically generating sitemap and robots.txt for customer websites after publishing the web application, to make websites more SEO friendly (only for projects with a custom domain).
Also, Horizons generated code follows the best practices for website structure, so web crawlers, such as Google, could easily identify the content and rank the project.
Note that it's better to avoid requesting more than 5 actions inside a message if you prefer to write in the chatbox of Horizons. Also, be aware that the Horizons tool-generated results work better when prompted using AI-generated text (like Gemini or ChatGPT).
When it comes to setting up some SEO features inside your Horizons project:
Regarding updating meta title and meta descriptions, such a prompt works: update meta title 'my web app'
Regarding a WWW prefix: you can add it to your web application by going to your domain's DNS settings and adding the following CNAME record to it:
Type: CNAME
Name: www
Point to: yourdomain.com (insert your domain without https:// or www)
TTL: 300
You can check the final result in the example below:
After you do this, all is done, and you only have to wait! Have in mind that such DNS changes might take around 24 hours to fully propagate in all servers and be visible in all devices.
Regarding your web application indexing and display inside search engines, please follow the steps here.
