Have you added a robots.txt and a sitemap.xml, even an RSS file?
While I don't know if this will help with Google, I have my own tiny dumb search indexer, and a sitemap is by far the easiest way for me to index an entire website. I'll discover the sitemap from reading your robots.txt file. RSS helps too, but my indexer uses that mostly to find fresh pages without going through your entire sitemap again. I know Kagi's tiny Teclis indexer also uses RSS files for discovery for their indie web index.
If you're only concerned about Google, then that's probably all you need to / can do. It won't even matter to Google whether or not you put a "Sitemap:" line in your robots.txt if you submitted it directly with them.
As for RSS, Google do regard RSS as another sitemap format. There's info here:
I would not submit an RSS file to Google as your sitemap, stick to XML. But also having RSS can be useful for search indexers, because in one RSS download they can find which pages are new, and can index the actual relevant content of the page without all the ads & other cruft.
An RSS feed is really like a newsletter about your website. So if there's anything where visitors to your website might find value in keeping updated via an email newsletter, consider putting that same "newsletter" content also online, and making that your RSS feed. If the content in your RSS feed contains links to the other pages of your website, that can help with page discovery etc. Something like "we just updated the XYZ product page, check it out!" is zero value, but if you've got an article about "Here's how the brand new ABC feature we just added XYZ Product works", then linking to XYZ Product from within the article & RSS content will make sense. It helps the search engines, but it also helps the user who might want to click through to the product that your article is about.
Thank you. When I add the next updates (maybe that i found one of the objects on my site is on a military firing range!) I should add a news blog and RSS. Thanks
