Sitemap Size effect SEO
-
So I've noticed that the sitemap I use has a capacity of 4500 URLs, but my website is much larger. Is it worth paying for a commercial sitemap that encompasses my entire site?
I also notice that of the 4500 URLs which have been submitted, only 104 are indexed. Is this normal, if not, why is the index rate so low?

Spacecollective, your website's sitemap file(s) don't have any direct impact on search engine rankings. If you have a large website with over 4500 URLs, then most likely you're using content management system (CMS) that "should" be able to create a sitemap file.
If your website's CMS can't do that, then I would recommend crawling the website yourself and updating the sitemap file. However, keep in mind that if you do it manually then you'll need to update it whenever you add or remove a page on the website.
Typically, if your navigational structure is set up in a way that all pages on the website can be crawled via links on the site, you generally shouldn't have anything to worry about.

Sitemaps can go up to 50,000 urls, so 4500 isn't an issue for Google to handle.

Just to add on to Bernadette's post, this section "If your website's CMS can't do that, then I would recommend crawling the website yourself and updating the sitemap file. However, keep in mind that if you do it manually then you'll need to update it whenever you add or remove a page on the website." You can use something like Screaming Frog for this if you were wondering what software to use. It's a very common tool for an SEO to use, so hopefully you'll have it to save purchasing a license to something else.

As Thomas said, 50k is the max but you can also have an index file with multiple sitemaps within it so you can have lots more if needed. A couple of things I would add.
- Manual crawling is fine but remember, that also means that pages that can't be crawled will be excluded from the sitemap which defeats the purpose of the sitemap
- As for why the indexation levels are so low, the first thing I would check is if everything in the sitemap is a 200 response. Make sure there aren't any redirects or 404s otherwise Google may decide not to trust the sitemap.
I hope this helps
