XML Sitemaps: Do You Need One? (Infographic)

Q: Does Google use lastmod, priority and changefreq?

Google ignores priority and changefreq. It uses lastmod if the value is consistently and verifiably accurate, for example when it matches the page's last real modification.

Q: What URLs should go in a sitemap?

Use fully qualified, absolute URLs and list the canonical version of each page you want in search results. Post the sitemap at the site root so it can cover every file on the site. The file must be UTF-8 encoded.

Do you need an XML sitemap? Who benefits, what Google reads and ignores (lastmod, priority, changefreq), the 50,000 URL and 50MB limits, and how to submit one.

Do you need an XML sitemap, and what goes in it?

The short answer: A sitemap lists the URLs you want Google to find. Large, new or media-heavy sites benefit most; a small, well-linked site may not need one. Submitting it is a hint, not a guarantee of crawling.

Based on Google Search Central and Search Console Help.

What it shows

Sitemaps help most on large sites (over about 500 pages), new sites with few external links, and sites with lots of rich media or news content.
A small site of about 500 pages or fewer that's well linked internally may not need one, though most sites benefit.
A single sitemap is limited to 50,000 URLs or 50MB uncompressed.
Google ignores priority and changefreq, and uses lastmod only when it's consistently and verifiably accurate.
Sitemaps must be UTF-8 encoded and use fully qualified, absolute URLs.
Submitting a sitemap is a hint and doesn't guarantee crawling or indexing.

What to do

Building: List only canonical, indexable URLs in full.
Updating: Change lastmod only when the page really changes.
Submitting: Use Search Console and a Sitemap line in robots.txt.

The walkthrough

Do you need an XML sitemap?

You might need one if your site is large, new with few external links, or has a lot of rich media or news content ^[1]. Google says a site may not need one if it's small, about 500 pages or fewer, and comprehensively linked internally, but adds that in most cases a site will benefit from having a sitemap ^[1].

How many URLs can a sitemap hold?

All sitemap formats are limited to 50MB uncompressed or 50,000 URLs per file ^[2]. Larger sites must split their URLs across multiple sitemaps and can list them in a sitemap index file, which can reference up to 50,000 sitemaps ^[2]^[3].

Does Google use lastmod, priority and changefreq?

Google ignores priority and changefreq ^[2]. It uses lastmod if the value is consistently and verifiably accurate, for example when it matches the page's last real modification ^[2].

What URLs should go in a sitemap?

Use fully qualified, absolute URLs ^[2] and list the canonical version of each page you want in search results. Post the sitemap at the site root so it can cover every file on the site ^[2]. The file must be UTF-8 encoded ^[2].

How do you submit a sitemap to Google?

There are three ways: the Sitemaps report in Search Console, a Sitemap line in your robots.txt file pointing to the sitemap URL, or the Search Console API ^[2]. Submitting through the Sitemaps report requires owner permissions on the property ^[4].

Does a sitemap guarantee Google will index your pages?

No. A sitemap helps Google discover URLs, but it doesn't guarantee that every URL will be crawled and indexed ^[1]. Google calls submitting a sitemap merely a hint ^[2].
