Create an XML Sitemap From a List of URLs

To create an XML sitemap, paste your page URLs one per line into the ByteTools XML Sitemap Generator, set the last-modified date, change frequency and priority, and it produces a valid sitemap.xml you can copy or download instantly. It validates each URL and runs entirely in your browser — no crawling, no uploads.

A sitemap is a simple XML file listing the URLs you want search engines to know about. It won't magically boost rankings, but it helps crawlers discover your pages efficiently — especially useful for new sites, pages with few internal links, and small static projects where a heavyweight CMS plugin would be overkill.

Why a sitemap helps and who it's for

Search engines find pages by following links, but that process is imperfect — deep pages, freshly published content, and thinly linked URLs can be missed or crawled slowly. A sitemap hands crawlers an explicit inventory of your URLs so nothing important gets overlooked. This tool is built for small static sites, landing-page collections, documentation, and quick fixes where you just need a clean file fast without installing anything.

How to generate a sitemap in your browser

1. Paste your page URLs into the input, one per line.
2. Pick a lastmod date (it defaults to today), plus a change frequency and priority.
3. Fix any invalid URLs the tool flags — it checks each line is an absolute http(s) URL.
4. Copy the XML or download sitemap.xml.
5. Upload it to your site root and reference it from robots.txt or submit it in Search Console.

Which sitemap fields actually matter?

The sitemap format supports four tags per URL, but they don't all carry equal weight with Google. Here's what to focus on.

Field	Does Google use it?	Advice
loc (URL)	Yes	Required; must be absolute and canonical
lastmod	Yes, when accurate	Set to the real change date, not always today
changefreq	No	Ignored by Google; other engines may read it
priority	No	Ignored by Google; don't spend time tuning it

The practical takeaway: get your URLs and honest lastmod dates right, and don't agonise over changefreq and priority.

Frequently asked questions

Do changefreq and priority really affect Google?

No. Google has said it ignores both and relies on lastmod (when accurate) plus its own crawl scheduling. Other search engines may still read them, so they're included for completeness — but they're not worth fine-tuning.

How many URLs can one sitemap hold?

Up to 50,000 URLs and 50 MB uncompressed per file. Beyond that you split into multiple sitemaps and list them in a sitemap index file. For most small sites, a single file generated here is more than enough.

Does a sitemap guarantee indexing?

No. A sitemap aids discovery by telling crawlers your URLs exist, but indexing still depends on page quality, internal linking and crawl budget. Treat it as an invitation, not a command.

Where do I submit my sitemap?

Upload it to your site — commonly /sitemap.xml — then submit the URL in Google Search Console under Sitemaps and in Bing Webmaster Tools. Adding a Sitemap: line to robots.txt lets any crawler discover it automatically too.

Should lastmod be the genuine modification date?

Yes. Google uses lastmod as a crawl hint only when it's consistently accurate. Sites that stamp every URL with today's date teach Google to ignore the field, so set it to when the content actually changed.
