Cron Generator
Build crontab schedules visually instead of recalling the field syntax.
Produce a sitemap.xml so search engines can find every page.
Turns a list of URLs into sitemap-protocol XML, with optional lastmod, changefreq and priority entries.
One URL per line produces a standard `<urlset>`; `changefreq` and `priority` apply to **every entry at once** (there is no per-URL control).
It writes **no `lastmod`**: that field only helps when it is trustworthy, and stamping every entry with the build time is exactly what Google says will make it ignore the whole file (our own sitemap omits it for the same reason, §10.58).
A `loc` must be an **absolute URL** (scheme and host): relative paths and addresses with a `#` fragment do not belong in a sitemap.
One full URL per line
For example `https://example.com/about`; blank lines are skipped, and an empty list is reported.
Pick changefreq and priority
Both are optional hints; leave the defaults if unsure — they do not affect indexing.
Copy the XML
Save it as sitemap.xml in the site root and point to it with one `Sitemap:` line in robots.txt.
Largely no: Google states it does not use them to schedule crawls, so no amount of tuning changes the outcome. What does help is a **trustworthy `lastmod`** plus your internal linking. Do not agonise over those two fields, and do not expect `priority: 1.0` to lift rankings.
The per-file limits are **50,000 URLs / 50MB uncompressed**. Beyond that, split into several files and index them with a `<sitemapindex>` — this tool does not generate the index, so split by directory or language when the list grows.
