Sitemaps are an easy way for webmasters to inform search engines about pages on their sites that are available for crawling. In its simplest form, a Sitemap is an XML file that lists URLs for a site along with additional metadata about each URL (when it was last updated, how often it usually changes, and how important it is, relative to other URLs in the site) so that search engines can more intelligently crawl the site. — sitemaps.org

import flask
from flask_sitemapper import Sitemapper
sitemapper = Sitemapper()
app = flask.Flask(__name__)
sitemapper.init_app(app)
@sitemapper.include(lastmod="2022-02-08")
@app.route("/")
def home():
return flask.render_template("home.html")
@sitemapper.include(lastmod="2022-03-19")
@app.route("/about")
def about():
return flask.render_template("about.html")
@app.route("/sitemap.xml")
def sitemap():
return sitemapper.generate()
app.run()With the above code running on localhost, http://localhost/sitemap.xml will serve the following XML sitemap:
<?xml version="1.0" encoding="utf-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>https://localhost/</loc>
<lastmod>2022-02-08</lastmod>
</url>
<url>
<loc>https://localhost/about</loc>
<lastmod>2022-03-19</lastmod>
</url>
