Generate an XML sitemap:
To generate an XML sitemap for your Blogger blog, you can use a free online sitemap generator tool, such as XML Sitemap Generator. Simply enter your blog URL and follow the prompts to generate a sitemap file. Once generated, download the sitemap file and save it to your computer.
Upload the sitemap to your blog:
Next, you need to upload the sitemap file to your Blogger blog. To do this, log in to your Blogger dashboard, go to the "Settings" menu, and click on "Search preferences." Under "Crawlers and indexing," click on "Custom robots.txt," and then click on "Edit." In the text box, paste the following code:
User-agent: *
Disallow: /search
Allow: /
Sitemap: [enter the URL of your sitemap here]
Save the changes, and your sitemap should now be visible to search engines.
