Yes, you might. A Google sitemap provides a fundamentally different function from a robots file (or “robots.txt”). Your Google sitemap says what content could crawled, while a robots.txt file says what must not be crawled.
Google is crawling page that are not in my sitemap. Why?
Your sitemap provides hints to Google on what content to include when it crawls your website. It doesn’t stop Google from indexing pages that are not included in your sitemap. Google will continue to explore your website as it navigates your links. A sitemap file does not guarantee that Google will index all the URLs it contains.
How can I stop Google from crawling certain pages?
You can prevent Google and other search engines from crawling specific content by creating a robots file. This file ensures that Google will not crawl or index any content listed within it. If you don’t want something to appear in Google, you must include those URLs in your robots.txt file. You can use Inspyder Sitemap Creator to create a robots.txt file from your list of Excluded URLs.
