How to prevent search engines from indexing WordPress search result pages?
You can prevent search engines from indexing your search result pages by making sure they can't access them.
By including the following directives in your robots.txt file, you prevent all search engines from indexing search result pages on your WordPress website, assuming:

- that no search result pages are already indexed.
Here's the code to do this:
If for whatever reason your robots.txt changes, and the search result pages become accessible to search engines it's great if you have a second line of defense. Therefore, we highly recommend that you implement the <meta name="robots" content="noindex"> attribute on your search result pages.
Audit your robots.txt and find out right away!
