For years google has been indexing many of my search results pages, which contain links to the articles on my site about essential oils, like this:

example.com/searchResults.php?query=lemon
example.com/searchResults.php?query=lavender
example.com/searchResults.php?query=clove

etc.

The thought recently occurred to me that perhaps I should disallow searchResults.php in my robots.txt file, since all these pages do is show a table of results that link to the various articles. What do the pros say on this forum? Should I continue to let Google do this? Or help direct them to the actual content by filtering out the search results pages?

Thank you!
