If I want to make my one categary like cats to noindex from google and bing, I add lines in Robots.txt1. Robots.txt File
Edit the robots.txt file, and add lines:
User-agent: *
Disallow: /
(Replace / with the path to the specific articles.)
2. Meta Tags
Use <meta name="robots" content="noindex"> in the <head> section of your HTML for each article you want to hide.
Add a noindex meta tag to the <head> section of the specific pages/posts you don't want to be indexed.
Example:
html
<span><<span>meta</span> <span>name</span>=<span>"robots"</span> <span>content</span>=<span>"noindex, nofollow"</span>></span>
Use a robots.txt file to disallow search engines or add a <meta name="robots" content="noindex"> tag to the articles. This should prevent indexing by Google and Bing.
