By default, all publications are optimized for search engines. As soon as a publication is marked Online it is also available for search engines to index and show in their search results. When the SEO option in Publitas is disabled, your publication will not be indexed by search engines and therefor not end up in search engines.
To disable SEO, click on the three dots next to the group name and select Viewer Customization. Under the Advanced settings tab you'll find the option to disable the SEO for all publications in the selected group.
Please note: Publications that have already been indexed by Google, before SEO was disabled, will remain available via Google.
If you need SEO disabled for a single publication or a selection of publications only, please contact firstname.lastname@example.org and we'll have a look at the options available for you.
