Impact on SEO of hiding page title using Page Options

[viktorrenkema]

Once we release Page Options, users are able to hide the title and/or description of a page. Writers may wonder if this has any impact on SEO, as titles (headings like h1, h2, h3) impact SEO.

We want to clarify to users what the impact is on SEO, which is:

• if users added a title, and then hide it using Page Options, the title will still be there in the HTML page title and added to SEO metatags.
• if users never added a title, it will logically also not be there in the HTML/meta tags as there is nothing to add.
• technically the <h1/> not being in the DOM when hidden using Page Options will impact SEO, but we expect the impact to be very very low since it'll be in the space header.
