At the bottom of every page in your admin, you will find the SEO Toolkit:
Here, you can add a custom title tag and description. This content is generated automatically for you when you create the page, but you can override that metadata here with your own content.
Title Tag: this will automatically be populated with the "Page Headline" that you add to the top of your page. You will see this title tag appear in two places: (1) this is the name of the page that appears on your browser tab and (2) on search engine results, this will be the name of the page.
See screenshot below.
Description Tag: like the title tag, this content is automatically generated. We will display the first few sentences on this page as your description tag. This content is only visible on search engine results.
You may want to enter a custom description tag here to provide a brief summary of the content on the page, being sure to include any keywords or phrases that someone may search for, especially anything specific to your location.
Here is the page that the above search result points to: http://www.jmitchellassociates.com/about/services
In the SEO Toolkit, you will also see the option to prevent search engines from crawling/indexing the page. You may want to do this if you're building a page that you only want certain clients to access: perhaps you're putting together a page full of helpful resources that you'd like to send to your clients. You would simply create the page, share the URL with your clients once it's approved by compliance, and disable search engine indexing on the page. When disabled, this page will not appear in search engine results — so only people with the link to that page will be able to access it. Voila!
