To index your landing page and make it visible to search engines:
First of all, consider indexing it by ticking the box “Page indexed by search engines” in your editor:
This step is essential for allowing bots to access it, but this doesn’t index the page automatically.
There are then two ways to index the page:
2.a. By placing the URL somewhere online (for example, on your website, in a CTA or in a text). This is what will allow bots to create a path to this URL.
NB. Sharing the URL in a post on social networks or in an email campaign is not enough because, by default, these URLs are configured with a “no follow” tag which prevents search engines from accessing them.
2.b. To index a landing page manually without waiting for the URL to be published online, don’t hesitate to request this on the Google Search Console, by following these instructions.
Tips and Tricks
To see if your landing page has been indexed by Google, search site: followed by the page’s URL.
