What is SEO? 
Search engine optimisation is the process of improving the quality and quantity of website traffic to a website or a web page from search engines. SEO targets unpaid traffic rather than direct traffic or paid traffic

Meta title:
This is the name that shows up for the webpage in the browser tabs.

Meta Description:

The meta description is a snippet of up to about 155 characters – a tag in HTML – which summarises a page's content. Search engines show the meta description in search results mostly when the searched-for phrase is within the description, so optimising the meta description is crucial for on-page SEO.

Click "Save" and now your event page is SEO friendly. 

A meta tag can be found in Mixhubb backend in the basic details section, right next to the branding tab. Here, you can add the event title and description, so that when you share the event link, auto-generated title, description, and images display on the source.
