The SEO page title and meta description are what appears on a search engine when a search is entered. To update your SEO settings, you can do this for each of your pages in your website manager.
The page title is often used as the title in search results. It's recommended to keep it shorter than 60 characters.
Meta description isn't always used in results. Sometimes a search will only show a snippet from the webpage that contains the search term that was typed at the time of the search.
Entering your meta data in these fields helps visitors to click through to your page — especially if it's relevant to the content of your page.
If you already own a domain name then another option would be to ask the people hosting your current domain to 'point' to your new ClubSpark URL (https://clubspark.lta.org.uk/YOURVENUE) so the traffic is automatically re-directed.
