How to correct Google meta data info

Hi I’ve just got my website up and running and I’m hitting around 200 views a day but the problem Im having is when searching for my website in google it comes up the name of the site but the info below is very scattered about posts, also how do I add the correct meta data for say if someone typed in House music blog, my site would come back in the search results somewhere at least? many thanks i know this is pretty basic stuff but theres alot of confusing info out there, thanks again andy. PS my site is https://www.knightsoftheturntable.co.uk
