WA Progression - some slight issues

Hi all

I hope everyone is staying safe and are well?

Just a quick update on my progression at WA.

I did create a website at the beginning of my membership here but I soon realised that the niche was rushed and was not for me. So I decided to try the affiliate bootcamp which is going well, I have had 3 people join but only as free members at present and my site is coming along nicely. I have noticed that a lot of my posts were indexed by Google on my last website and it happened quite quickly, however this time although my site has been indexed, my posts don't seem to be as quickly as before. But I am wiling to take the rough with the smooth.

I did notice that my last sites health was very good however my new site says it needs improvement. Can anyone help by informing me how I can rectify the below
