Have been trying to fix my structured data one after the other which i succeeded fixing till i get to this stage. due have google, tried my best base on tutorials from other site but the more i try the more it develop more issues…

here are the errors

  1. A value for the url field is required.

  2. A value for the author field is required.

pls i need your support here is the url https://www.projectandmaterials.com and secondly i want to ask does your website “structured data” has any relation with its visibility on google search…and what should a blogger consider most in “structured data” settings. thanks
