Search Console errors

There were huge problems with scanning and indexing on the site.
Google Search Console has only seen one main page.
The programmes made the site on a labyrinth - so that it loaded as quickly as possible and didn't think about SEO at all.
After introducing the lines according to the TZs I have prepared for the programming - Google was able to successfully scan all pages of the site.
Then he began to index them in huge amounts. The website is an online store in Latvia with tens of thousands of goods.
All of the products successfully came to the top edition of Google.
