I'm trying to improve the Seo on my website, added most of the texts, texts on images, H1 tags and finally started a blog to improve inside links, add more picture and more key words. I did sitemap and added it to google console. I understand google needs time, but I just received email from google console that there are updates and no page from 'the blog' is indexed - it says 'discovered, not indexed' . Anyone has ideas of what should I do?
