Hi @anpanman
There are many issues that might prevent your blogs from being indexed by Google. And I find this blog post from Ahrefs quite insightful on this matter. They cover the common issues that your blogs don’t get indexed and provide you clear solutions like:
- Crawl blocks in your robots.txt file
- The sitemap you submitted may not include all your blogs (indexable pages not in your sitemap)
- Rogue canonical tags
- Your blog content is yet to be valued enough
I hope that this helps!
