According to some articles that talk about crawl budget, we should decrease the number pages crawled and provide the only important and valuable pages to search engine crawlers.
We have 3,000 articles on our web site but the number of indexed pages in Google Search Console is 12,000. The difference between 12,000 and 3,000 is our tag pages and author pages.
What should I do with tags and authors page? Should I block these pages? If so, where would the block be implemented? In robots.txt or meta tag in headers?
