i am new in blogging, i want to know why sometimes the total index page decrease? eg. the total index went from 71 to 69. but i keep updating the blog, how come the decrease?
from my experience, first time google indexing your site will index all of the crawled pages and then google will filter the useless page like tag pages and the search pages, leaves only the quality pages of your blog (blog post, sitemap, privacy policy, etc)
