I know that Google don’t guarantee for indexing every single web page, but I need some clarification about that, because most of the SEO masters are saying
“Submitting Sitemap in GWT is the most important task for indexing a page”.
I had submitted my website’s site map before several months (may be years).
My sitemap contains 2253 web pages, out of that only 64 pages has been indexed so for. These 64 pages were indexed few months before itself which means, after those 64 pages Google hasn’t indexed even a single page.
What would be the reason?
