Increase quality back links to your domain. Create a blog for your website and update it daily. Daily blog update will help your website/domain to be regularly crawled by Google, which will be helpful in fast indexing of pages of your website.
Add new pages to your site daily with fresh content. Google likes original content and will sens its spiders to crawl your site.
Frequent update in conent increases the crawling frequency. But it doesn't mean you will get good ranking. For ranking you should have build some quality backlink.
I agree with diyakapoor. By adding a blog to your website and updating it frequently will definitely help you get more pages indexed.
If you have a site and not a blog, then update your h1 tags smartly. Create atleast one new page every week or alternate days and keep a constant watch on the time it takes to get indexed in google. In this way if for example your new page takes 24-48 hours to get indexed, then accordingly implement a plan to create new pages to your site at regular intervals.
Create link to your internal page. Submit sitemap in google webmaster tool. Submit RSS feed to RSS feed directories. Update your website/blog with quality and fresh content. Bookmark your website/blog on quality bookmarking sites. Promote your website/Blog on social networking site and microblogging site like facebook and twitter.
Submit xml sitemap in Google, proper intenal linking, do social bookmarking, create blog and update blog regularly are helps to increase index pages.
To get your pages indexed by google you only need to write unique content and submit your sitemap using google webmaster tools. You do not need links, social bookmarking or anything like that.
That all helps but you do need links, social bookmarking and other things to promote those links. have no promotion is like have a shop in an area where you get no customers or traffic and that wouldnt make any sense
in case you'll be adding new pages to your site, make sure to submit the new pages to top social bookmarking sites, and get some links from other sites also for faster indexing, that way you'll see a difference with the number of indexed pages sooner or later
Have unique content on ur website and add as much pages as u can add and ur website will get more indexed pages!
Generate a sitemap of your site and submit it to webmaster tools. Make sure that the file type you are submitting is an xml type.
I added a blog to my website and also update frequently, but it seems that only my blog pages get indexed. What is the problems?
