I have a portal which have more than 90 thousand pages and add approx hundred pages daily. And I want indexed all new on Google on daily basis. How to do it.
Indexing all pages of your website on daily basis is only done by google. When google see frequently updation in any website then it automatically crawling it and your site get indexed. You can force google to crawl your website faster by accelerate crawling speed through webmaster tool.
Ping the new pages or use bookmarking sites to get an inbound link. Social media like Facebook will do the same. This is not a guaranty that they are indexed immediately, but it will speed up the indexing process. Are you using a sitemap which is updated automatically when you create new pages?
If its possible ping them or use sitemap for fast index. Well google crawl the website daily. As well use this <META NAME="googlebot" CONTENT="index, follow">
create a sitemap and sign up to google webmaster tool and submit your website there they will automatically index your all pages daily basis
