How to Increase Google Crawling Rate?

One step that can help is if you get new backlinks from quality sites. Also make sure that your titles and meta-descriptions are unique and specific to the page they appear on.

Make sure that you have no technical errors creating more than one URL for the same content. Googlebot crawls with a budget, and if it spends part of that budget downloading duplicate content from different URLs on your site, then it has less budget for crawling the rest of your URLs.

My all meta tags are unique and also content of my all pages are unique.

Are you 100% sure? Does the server handle these url issues without ever creating a second 200 response?

1. incorrect query strings
2. 404 pages (at both the server level and the platform level)
3. https protocol requests
4. different order of the parameters or virtual folders
5. index.html vs. directory root
6. mixed up letter cases
7. double slashes in the file path

If so, you have a rare creation. I have had many sites come to me for help, and almost all of them have at least one of these issues.

The best way to increase crawl rate, besides telling Google that you want it with your Webmaster Tools account and within your sitemap, is to have a very prominent site, well respected in your field and widely linked to. The more important Google sees your site, the better your crawl will be.

Also, make sure your server is handling if-modified-since requests properly, has not the least little DNS problem, no major server delays, no load-balancing issues, makes proper use of E-tags, and uses compression appropriately especially on text files.

If you've got all that handled on your side, then the ball is in Google's court. You cannot force a more frequent spidering, you can only invite it by building a technically solid site with truly world-class content.

You can force more frequent spidering through a variety of black, grey, pink and white hat techniques. There are literally hundreds of ways to get more backlinks to your sites if the purpose of those backlinks is to increase spider activity and not to build PR. The more times you get your pages into Google's pile of pages to be spidered then the more times you will be spidered, mathematically speaking.

yea I am sure my all meta tags and content are unique. I have checked all my content in copyscape.com.

In webmaster tools the radio button of high crawl rate is disable to so no it is not possible.

and Server side my site is OK right now there is no any issue

radio button of high crawl rate is disable

Only more backlinks/PageRank around your site will undo that grayed out choice. Build some buzz, as they say!

There is PR4 of My Home page and all inner pages have PR3. I have already done directories submission, article submission, SBM and i am alway placing comment on my website category related blogs. and Task of Article Submission, directories Submission and SBM is still continue....

One thing that has an effect on how often Google is willing to come (for us at least) is to reduce your page execution to a bare minimum (we shoot for 16ms) and ensure the load you experience from an increase from crawling is handled without an increase in page execution (most often db being the bottleneck).
