You can use 3rd party indexing services, which starts from $17 per month.

It's depends upon your SEO strategy. Search engines give much weight to the H1 Tag. I vote for your second option : Site Name + Some Important Keyword.

Hi Dirk,

thanks for the most valuable reply. But, it is better to have some new page / backlink submission system.

And also AHref, raven tool's backlinks are not useful in my view. Why because, If we have good number of backlinks in moz, then our DA & Trust will increase.

I have some good number number of backlinks in my webmaster tools. But, open site explorer is showing very few backlinks. How to force moz to crawl all the backlinks? Or is there any way to submit backlinks to moz?
