Get Indexed Faster

Is it better to submit your website to the search engines or more beneficial to comment on a do-follow blog or website that is crawled often with new content in order to get indexed faster?

You do not need to submit your site to the search engines to get indexed inbound links will achieve this.

Create good content and link build via relevant sites.

Do social bookmarking when you add new content.. your new content will be automatically indexed actually..

Social media and social bookmarking is a great way to get crawled easily IMO.

Create a sitemap and submit it to google.

Search engines automatically finds websites, so there is no need to submit to each search engines.

Social Bookmarking and Social Networking can help your site to get index faster.

It's important to create a sitemap and submit to Google Webmaster Tools. Then just build a few high-quality links and you'll get indexed very quickly. I often have blog posts or other pages indexed in less than 24 hours.

To be get indexed faster is not complex but it requires set of managed activities,there is no any hard and fast rule that how often google or other search engines crawl your website..
but important is to regularly upgrade the content,be active on social media,get quality back links,write quality articles,press releases....
if you are committed,you are supposed to be indexed

But the time of the indexing depens on the google spiders also. I have sites that are indexed every 5 days, and sites that are indexed once at 2 weeks
