So what is the process for quickly getting indexed into search engines like Google so that you don’t have to wait weeks for results? Making sure your website or blog has original content is first and foremost. When the search engines index a website, the first thing that they take note of is the content. If you’re not going to have the content on your site original then it will take longer before your site gets indexed. Secondly, don't disregard adding Google Analytics on your website or blog. The free Analytics tool helps you track your traffic and conversions, but at the same time it helps you in letting Google know about your new site. Last but not the least; try to find the top forums or discussion boards in your niche and register with them. Forums have a wonderful rapport with the search engines due to them being updated with new and creative content on frequent occasions. When you register an account on the widely held forums in your niche, you'll have the ability to announce them. However, how does this lend you a hand with your indexing? Forums permit you to attach your website's link in the signature emerges at the bottom of each post. When the search engine spiders visit the forum and scan it for new content, they'll find your link and list it in their index. These are easily the fastest ways to help get your website noticed by the search engines.
You left out Tweeting or pinging it from social networks. Not to mention adding Google Webmaster Tools and updating your sitemap on it. If you tweet something it usually gets picked up by Google in hours and if you submit the sitemap it usually gets indexed within a day. There are exceptions but this is how its looking on my side.
The best way of getting indexed quicker is to get a couple of links form high PR sites. If you have 2 links from sites with PR7 you can get indexed straight away. The lower the page rank the more links you need. Then and there updation is very essential which makes your site to be frequently visited by the spider.
Yes I would certainly agree with the forum and blog commenting in your own niche. This has helped me a lot since last 6 months, which ever site I started I made sure to add them in my forum and blog commenting section and it gave me good results Above all, whenever you do some press releases or submission in networking sites, make sure you ping those links too, it helps a lot!!!!
Pinging your blog is another way of getting index faster another is by submitting them in social networking site and obcourse by creating original content you can get index faster
