One of the most important factor to determine whether a website is success or not if to get a lot traffic to your site, other than that, you also need to get your website indexing to Google as soon as possible.
I have done some research and found out the this method is one of the easy way out. Each time your have a new site and want to get it index in the shortest timeframe, you can try out the below method:
Remember to replace the abc.com or abc to your domain that you want to index. eg, abc to your domain name.
Cut and paste the 1 to 20 one by one into any internet explorer URL bar, repeat them until you have completed all.
I have tested this and you can see this in less than 10min based on my testing result.
Happy testing. 🙂
