Google asserts that this feature gets automatically enabled only when it is sure that user will click on first result. Although it is humble enough to accept that they cannot be 100% correct at all times. This means next time you look-up something over google using a firefox or mozilla, your browser is likely to end up caching webpages you haven't even visited. Found cookies of some unvisited websites recently? Well you have been prefetched!!

If you have been paying attention to this, then you now know that maybe you should be targeting those niche areas. I say niche, because if you look at content of messages you will see that they are very specific. Some of education messages I get are for particular schools, or programs – like website development, search engine optimization, business management, small business development or entrepreneurship. Same with career e-mails I get, they are always targeted at a specific profession – nursing, truck drivers or other medical related fields.

So how can this help you? Supposed you are getting 100 messages per week about careers. You go through these and group them by profession. Once you have done this you notice that 75% of messages are about nursing. You now have a profession you can target for additional research.

You first start performing some preliminary research to see if this niche is worth targeting.

If your research shows that it is worth pursuing, then look at what types of phrases are being used and who is in top 10, 20 or 30 sites providing this type of information. Look at pure search engine listings, but also pay attention to paid advertising – since this will give you a good idea if you will make money by targeting this niche.

Once you have done your homework, and find that this is indeed a field worth pursuing then it is time to start developing your website, and thinking about type of content you will be offering to your site visitors. You may want to think about offering free courses on nursing, what it is, how someone can become a nurse – basically what you would want to know before you decided to pursue this as a career.

It is very easy building your business, if you spend a little time and look at unconventional ways of determining what business you need to get into – that is, what niche you should be targeting.

A little research and your spam e-mail box could help you make a name for yourself in world of internet marketing.
