What is the best way to get credible content on the internet?

This is my first post.

I am Saurav, a freelance research guy for last 3 months. I am in to ML, NLP, Opinion mining, sentiment analysis etc.

My question is about getting credible content from internet on any subject.

Example:-

1. I was researching about buying a mobile phone( Nokia X)  on web. I spend almost half a day researching about it. I found exactly opposite reviews about the phone. Some reviewed it very good, some said it is average and some said it is worst. I got really confused, finally called some friends to take there opinion and took a decision after that. If I wouldn’t have researched,I wouldn’t have face the dilemma. 

2. I was interested in learning about social media marketing and looking forward for a credible source. Again I faced a similar dilemma.There are loads of information but no way to learn which is good.I got exactly opposite review about same information.

Can anyone in the group suggest a clear path to get credible information about any topic.Is there any general rule which i can follow?

Does anyone know any startup who is working hard to simplify this process of getting credible things over internet easy so that decision making process can be simple and fast?
