Evaluating the credibility of sources is one of the most difficult aspects of a literature review, especially with the ease of finding information on the internet.
The only real way to evaluate is through experience, but there are luckily a few tricks for evaluating information quickly and accurately. Google does not distinguish or judge the quality of results, only how search engine friendly a paper is.
Otherwise, this is usually perceived as being a little lazy, and it is better to organize the review around ideas and individual points.
As a general rule, especially for a longer review, each paragraph should address one point, and present and evaluate all of the available evidence, from all possible differing points of view.
Take solace that even the best scientists can fall into the trap of using poor evidence. If your research program is well constructed, a less-than-perfect literature review will not affect the results.
