Today we are in a situation where for one search we have millions of answers. How to find out which one is good and which one is mediocre. The search engine attempts to do it based on many factors where the earlier reputation of a blog and site is also one along with the SEO aspects and at that stage the snipping comes in picture because if a write up is perfect in its language and grammar and has been properly snipped by some moderator or editor or even the author while revising, its rank in search engine moves up. So Google also searches under those premises along with its proprietary methodologies but a meticulous snipping would definitely help in ranking.
Knowledge is power.
