Regarding how google would treat such a search... I found a good (?) keyword phrase to the effect of "how to cut paper scissor." In other words, the phrase is grammatically incorrect where most people would search "how to cut paper with scissors." Note the last word is also plural. So, let's say there are a bunch of sites that list: "how to cut paper with scissors" Then I create a page targeting: "how to cut paper scissor" If someone searchs for "how to cut paper scissor," would the existing pages with PR for "how to cut paper with scissors" beat out my phrase even though I'm matching exactly to phrase they typed? I hope my explanation is clear. Maybe it comes down to how google treats plural words and exact phrases.
What it means is that in one factor (out of thousands) you will score better. But that doesn't mean you will rank better as there are 1000 other factors.
Google puts a higher emphasis on exact phrase matches. This, however, does not mean you will automatically outrank the other sites without the exact match as jimkarter has pointed out. Dave
also depends what the user is searching for - exact matches or not. i would totally agree with previous two posts, it will make a very slight difference..
