I have a longtail that I want to promote. The singular (lets say dog) has 7610 competing pages in "quotes" and 8100 monthly searches according to G's keyword tool. But only has 3 adsense ads on the right hand side. The plural version (dogs) has 2510 competing pages but only 1000 searches. But it has 8 ads on the right hand side. If I target the plural (dogs) will I still rank for the singular (dog) as well? When typed into G with "quotes" the top 10 ranking sites are different for each keyword version. What's yall expert opinion? Thanks!
