I have a site in a very competitive niche, and SEO for most keywords would involve a huge amount of time and effort.

To research good (low competition, fairly ofter searched) keywords, you need to use some keywords research tool. Then, if keyword is long tail (have at least 2-3 words) and its searched fairly many times a month, you check how big is competition for that phrase in Google. If its low - Tadaaam
