I have this week undertaken to engage in learning all about keywords. I've tried in the past but keep hitting a stumbling block. In all the tutorials I have watched/read, they say I should look for keywords that the most people are looking for. Use keywords that people who search are using, they all say. Leaving aside the commercial aspect to the value of keywords I found this to be quite easy, especially using software like Market Samuai, but today, after all the efforts to persuade me to look for the words that are most searched for, I received another tutorial saying I should look for the keywords that are least used, because there is more chance of being found for those words. This is the bit I can't, and have never been able to get my head around and I wondered if someone could explain it. Do I use popular keywords that the majority of searchers use, or do I use the keywords that are least used by other webmasters? The bit that really confuses me is that the tutorials in one breath say 'use the most popular' and in the other breath say don't use the most popular in order to conquer the niche. So which is it. If I use the most popular keywords, am I losing out and making it harder for myself, and if I use the least used keywords, am i not damping down my chances of attracting high volumes of traffic? Thanks.
