if you what to be shore try analyse all top 30-50 sometimes that give more info then getting analyse top 10. Look if there are no sits there that have lot of BL relevant to your keyword that are not in top 10. I use that meted my self and it save me lot of time I would waste for such keywords. 4 example I hade keyword that look very easy all top 10 was weal now brand whew almost no links average RD/page in top 10 was 6 but on 2 and 3 page i found sits that have 500 RD whew exactly same anchor I want to rank end they was out site top 10
