I am glad to have BiQ :)
I already have Frase and MarketMuse for content optimization, now I have BiQ, I just use Content Intelligence and cooperate with MarketMuse to insert some keywords to my blog, BiQ also shows some session of articles need to be improved, then I would rewrite and insert some keywords in the articles, then I can see MM for this process will improve my score of SEO, I am happy :)
