Chose a strategy of promoting a new blog on wordpress in a few root volume of pages (3-4pcs.) sealed under highly competitive key phrases, and refer to them in the rest of the low-frequency articles of similar subjects ("long-tail"). The question is whether the presence of these root pages immediately when starting the website? Or at first it is better to fill blozhik "low-frequency" posts, and the most important pages to publish through the year when search engines "make friends" with online?
PS I am a newbie in SEO-promotion, I would be grateful for any advice on the subject.
