Key words. SEO
The effect is the same.
But for the whole site in general, better pick up at least 20 - 50 key words and phrases in advance (and sundry, and then it's not the limit), they will need when writing a first post and anchor text for inbound links.
The pages and posts (articles), I advise you to use no more than three key dependent, but rather continue from each other.
Example in my head:
- To promote a site.
- How to promote a site.
- To promote a site in search engines.
Now it's small - to prescribe (to mention) the data phrases in the text, will be five times more than enough.
