Hello, I have set-up a Wordpress blog, and the content has quite a niche topic. What I am unclear about is whether I should be targeting the same 4-6 keywords across my entire blog, or do I just target specific keywords per post? Thanks!
You should use different keyword combinations for the different posts. Like keyword for the main site then keyword cheap and other keyword combinations for posts
Certainly you should use different sets of keywords to avoid it look spammy. But, always focus on your niche and your "main" keywords. Overall, my suggestion is do not include unnecessary/unrelated keywords in any of the articles. Focus on the subject and write exactly about it.
Use relevant keyword to the topic! And different on every page (some of them are maybe the same, but you also need different ones)
The main thing is that you must repeat the keywords reasonable times across the blog and the percentage of the keywords in the blog must not be greater than two or three percent. Rest is totally a matter of your choice that whether you use same keywords throughout the blogs or different keywords per post.
