I have started a blog website where i generally write about 1000 words per article. I usually put the exact match keyword once in each paragraph of ~100 words. This then allows me to have a keyword density of ~1% (is that too low?). As I target long-tail keywords, putting the exact match keyword many times in 100 words will look very spammy. I also want to incorporate LSI keywords into my paragraphs. I was hoping to put 1 unique LSI in each paragraph. Thoughts on this? Thanks.
