will adding my keyword to content article,post etc on my site increase visibility in google? lately my site is dropping traffic bad

??????

U should have your keywords in your posts or your Not targeting them!! Keep the keyword density below 2% and stick it in your H1 tags and LSI keywords in your H2 tags

H1 and H2 tags and also your body, make sure you don't repeat the same word too much

Is that an echo I hear!! Your answer sounds like mine but highly spun lol
