Include your keywords. Structure your content correctly, make a few title headers in the content that include keywords (use header tags h1, h2, etc.), try to have a keyword density around 2% in your content, and maybe 4% for the whole page including the metatags, alt tags, anchors, etc.
^
Don't listen to the keyword density, that's not accurate. You need to check your competition and you need to add in everything.
Comments, meta, article, wholesite (widgets) etc.
You could have 10+ percent and still be okay it just depends on how.
You could shoot yourself in the foot with this in the long run.
Also you need to know what the LSI is and make sure to get LSI from
competing pages... not wikipedia, amazon etc. Real normal websites
looking to rank for these keywords.
