How many keywords should you focus on per page ?
Title Tags: Make sure to include your primary keyword more organically.
Meta Descriptions: Also, make sure to add your keyword in the text, as well as an attention-grabbing description.
Header Tags (H1, H2, H3, etc.): Put your keyword once in the H1 heading and if possible in the subheading.
Body Content: Use your keyword frequently within the message but do not overdo the keyword.
