The titles, especially the head title should be interesting and attractive so users want to click on them when they see them. Also, the head title should contain at least one of the keywords. You should carefully do the keyword analysis before that if you want to appear on the top of the page when those specific keywords are searched. The title should not be too long or too short. Too short titles are not attracting the users to read and make a sloppy impression on them. Also, the long titles could make them think that would be tiring to read the content. The optimal length is nearly 60 characters for a title. Also, don’t forget to use subtitles. There is no certain limit for the number of subtitles you should use but using as many as you can be very effective. These subtitles should also contain the keywords but try not to use them in all of them, it would make the content look complicated. Try to write it as naturally as you can.
