Do I need to know code to do SEO myself ?

[Sankara Vignesh]

Need to know about the coding knowledge for doing the seo process within the website design and development...?

No. You need to learn only few HTML codes for h1, alt, title and meta tags which are essential in SEO.

once you get some fluency my best resource is [w3schools.com...] for a quick reference.
