Need a SEO roadmap for new website

Hi,

I recently built a completely new website for our tax-related service company, and now I want to focus on SEO to drive organic traffic. I’ve hired someone to handle SEO, but since I only know the basics (on-page and off-page SEO), I want to make sure we’re going in the right direction.

Could you please share a short roadmap or steps to follow from start to finish? For example: • How to structure the process? • How many blogs should we post monthly? • How to handle backlinks? • Anything else to build a strong foundation?

Your insights will help me ensure we’re on the right track. Thank you in advance!
