SEO Need for website

I am in need of an experienced SEO specialist to improve the current state of my website's SEO, which is currently poor. The focus of this project will be on technical SEO, as I want to prioritize aspects such as website speed, mobile responsiveness, and structured data. In terms of keyword targeting, I am looking to target both short-tail and long-tail keywords. The ideal candidate for this job should have a strong understanding of technical SEO, website optimization, and keyword research. They should also have a proven track record of improving website rankings and driving traffic through organic search.
