On-Page SEO Optimization Needed

I need a specialist to refine the on-page SEO of my live website so every URL is fully aligned with current best practices. The focus is strictly on-page work: auditing and improving titles, meta descriptions, headers, image alt text, internal links, URL structure, and any other elements that influence relevance and crawlability.

Deliverables
• Complete on-page audit with a concise findings summary
• Implementation of the recommended changes directly in the CMS (WordPress)
• Brief wrap-up report outlining what was updated and why

You are free to use tools such as Google Search Console, Ahrefs, SEMrush, or your preferred stack—the priority is clean execution and clear reasoning behind each change. My measure of success will be a post-implementation audit showing no critical on-page issues and an upward trend in organic visibility within the following weeks.
