SEO Overhaul, 500 DA40 Backlinks

My technology site already sits at DA 41+, but I want to push far higher in the B2C space. I need a seasoned SEO partner who can take full control of both on-page and off-page work and report measurable gains in rankings, organic traffic, and overall authority.

On-Page Scope
• Run a complete technical, keyword, and performance audit of the entire site.
• Re-write or refine meta titles, descriptions, H1–H3 tags, and image alts so every high-value page is perfectly aligned with target keywords and search intent.
• Optimise internal linking, keyword placement, and density without sacrificing readability or UX.

Off-Page Scope
• Secure 500 clean, white-hat backlinks exclusively from websites with DA 40+—a balanced mix of guest posts, blog submissions, article directories, forum mentions, and profile links.
• Vary anchor text naturally and avoid spam footprints.
• Supply a spreadsheet that lists each live URL, DA, anchor text, and placement date.

Acceptance Criteria
1. Completed audit with prioritised action list.
2. On-page fixes implemented and verified in source code.
3. 500 live backlinks meeting the DA 40+ requirement (no PBNs, no paid link farms).
4. Before-and-after metrics covering keyword positions, organic sessions, and updated DA.

Tools such as Screaming Frog, Ahrefs, SEMrush, Google Search Console, and Analytics are welcome if they help you move faster. Please outline your planned timeline, methodology, and any sample reports so I can see how you work before we begin.
