SEO Overhaul for Salvage Car Site

My salvage-car marketplace publishes more than 50,000 fresh listings every week, each tied to a unique VIN. I need an experienced SEO specialist who can push those pages to the top of Google so that when shoppers type a specific VIN, my inventory outranks the competition.

I already tried a mix of on-page tweaks and a handful of directory links, yet rankings remain flat. The two areas that clearly need expert attention are high-quality backlink acquisition and deep technical SEO: crawl-budget management, structured data for VINs, page-speed tuning, and any other code-level fixes that unlock indexability.

Here is what I’m expecting:
• A full technical and content audit identifying every bottleneck that prevents my VIN pages from surfacing.
• A prioritised implementation plan (and hands-on execution where possible) covering site architecture, schema markup, XML sitemaps, internal linking, log-file insights, and core web vitals.
• A sustainable backlink strategy—authoritative, niche-relevant placements only, with clear reporting on targets, outreach, and acquired links.
• Tracking setup and fortnightly reports so we can measure progress in impressions, rankings, and indexed pages for sampled VIN queries.

If you have a track record of lifting large ecommerce or automotive databases, the tools to handle a constantly growing catalogue, and the creativity to build links that stick, I’d like to hear how you would approach this project and what timeline you foresee for noticeable ranking gains.
