How Can I Leverage a Competitor's Subsidiary Site

Hi everyone,

I recently acquired the domain of a subsidiary site from one of my biggest competitors in the same niche, where we sell the same products.

Here’s the situation:

• The competitor’s main site still links to the subsidiary site in the footer.
• My competitor's main site has 1M+ monthly visits and 1.5m+ Backlink.
• The subsidiary site has accumulated over 800k backlinks thanks to these connections from the main site.
• Additionally, the subsidiary site has links from:
  • 30+ high-quality domains
  • 30+ domains with average or low value

Given this link profile and traffic, I’m wondering:

• How can I make the most of this site?
• What SEO strategies would you recommend to capitalize on the existing backlink profile and authority?

I would really appreciate the insights and advice from experienced people
