The high stakes of technical SEO

Your website is a critical revenue-generating asset. But what happens when technical issues like indexing errors, botched migrations, or slow rendering start to erode your organic visibility?

You're not just losing rankings; you're bleeding revenue and handing a competitive advantage to your rivals.
Is technical SEO mandatory for you?
You need this if:
  • Your site has 10k+ pages and crawl budget issues
  • You're planning a migration, rebrand, or platform change
  • SERP and LLM crawlers are not indexing your key pages
  • Your dev team needs SEO guidance they can trust
Skip this if:
  • You have a simple 50-page marketing site
  • Your site architecture is already clean
  • All your important pages rank fine
  • You have an in-house technical SEO lead
