SEO tools for domain investors

Before you buy or price a domain, check the search demand behind its words. Keyword and backlink tools turn a guess into numbers you can compare.

What to check before you buy a name

  • Search volume: how many people search for the name's keywords each month.
  • CPC (cost per click): what advertisers pay for those keywords. A high CPC means the topic makes money, and end users in that industry pay more for good names.
  • Keyword difficulty: how hard it would be to rank a site on that name's keywords.
  • Backlinks: for expired or aged domains, which sites still link to it and whether the links look natural or spammy.
  • History: what the domain was used for before. Check the Wayback Machine for spam, adult or penalty-prone past use.

Free tools to start with

  • Google Keyword Planner (in Google Ads) gives search volume ranges and CPC.
  • Google Trends shows whether interest in a word is rising or fading.
  • The Wayback Machine (web.archive.org) shows a domain's past websites.
  • Our WHOIS lookup shows who holds a name and when it expires.

Paid tools: Semrush and Ahrefs

Semrush and Ahrefs are the standard tools for this work. They show exact keyword volumes and CPC, keyword difficulty, every backlink pointing at a domain, and the keywords an existing site ranks for. For an investor, that means you can value a keyword .com by its real search demand, or check whether an expired domain's links are worth paying extra for. Full subscriptions are expensive for one person.

Noxtools sells low-cost shared access to tools like these. It's a budget way to try them before deciding whether a full subscription is worth it. Shared access works differently from buying the tool directly, so read Noxtools' own terms before you sign up.

A quick routine for valuing a name

  1. Look up the name's main keyword: note the monthly searches and CPC.
  2. Check comparable sales in record domain sales and NameBio (see our NameBio guide).
  3. For an expired or aged domain, review its backlinks and its Wayback history.
  4. Compare with automated estimates in our domain appraisal tools guide, and see what is my domain worth.
