Keyword difficulty is an SEO metric that estimates how hard it will be to rank on page one for a search term. Most SEO tools score it on a scale such as 0 to 100, where higher numbers usually mean stronger competition from authoritative sites, better backlinks, and more established pages already ranking.
What keyword difficulty actually measures
Keyword difficulty is not a Google metric. It is a tool-generated estimate based on signals such as the backlink strength of top-ranking pages, the authority of ranking domains, and sometimes the search intent consistency of the results. A keyword with a difficulty score of 18 often has weaker competition and fewer strong referring domains in the top results. A keyword with a score of 72 usually means you are competing against large sites with deep link profiles and mature content.
For marketers, the useful question is not “Is this keyword hard?” but “Can our site realistically outrank the current results with the content, links, and distribution we can execute in the next 60 to 90 days?”
Why keyword difficulty matters for growth
Keyword difficulty helps you prioritize terms that can produce traffic and conversions without wasting months on unrealistic targets. If your site is new or has limited authority, going after broad, high-difficulty keywords can drain budget and content resources. A smarter workflow is to balance three inputs: keyword difficulty, search volume, and business value.
At TLSubmit, this usually means building clusters around lower-difficulty, high-intent terms first. These pages are faster to rank, easier to support with internal links, and more likely to generate pipeline if they match a clear use case, comparison, or buying stage.
A practical prioritization rule
Score each keyword on four factors: difficulty, intent, revenue relevance, and content effort. A keyword with moderate volume, low difficulty, and strong purchase intent will often outperform a high-volume vanity term that is nearly impossible to rank for.
How to use keyword difficulty in a real workflow
Start with a seed topic, expand it in your SEO tool, then sort by difficulty and intent. Remove terms that do not match your offer. Group the remaining keywords into clusters and assign one primary keyword per page. Next, review the top 10 results manually. Check content type, depth, backlink profiles, and whether the ranking pages are product pages, blog posts, or category pages. This tells you what Google expects.
Example: if you sell email outreach software, “email marketing” may have very high difficulty and mixed intent. “Cold email subject line examples for SaaS” may have lower difficulty and clearer relevance. Instead of chasing the broad term, publish a targeted page, support it with internal links from related articles, distribute it through newsletters and social posts, and use outreach to earn a few relevant backlinks. That is a realistic path to rankings and qualified traffic.
