Can I code SEMrush?

The dashboard around SEO data — keyword lists, position tracking, a UI — is buildable. The actual product is a continuously updated index of billions of keywords and search results, crawled and refreshed at a scale no solo build gets near.

how this is worked out

Why CanICodeThis says Just pay

  • Tracking your own site's ranking for a specific keyword (via a search API) is a bounded, achievable feature
  • A dashboard showing rank changes over time for a tracked keyword list is ordinary charting
  • For monitoring a handful of your own keywords, a much narrower tool is genuinely sufficient

Read before building

  • Their competitive keyword and backlink database comes from crawling and indexing a meaningful fraction of the web, continuously — not something one build replicates
  • Search-volume estimates require aggregated query data at a scale only a few companies have access to
  • The site-audit crawler that flags technical SEO issues across thousands of pages is real, ongoing crawler engineering

The build spec

Don't rebuild SEMrush's index. Build a narrow rank tracker instead: for a list of keywords you define, periodically query a search API for your site's position and log it over time in a chart. That covers monitoring your own rankings; competitive keyword research at web scale requires an index this site doesn't have and can't reasonably build.
