SEO APIs.
An SEO API lets software read and act on search performance data programmatically — checking where a page ranks, auditing technical health, generating metadata, or pulling backlink and keyword figures — without anyone opening a dashboard. The alternative is scraping search results yourself and owning that scraper forever.
