Domain Authority (DA) & Page Authority (PA)
Third-party 0–100 scores that estimate ranking strength of a domain or page.
Domain Authority (DA) and Page Authority (PA) are predictive metrics from SEO tools (not Google) that estimate how likely a domain or page is to rank, on a logarithmic 0–100 scale. They are best used comparatively — to weigh prospects against each other or to track a trend — rather than as absolute truth.
