Rank tracking and link data from Moz Pro
Moz has been measuring domain authority since the metric was invented, and its rank tracking, link explorer and keyword research still cover what a content site needs to watch. Its free browser extension is what most people meet first. The index is smaller than Ahrefs', and the entry plan is priced for one site rather than for an agency.
Our note
The entry price is the argument, at $49 a month for a single site against what Ahrefs and Semrush charge. The link index behind it is smaller. Buy it for rank tracking and check backlinks somewhere else.
Keyword and competitor research at agency depth
Semrush is the tool an SEO reaches for when they need to know what a competitor ranks for and what it is worth. Position tracking, site audits and keyword gaps are all there, along with newer reporting on how brands surface in AI answers. It costs more than most creators can justify, and the entry plan tracks five sites and 500 keywords.
