Semrush and Moz both cover keyword research, backlink analysis, and site auditing — the core SEO toolkit. But Semrush has significantly expanded its feature set in recent years, adding PPC data, AI content writing, and local SEO tools. Moz remains a strong choice for teams who want a focused, trustworthy SEO platform without the complexity of Semrush's full feature list.

Honest assessment
Semrush is the more powerful platform by almost every measure — more keywords, more backlink data, more features, and more integrations. Moz wins for teams that value simplicity, the trusted Domain Authority metric, and slightly more approachable pricing at the entry level. If you outgrow Moz's feature set, Semrush is the natural upgrade. Moz is still a solid choice for SEO fundamentals — it is just no longer the most feature-rich option in the market.
Both Semrush and Moz are research platforms — they provide the data you need to make SEO decisions, but they do not automate the content creation and publishing that turns that data into rankings. Fonzy bridges this gap: it uses keyword research to automatically generate and publish hundreds of SEO-optimised pages, complete with schema markup and internal linking. If you want research to translate into published pages without a content team, Fonzy is the automation layer that Semrush and Moz are missing.
The smarter alternative
While Semrush and Moz both require significant manual effort, Fonzy automates the full SEO pipeline — from keyword research to published pages.
