Just like me, you must be looking for a free keyword research tool, and you landed on Ahrefs. But little do you know that Ahrefs does not offer free keyword research. After searching for free keyword research tools, I found some and decided to curate a list of Ahrefs alternatives free for SEO and bloggers.
Why choose the Ahrefs keyword explorer alternative?
- Ahrefs is too expensive for keyword research,
- There’s a cheaper alternative to Ahrefs keyword explorer,
- You want a keyword research tool inside the WordPress block editor,
- Free seo tools like Ahrefs offer Site Audit, Content AI, backlink monitoring, and an internal linking solution.
What is the best Ahrefs substitute?
Semrush is the best Ahrefs substitute and the best Ahrefs content explorer alternative, but even Semrush isn’t free.
That’s why I have curated a list of free sites like Ahrefs that provide easy keyword research with little to no limits.
