If you’re creating content online, you know you need more than good writing. Creating SEO content that ranks requires strategy and research. Tools like WriterZen, Semrush, and Ahrefs help you craft content that performs in search engines. Individual contributors or solo content creators often struggle between accessing the best tools and being aware of budget constraints.
But which one is best for SEO-focused content writing? That depends on your context and goals. Here’s an in-depth comparison of these three tools, and how I’ve used each in my online writing process.
Each tool has different tiers, ranging from the most basic plans for individuals to enterprise for agencies or larger businesses. They provide insights into keyword opportunities, content planning, and optimization strategies, often powered by AI writing assistance and SEO content optimization tools. Understanding how each tool enhances your content creation process can help you select the best fit for your specific goals. To do a fair comparison, I looked at the most basic plans of each content writing software.

How Ahrefs Supports SEO Content Writing
Ahrefs is best known for backlink analysis and competitor research, but it also provides powerful keyword and content discovery tools for writers. While it doesn’t have a dedicated writing assistant, it’s excellent for understanding what kind of content wins in competitive niches.
I’ve used Ahrefs before in my own work and then as part of an agency, and it’s honestly one of the best SEO tools out there. Currently, I use the starter plan, which is 27 billed monthly, so I’ll only speak to those features in this section.
The starter plan, though a trimmed down offering of Ahrefs full suite of features, still provides access to a fair amount of great SEO tools. Specifically, I use the site audit feature to keep track of any technical issues on my blogs, as well as the keyword explorer for comprehensive keyword research.
These include:
- Keywords Explorer: Identify profitable long-tail and high-volume terms.
- Traffic & Backlink Data: See which competitor content attracts the most links and visits.
