How to choose between Ahrefs vs. Semrush

Now that you’ve viewed our Ahrefs and Semrush comparison, you can start thinking about which is right for you. When choosing a paid SEO tool, there are a few considerations — especially if you’re selecting a tool for your team vs. yourself, considering Moz alternatives like Ahrefs or Semrush could be beneficial.

Here are our tips for choosing between Ahrefs vs. Semrush:

1. Outline your requirements
2. Build your score sheet
3. Test your options
4. Choose your SEO tool

1. Outline your requirements

Start by outlining your requirements, like the following:

• Budget
• Capabilities, like keyword research and SEO audits
• Access, like if multiple users will use the same account or one account per user

Reference your requirements against Semrush’s and Ahrefs’ pricing plans. Depending on your budget and required capabilities, one tool might be the only option. For example, if you want a tool that can assist with content, you’ll likely lean towards Semrush since Ahrefs doesn’t have a content toolkit.

2. Build your score sheet

Next, create a score sheet based on your needed capabilities, like keyword research.

The purpose of this sheet is to provide you and your team a place to store your thoughts on each tool’s features, like keyword research or SEO audits. This sheet can also keep you accountable for explaining why you liked or disliked a feature vs. saying you “just didn’t like it.”

3. Test your options

Finally, you can start testing your options.

With Semrush, you’ll have access to a free seven-day trial. In comparison, Ahrefs provides a freemium version of its software for verified site owners. You’ll need to review each tool’s pricing plans to determine the package you need to evaluate.

You may need to sign up for a paid plan depending on your needs.

If you’re disappointed with both, consider Moz Pro — and explore its pros and cons in our breakdown of Moz Pro vs. Ahrefs or in our breakdown of Moz vs. Semrush.
