Direct answer
Begin with a specific search topic and a question you can check. Semrush and Ahrefs both support keyword and competitor research, but their third-party datasets are estimates. Use your own site data alongside them.
The challenge
Beginners often start with a score before defining the goal. A single metric cannot explain search intent or business value. Use tools to form hypotheses and inspect relevant results manually.
What to consider
- Task before tool: separate keyword ideas, competing pages, site checks, and backlinks.
- Data origin: third-party traffic and visibility figures are models; first-party analytics measure something different.
- Learning curve and plan: test the same workflow in both products and check current terms directly.
How to proceed
- Choose one service and list the questions prospective customers ask.
- Research search terms and competing pages; group similar intents.
- Cross-check with your site, Search Console, and editorial review before planning content.
Practical example
A trades business researches searches for its services in its city. Tool suggestions are a starting point; actual service areas and offerings must match the website.

Frequently asked questions
Do I need both Semrush and Ahrefs?
No. Start with one task and check which product presents the needed data clearly. Add a second when you have a specific gap.
Are traffic estimates actual visitor counts?
For other websites these are modeled estimates. Your own analytics and server logs use different measurement methods.
Can an SEO tool guarantee rankings?
No. Tools support research, monitoring, and prioritization; search results depend on many other factors.
