A tech stack fuels every SEO agency.

So, we’ve compiled a list of the top SEO agency tools by category to help you achieve the best results for your clients.
Keyword Research Tools
Keyword research tools allow you to quickly discover relevant keywords for your clients’ SEO campaigns.
1. Keyword Magic Tool
Semrush’s Keyword Magic Tool will help you identify high-performing keywords for your clients’ websites.
At this point, you might not have a good idea of all the possible keywords your client could rank for. But as long as you have one seed keyword, the tool can generate potentially thousands of related keywords.
First, pick a seed keyword (we’ll use “dry skin” for our example). Select your country and click “Search.”
The results include over 100,000 possible keywords.
On the left-hand side, you have a list of suggested groups. Such as “face,” “cream,” and “itchy.” Clicking on each group will display only the keywords related to that specific topic.
And consider both search volume and search intent to narrow the list according to your goals.
Volume is the number of average monthly searches. While search intent refers to the reason someone searches for a specific query.
Click on a keyword to open it in the Keyword Overview tool for additional insights.
