Each of these tools has distinct features that cater to different aspects of keyword research and SEO planning. By the end of this guide, you’ll have a clearer understanding of which tool or combination of tools will best suit your specific SEO needs.


SEMrush stands out as a comprehensive SEO tool offering extensive keyword research capabilities. It provides detailed insights into keyword trends, search volumes, keyword difficulty, and SERP features. One of its standout features is the Keyword Magic Tool, which offers an expansive database of keywords along with variations and related search terms. SEMrush also excels in competitive analysis, allowing users to explore competitors’ keyword strategies, which can be instrumental in crafting your own SEO plan.

Beyond keyword research, SEMrush offers a suite of tools for site audits, tracking rankings, backlink analysis, and content optimization. Its ability to provide a holistic view of your SEO and marketing efforts makes it a preferred choice for many professionals. However, its extensive features come at a premium price, making it more suitable for larger businesses or agencies rather than individual bloggers or small startups.


Ahrefs is renowned for its powerful backlink analysis capabilities and also shines in the realm of keyword research. It offers an extensive database for keyword research, including search volume, keyword difficulty, and click metrics. A unique feature of Ahrefs is its ‘Clicks’ data, which shows the search volume and actual clicks, providing insights into user behavior.

Its Keywords Explorer tool offers detailed analysis not only for Google but also for other search engines like YouTube, Amazon, and Bing. Ahrefs also provides valuable insights into competitor keyword strategies and SERP analysis. While Ahrefs is a robust tool for SEO professionals, its pricing is on the higher end, and its interface might be slightly overwhelming for beginners. It’s ideal for medium to large-sized businesses and agencies looking for an all-in-one SEO toolkit.

Moz Keyword Explorer

Moz Keyword Explorer is known for its user-friendly interface and accurate keyword data. It offers valuable insights into keyword search volume, difficulty, organic CTR, and priority (a combination of all metrics). One of Moz’s unique features is its ‘Priority’ score, which helps to identify the most valuable keywords to target based on a combination of factors.

Moz also provides SERP analysis and suggests related keywords and questions, enhancing content strategy development. While it may not have as extensive a database as SEMrush or Ahrefs, Moz is known for its accuracy and ease of use, making it suitable for beginners and small to medium-sized businesses. It also integrates well with other Moz tools for a comprehensive SEO strategy but may require an upgrade to access its full range of features.


Glimpse is a newer player in the keyword research tool market, offering unique insights by leveraging trending data from various sources, including Google Trends. It’s designed to identify emerging trends and popular topics, which can be invaluable for content creation and SEO strategy. Glimpse is particularly useful for identifying niche markets and capitalizing on upcoming trends.

While Glimpse may not provide in-depth keyword analysis like traditional tools, its focus on current and emerging trends makes it a valuable addition to any marketer’s toolkit. It’s particularly suited for content creators, marketers, and businesses looking to stay ahead of the curve with fresh and trending topics. However, one might need to supplement Glimpse with other keyword research tools for detailed keyword difficulty scores and comprehensive competitor analysis.

Google Keyword Planner

Google Keyword Planner is a fundamental tool for many SEO professionals, primarily due to its direct integration with Google Ads. It provides valuable data on keyword search volume, competition, and forecasts for paid search campaigns. While designed for Google Ads users, it’s widely used for organic keyword research due to its accuracy and reliability.

The tool offers basic keyword discovery and suggestions functionalities, making it a great starting point for beginners. However, it may need more depth of insights from more advanced tools like SEMrush or Ahrefs.
