Instantly cluster keywords
Group keywords by Parent Topic or common terms in a jiffy. No more time wasted skimming keywords that all mean the same thing.
With most keyword clustering tools, you need to wait quite a while for your keywords to be grouped into clusters. But Keywords Explorer has its own clustering logic that groups keywords instantly, saving you precious time.
Analyze any keyword in detail: estimate ranking difficulty, see search volumes, true traffic potential, and review SERPs.
Estimate ranking difficulty
Use Keyword Difficulty (KD) to understand how hard it will be to rank in the top 10 organic search results for a keyword. The lower the score, the easier it is to rank for.
Estimate ranking difficulty
Use Keyword Difficulty (KD) to understand how hard it will be to rank in the top 10 organic search results for a keyword. The lower the score, the easier it is to rank for.
We calculate the KD score based solely on the average number of backlinks to the top-ranking pages.
Get search volume trends
Pick keywords with the highest potential using past, present and future search volume estimates.
Get a breakdown of search volume by country
Quickly check country-specific search volumes and prioritize which countries to target with your content.
Gauge a topic’s true search traffic potential
Our unique Traffic Potential metric gives you an estimate of how much search traffic you might get from ranking #1 for a given keyword.
This number is taken from the page that currently ranks #1 for a given keyword.
查看您的目标关键词的“父主题”
A single page can rank for hundreds of related keywords. Use Parent Topic to see if you can rank for your keyword while targeting a more general topic instead.
Review the current SERP like a pro
Analyze top results for your target keyword. Analyze the SEO metrics for each page like backlinks, organic traffic, and traffic value to better understand why these pages rank where they do.
Check the historical rankings of the top-ranking results
Study the SERP volatility for a given keyword. The Position history graph shows you movements for the top 100 pages, so you can better assess ranking stability and the evolution of search intent over time.
See the full history of search ads for any query
Understand a keyword’s commercial value over time. The Ads position history chart shows you all the websites that have advertised for a keyword, along with their actual ad copy.
Compare mobile versus desktop searches
See how content is consumed and adapt accordingly. Device distribution shows the number of mobile versus desktop searches for a target keyword.
Target keywords skillfully. Use AI to identify search intent, compare SERPs side-by-side, and organize keyword ideas into lists.
Find “low-hanging fruit” keywords
Filter through high-difficulty keywords where a “weak” website ranks at the top. This is an indication that you might have a chance to penetrate the SERP too.
Cross-reference keyword ideas against keywords you’re already ranking for
Find keywords where your target website doesn't rank in the top 10 or top 100 search results. For those where you don’t rank at all, create new pages. For those where you rank in low positions, update the content.
Use AI to help figure out search intent
You no longer have to shoe-horn search intent into traditional buckets (navigational, informational, and all that). Let AI instead suggest what people are actually looking for when searching for a topic.
并排比较 SERP
Study SERPs for the same keyword on different dates to spot any ranking changes. You can also compare two different keywords to see if you should target them with the same page or separately.
Organize keyword ideas into keyword lists
Save and segment keywords into lists that you can conveniently pull metrics for with just one click.
See the organic share of voice (SOV)
Use the Traffic share by domain/by page reports to instantly see which domains or pages rank for these keywords and the percentage of cumulative traffic they’re driving.
Keywords are the foundation of SEO. Pick the wrong keywords, and you risk wasting lots of your time and resources.
