2. Database size and accuracy<\/h3>\n\n\n\n The cold, hard truth when it comes to SEO and keyword analysis tools is that no matter how sophisticated they are, they can only be directionally useful and reliable. You can\u2019t expect all tools to be 100% accurate as even Google\u2019s very own tools don\u2019t guarantee pinpoint accuracy. Keyword tools, however, can help you discover and validate your topics and prioritize keywords according to your best interests. Take data with a grain of salt, but use it as a good ballpark metric to drive your SEO campaigns.<\/p>\n\n\n\n
SEO tools mainly rely on scraping Google to generate data, and their output depends on the power of their scraping tool and the size of their database. That\u2019s why you may have noticed how data varies from tool to tool.<\/p>\n\n\n\n
For example for search volume, there\u2019s a disparity in terms of data among the 3 tools.<\/p>\n\n\n\n
For the keyword aba therapy:<\/p>\n\n\n\n
Semrush shows a search volume of 110,000:<\/strong><\/p>\n\n\n\nAhref displays 101,000:<\/strong><\/p>\n\n\n\n\n\t\t\t\n\t\t\t\t\n
\n <\/path><\/svg>\n <\/button>\n \n
\n
<\/div>\n <\/div><\/figure>\n\n\n\n
Keywords Everywhere shows 135,000:<\/strong><\/p>\n\n\n\nNow, how do these best keyword tools generate data?<\/p>\n\n\n\n
\nSEMrush <\/strong>claims they have their own trusted data providers and machine learning algorithms to feed data into their databases\u2026<\/li>\n\n\n\nAhrefs <\/strong>states that they have their own search crawlers working 24\/7\u2026<\/li>\n\n\n\nKeywords Everywhere<\/strong> uses data from Google Ads Keyword Planner, but you can also go to the settings page if you want to source data from both Google Keyword Planner and Clickstream.<\/li>\n<\/ul>\n\n\n\n\n\t\t\t\n\t\t\t\t\n

Again, just use keyword tools as barometers to assess your performance relative to the competitors. Besides, keywords are moving targets, making it even harder to achieve precise figures.<\/p>\n\n\n\n
You can cross-reference data to make informed decisions, but if you want to benchmark your website against your main competitors, you\u2019d want to use the same keyword search tool to compare a set of websites. <\/p>\n\n\n\n
Combining data from SEO tools with webmaster tools like Google Analytics and Google Search Console<\/a> will also help you get a more holistic view of your website\u2019s performance.<\/p>\n\n\n\nAlthough database size doesn\u2019t necessarily guarantee quality, it can be a factor worth looking into. In terms of database size, here\u2019s where the three best keyword research tools stand:<\/p>\n\n\n\n
\nSemrush covers 25.6 billion keywords in <\/strong>808 million domains, processing 500TB of raw website traffic data from over 190 countries and regions.<\/li>\n\n\n\nAhrefs has a keyword database of 28.9 billion keywords<\/strong>, covering 226 geographic regions.<\/li>\n\n\n\nKeywords Everywhere has a database of around 5 billion keywords for each country.<\/strong><\/li>\n<\/ul>\n\n\n\nSo how do we score the best keyword tools in terms of data accuracy? Let\u2019s see the numbers:<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\t\n
\n <\/path><\/svg>\n <\/button>\n \n
\n
<\/div>\n <\/div><\/figure>\n\n\n\n
Semrush and Ahrefs add up the total keywords for each country they support including duplicates, but Keywords Everywhere covers a solid volume of 5 billion keywords per supported country. <\/p>\n\n\n\n
Plus, we aggregate data directly from Google Keyword Planner, which is still the most accurate keyword tool in the world. In any case, Semrush and Ahrefs are still very strong seo keyword tools that continually get better.<\/p>\n\n\n\n
3. Keyword relevance and freshness<\/h3>\n\n\n\n As mentioned, a large database doesn\u2019t automatically equate to data quality because an outdated one will only render ineffective results. Keyword relevance and freshness matter just as much, if not more.<\/p>\n\n\n\n
A huge and updated keyword database is the sweet spot. This is how often each keyword research tool updates their database:<\/p>\n\n\n\n
