Keyword tools provide data on keywords for specific search engines. But none of the data is correct, and you can tell because each keyword tool will give you different data for any given keyword. Instead, keyword tools guess on keyword data. In order to get accurate data, a tool would need to access the search engine’s database (not just API) on a CONSTANT basis and pull every keyword ever all the time. No tool does that. In other words, the only companies that know keyword data exactly are the search engines themselves. And that’s valuable data that they wouldn’t just give up to any keyword company. Think about it, if you were Google, would you rather give out your keyword data for $10 a month, or free to developers so they can charge $70? It just doesn’t make sense that search engines are giving keyword data away. But let’s assume keyword data on these tools is correct. Or at least somewhat accurate. Are they worth using in the first place? I would argue not really. Search engines are sophisticated enough now that they can decode intent. Basically, when you search beard trimmer, and a company is advertising a beard clipper, your search engine knows they’re the same thing. So it’s not about getting the exact keyword correct.Instead, bloggers should search focus on TOPICs instead of keywords, and CPG companies should focus on conversion. And as long as your content is thorough enough and helpful enough, you will rank.
