3. Finally, there's just good old research through trends and news. Google Trends, keeping up on industry news of the business, and even newsjacking (if there are relevant topics). These all require different resources depending on the business, but once you find the leaders in their news you can not only leverage them for keyword research but also glean insights into how you can become an industry leader yourself (and dominate SEO).
This is another common reason people won’t get Long Tail Pro. Their stubbornness can stem from many reasons – including the two mentioned above. Too stubborn to pay for it (can be confused with too cheap to pay). Or too stubborn to learn about the benefits. But the main reason is that lots of people actually think that they are better off without Long Tail Pro. Either they do their keyword research the free (hard) way which takes a LOT of time and knowledge and usually isn’t very effective. Or they use a different keyword research tool which they think is better. Let me just tell you – there is no better or more effective keyword research tool than Long Tail Pro. More than 70,000 marketers can’t be wrong and over the past few years Long Tail Pro has become the standard when it comes to keyword research tools.
Keyword research is a practice search engine optimization (SEO) professionals use to find and research alternative search terms that people enter into search engines while looking for a similar subject. Search engine optimization professionals research additional keywords, which they use to achieve better rankings in search engines. Once they find a niche keyword, they expand on it to find similar keywords. Keyword suggestion tools usually aid the process, like the Google Ads Keyword Planner, which offers a thesaurus and alternative keyword suggestions or by looking into Google Suggest.[1]

The limit on manual keywords could be higher.  I personally wish we could input 10,000 keywords at a time, instead of 200.  However, I understand the costs that Long Tail Pro has to maintain each time a new manual keyword is input.  Not a deal breaker, I just wish the limit was higher. (To be fair, I don't think most keyword tools have a bulk manual option at all).
