This isn’t the only tool that mines Google Autocomplete. There’s also KeywordTool.io, but that restricts results to ~700 keywords. Infinite Suggest is another alternative. But, despite the name, it doesn’t seem to find anywhere near the number of keywords that Keyword Sh*tter finds. And there are tons of other Google Autocomplete miners, too. Google “google auto suggest tool” for more. There’s also this tool from SEOChat. It mines autocomplete suggestions from Google, Bing, Amazon, and YouTube.
SEMrush Keyword Research feature gives you tried and tested keywords that can help you in improving your website rank in Google’s and Bing’s top results. It also provides you with the value of these keywords in paid as well as organic search, and which top players are using them in their landing pages. There are ton of useful data outside Google Adwords.
In addition to the core tools that are part of SEMrush’s main package, the company has over the years introduced a few separate tools addressing various aspects of content optimization. Some of these tools are still in beta while others are not. Also, they require a separate subscription apart from the main SEMrush suite. Though currently they are free if you’re already part of the SEMrush ecosystem and using their tools. But some things could change later on depending on how well these serve users and what additional features are added.
