My Favorite SEO Keyword Tools

Text Optimizer is a Chrome extension that analyzes search snippets and creates a list of terms to include on your page. Simply load your page in Chrome and click the tool icon to evaluate all or part of your text. It’s another option to optimize content — for Google and Bing. The web version is premium, but the extension is free.
A free tool called AlsoAsked identifies follow-up questions from a query, offering a view of the possible buying journey.

Autocomplete

Google’s “Related searches” helps users narrow their queries. The section is typically at the bottom of the search result pages for all devices.

Autocomplete is built-in to Google.com’s search and leading browsers such as Safari and Chrome. Based on popular queries, autocomplete predicts what a searcher will type next.
I’ve listed my favorite keyword tools from Google in this post. I’ve also included helpful third-party tools with free and premium versions. All of these are in addition to the free Google Trends and Google Search Console, essential components of any keyword toolbox.
The free version shows all the predictions from your primary keyword. It also allows you to filter by a common word, exclude results containing a word, and generate predictions in the form of questions.

However, the free version does not allow downloading the lists or viewing metrics such as search volume and competition. Nonetheless, it’s beneficial in my experience for generating ideas and optimizing content. (Another tool, SearchVolume.io, provides for free the number of searches — for up to 800 phrases in bulk.)
