Free Keyword and SEO Tools for 2021

[Kurt]

Here's a list of free keyword tools and tips for a variety of resources. Some of these free resources have limited free use so be sure to check before you use them up.

Bookmark this page: Instead of having a bunch of browser bookmarks I put my favorite keyword related tools here. You can do the same and add your own favorites and comments below.

 
Keyword.io - I often start my searches here.  Generally uses "suggestions" from the drop down options for Google, YouTube, Bing, Amazon, eBay, Play Store, Instagram, Twitter. I like it because of the filters and the ability to filter for questions.

QuestionDB - Questions folks asked on Reddit.

AnswerThePublic - You only get two free searches a day now. Make them count.
https://answerthepublic.com/


AlsoAsked - These are questions people have asked...possibly the main benefit is actually for copywriting. I tried it and the first time it worked great so I created a free account. I've tried 6-7 searches since and it just "hangs". Will try again.

WordStream - IMO the closest to a real "LSI" (co-citation) tool. Instead of just giving lists of keywords with the same root word, it gives related words too that don't share "root" words.

LSI Graph - Also includes "semantically related" keyword phrases along with some other good info. Really good for creating web pages about a subject.

Keyword "Sheeter" - Creates BIG lists of keywords based on the same root keyword:
