Social Media Keyword Research Techniques


You won’t see a lot of marketing gurus speak on this, but Pinterest is a gold mine for learning what consumers are searching for. Pinterest is a platform designed for creatives (or anyone) to share visual ideas and content. Pinterest’s search engine is unique to that of Google, Yahoo, and etc. 


The social network that slips under the radar many times is the ever-so impactful Quora. Quora is mostly a Q+A forum page with its own search engine. This helps with noting the proper phrases to be taken into account when writing your own headlines, permalinks, and meta descriptions. We dissected the platform and discussed how it could be used to generate blog topic ideas.

Quora is one of the most underrated tools for keyword research. For no money at all, you can create an account and use the community there for more insight into what questions people are asking and what topics are currently pressing. You can learn so much also by posing good questions to the public and receiving thousands of responses in an instant.

Paid Options for Keyword Research Pros

One of our personal favorite SEO tools to use ourselves is SEMrush and for many reasons. Though there’s a free version of the tool, it’s pretty limited. But the paid tiers offer SEO tools that will take your keyword research, content writing, and content marketing abilities to the next level. Some of SEMrush’s key tools include the Keyword Magic Tool, SEO Content Templates, and SEO Writing Assistant.
