Rocket blasting off

Finding topics for your blog can be a daunting process for the beginner, but fear not, there are some awesome tools out there that can point you in exactly the right direction.

Let’s get started.

  1. Google Trends
  2. Answer The Public
  3. Exploding Topics
  4. Buzzsumo
  5. SEMRush

1. Google Trends

Google Trends Homepage

Google Trends has been around for many years and can certainly turn up some interesting data. There are however, issues with overall accuracy.

A recent study showed that the search volumes can be reasonably accurate at a country level but certainly not at a more granular level, like cities, for example.

“In the considered timespans, Google Trends has proved to be reliable only for surveys concerning RSVs [number of searches] of countries worldwide.”

It’s a good place to start your investigations, however other studies have also found that the accuracy of Google Trends data was simply not reliable, especially for smaller search volumes.

Trends can be useful to show you what are very popular searches and now even includes a ‘real time search trends’ section.

This can even be broken down by category so for example you can see popular sports searches over the last 24 hours broken down by event, as well as any related queries.

Take the numbers with a pinch of salt, though.

2. Answer The Public

Answer The Public Homepage

Answer The Public is a really good tool for discovering question phrases that exist within a particular topic, rather than unearthing currently popular topics.

It’s very good, however and can certainly help to pick up on areas of a topic that you may not have previously considered.

Answer The Public Visual Search Results

There is a pro version (from $99) which gives search volumes but you can probably get similar data from something like SPYFU at a lower cost.

The Answer the Public pro service also includes a tool for brand monitoring alerts.

Once you have your popular topic that you plan to write on, this is the perfect tool to make sure you are covering all the angles.

From the homepage you can just enter a search term and hit the search button. It creates some pretty visualisations of topics (above), but you may find the ‘data’ tab easier to use.

It will also allow you to download the whole list in an easy to use CSV file like this:

The free service only gives you three searches though, so use them wisely! Or fire up a VPN and a different browser.

For free, this is a great research tool that you should definitely make use of.

3. Exploding Topics

Exploding Topics Homepage

Exploding Topics was created by Brian Dean, this tool is intended to detect brand new product trends for investors as well as identifying relevant keywords that can be used for content marketing.

You can view the data from 30 different categories or you can search the database.

The tool is aimed at entrepreneurs but definitely can be of use to a content marketer for basic research. It is apparently used by the likes of Google and Microsoft.

Some data is held back from the free version as you can see from this screenshot of the ‘Crypto’ category.

Nevertheless, the free functionality allows you to identify new trending areas and keywords that you may not have been aware of otherwise.

4. Buzzsumo

Buzzsumo homepage

Buzzsumo is one of the most useful social media marketing tools you’ll find.

Imagine being able to sift through any niche of the Internet for popular content, and see it broken down in a list by the amount of Facebook shares or Tweets that each page got.

That’s what you can do with Buzzsumo. It is indeed the sumo wrestler of trending topic research.

This unique functionality means that you can get the exact research on what sort of content is actually working in your niche.
