Do you want to create the next best blog on your topic?

You need a blog if you want to use content marketing to increase your online presence and attract customers by getting to the top of a search engine results page for a high traffic keyword.

A blog keeps your website current (that way your website visitors know the business is still moving forward and not been abandoned)

It also gives you a way to reach out to potential customers and tell them about new features, products, and services.

An excellent blog may even get shared and attract your target audience without you lifting a finger, bringing in new visitors.

Of course, for all this to work effectively, you need to write high-quality content. You need to know what topics are trending in your industry and what topics your potential clients want to learn more about.

So how do you know what topics are trending or important to your customers? You’re going to have to do a little research.

Here are the 12 best tools for uncovering blog post ideas that are trending and are topics your readers want to learn more about. If you use even a couple of these tools, you’ll never sit around wondering what your next blog post will cover.

1. Google Trends

It’s essential to stay on trend with your blog content. Set up industry notifications on your phone or desktop and keep up on the news to learn about current affairs in your industry. You can do this by searching Google Trends.

For example, when you type ‘shoes’ into Google Trends, you’ll see that you get these results (at least at the time I’m writing this):

The keyword “Kyrie SpongeBob shoes” comes up first. When something is trending, it’s vital to write the content right away before the topic gets old and cold. So this might make a good topic phrase to write about or at least include in an article if you’re covering the topic of shoes.

Browse already existing articles before you write to research the competition. You should also attempt to spin your article a different way to make it stand out compared to the other content. If you write the same thing as everyone else, you won’t look unique.

2. Answer the Public

Answer the Public is another keyword tool that can be used as a content idea generator, this one also free.

You start by entering your keyword and the tool will find all the questions people commonly ask about that keyword. It’s all organized into a cool diagram like the one shown below:

In this example, questions like “can shoes be recycled” and “will shoes expand” show up in the results. Those would make for good blog post topics to write about if you’re in the shoe industry.

Answer the Public also offers keyword options like prepositions, comparisons, alphabeticals, and related. You can find a lot of trending blog topic ideas by using this tool.

3. Buzzsumo

BuzzSumo searches the internet for the most talked about topics in your industry for you. With Buzzsumo, you don’t have to guess what people want to learn about – it does the work for you.

This tool will give you plenty of ideas and then sort them by popularity online. It also comes with several different search filters to help you narrow down your results by dates, sources of information, and more.

Take a look at the image below, also using the keyword “shoes”:

Buzzsumo scans a tremendous amount of articles and social media posts to get an idea of what people are discussing. They’ll even analyze responses to social media posts. They tell you what’s trending in general, or you can select your industry.

This tool follows everything from business to tech to health. There is a fee for the service, but you can try it free for seven days by entering your email address.

This online tool was created as a blog topic generator, but you can even use it to scan for the best blog post title options. Mix and match from the top content on your topic to come up with the best title.

4. Quora

Quora is an online platform where random people can ask questions on a wide variety of topics. There are sure to be questions regarding your industry as well.

Scan the site for specific keywords to see what questions people have asked on your topic like in the screenshot below:

As you can see, the question, “what are the best running shoes” is a popular topic with some answers. You can get a lot of trending content ideas from Quora as it’s an incredibly popular online site.

Even if there’s already an answer to the question on Quora, you may be able to answer the question in more detail in a full blog post.

5. Ubersuggest

Ubersuggest can give you keyword ideas as well as content ideas (similar to Buzzsumo). It’s well worth consulting this tool to help you find trending topics to add to your mix of ideas.

The screenshot below shows some popular topics on shoes as shown by Ubersuggest:

6. Google related searches

You may think you have the perfect keyword. However, some people will phrase the keyword slightly differently. To reach these people, you want to use Google’s related searches feature to get ideas for additional keywords and content topics.

All you need is Google. Search for your particular keyword. Under the search results, you’ll see several related topics like shown below:

You can also look at the “People also ask” box that is mixed into the search results as well as shown here:

These are often popular, trending questions. Include these keywords and questions into your content. In some cases, you might even come up with a brand new idea for a topic.

7. Keyword Tool (autocomplete)

One thing to mention is using Google (or another search engine), you don’t even need to completely type in your keyword to get new ideas for keywords and blog topics.

Start typing in your keyword and see what Google suggests as you type. It likes to direct people to what they want before they even finish typing as shown in the screenshot below:

google autocomplete

Google comes up with these suggestions based on what is trending and popular so pay attention to the recommendations. You might see a specific keyword you didn’t think of previously.

You don’t always need a sophisticated marketing tool to learn what you need to know. Sometimes, Google can let you know right from the search bar.

8. Twitter

Social media is a powerful tool nowadays. Use your Twitter account to ask open-ended questions to your followers. You can also use polls to ask people what they want to know about your industry.

Pay attention to any hashtags that may be trending, too. Stay active and connect with other people in your industry so that you will be one of the first to know about trending topics, news, or interesting blog post ideas people want to learn more about.

9. SEMrush

SEMrush is another online marketing tool. This one allows you to analyze over 16 billion keywords. It will give you trending topics in your industry, but it does a lot more than that. It will also provide you with ideas on how to improve your SEO.

Here’s a screenshot of the SEMrush Keyword Magic Tool:
