I'm a marketing guy, a pizza enthusiast, and a San Francisco resident. I co-founded Growth Marketing Pro and the industry-leading AI writing tool, GrowthBar.

How do you come up with blog topics?

There are lots of ways to come up with ideas to write about for your site or blog. This is commonly referred to as keyword research.

According to Hubspot, keyword research is “the process of finding and analyzing search terms that people enter into search engines with the goal of using that data for a specific purpose, often for search engine optimization (SEO) or general marketing. Keyword research can uncover queries to target, the popularity of these queries, their ranking difficulty, and more.”

How to come up with these keywords, or blog topics?

Brainstorming: This is as simple as it gets. Get a piece of paper or open a spreadsheet and start coming up with ideas you think that you could rank for.
Using the content cluster model: The content cluster or topics cluster model is when a blog or website has several main-topic pillar pages, and then multiple content pages relating back to each of the pillars and each other. The content cluster model can make it easier to brainstorm blog topics because it organizes all your content into a few main topics. While a lot of ideas are always important, you want to make sure they stay relevant to your products and clients, and that’s what the cluster model help writers do.
Mapping the customer journey: Diving into your customer journey is a great way to come up with inspiration for your blog because it helps you identify the questions they’re searching for. The more you can get into your potential clients’ heads, the better you’ll be at coming up with new blog topics that they’ll be searching.
Spy on your competitors: A good way to get some new inspiration for your blog is to check out your competitors’ blogs. What are they trying to rank for, and would those ideas work for your ideal customer? Just make sure you’re still choosing topics that work for your specific audience, and try to stay away from posts that have been written multiple times. You don’t want to write a blog that has to compete with every other blog on the Internet. Keywords with a high search volume and low competition are the “holy grail” of search engine optimization.
Blog topic generators: And of course, the easiest and fastest way is going to be blog topic generators.

What is a blog topic generator?

But simply, a blog topic generator is a platform that automatically comes up with topics for an article based on keywords or phrases you provide.

For example, if I wanted to come up with blog topics for webinar tools, I would type that concept into whatever blog topic generator I’m using, and it would provide a wide array of options for me to write about.

If it’s a great blog topic generator, the ideas they come up with should be:

Unique and interesting–not just “what is” or “how tos”
Relevant to your keyword
Long tail and short tail options
Accessible–you should be able to write a full blog post on it
Inspiring
Almost endless!

Now what are the best blog topic generators to use?

One of the leading marketing, sales, customer service, and CRM platforms, Hubspot has a free blog ideas generator for marketers. To use this tool, all you need to do is input up to five nouns, and you’ll get a bunch of blog ideas back.

It’s not perfect…you’ll need to edit the titles and some might not be totally relevant. But, this tool does generate ideas that you probably wouldn’t have otherwise have thought of, and it’s free (minus your email address), so it’s worth trying.

Jasper.ai

Jasper.ai (formerly known as Jarvis, formerly known as Conversion.ai) is one of the best content generators on the market. Their AI instantly generates high-quality copy for almost endless options beyond your marketing classics, including a “explain it to a child” setting, real estate listings, and Quora answers.

And of course, blog topic idea generation.

What it does:

Like most blog topic generators, Jasper takes your input and then provides several blog topic ideas for you to use. However, instead of putting in keywords, you can input your company name, product description, target audience, and the tone of voice you want your post to be written in (which is always fun).

From that information, Jasper offers you various blog ideas, which you can either star or delete to help with some machine learning. The goal is that Jasper takes your feedback about the blog topics and gets better over time.

As with Copy AI and some other full content production tools, the results are mixed. Sometimes the copy just doesn’t make sense — I’ve found it seems to output old years (ex: “2018”) in content generations.

Features:

Generates blog post topic ideas, as well as:

AIDA framework and PAS framework
Product descriptions
Content improver and sentence expander
Blog post outlines, intros, and conclusion paragraphs
Ad headlines and primary text
Personal bio or company bio
Marketing angles and ideas
Review responder

Pricing:

As of now, pricing is on a sliding scale per-word-per-month. Most users will find that between $79/mo and $149/mo should suffice for their content creation needs, but you can start at as low as $29/month. Their two plans, Starter and Boss Mode, have different features available depending on your price point.

Copysmith

Copysmith is a content generator specializing in producing copy for social media, ads, product descriptions, meta tags, and other short snippets of content–including blog ideas. It’s a great tool for entrepreneurs and digital marketers with quick copy needs.

What it does:

Copysmith has many different templates depending on the type of copy you want to generate. Generally speaking, each template format is very similar; you add keywords and other relevant information, then their AI does the rest.

You end up with a list of short snippets of copy–in this case blog ideas. Each piece of copy is unique, so you can either use it or make some edits. The Copysmith team says their content is ready to deploy instantly in most cases but from my experience, I think you’ll need to make some edits to content before pushing any of it live.

Copysmith is great for any content creators or marketers who need a boost thinking of blog topic ideas–and lots of other copy too!

Features:

Instantly generate high-quality AI content
Various copy types available in addition to blog topics such as ads, meta descriptions, product descriptions
Original copy that will pass plagiarism checkers

Pricing:

There are three different monthly pricing plans:

Starter: $19/mo

Buzz Sumo is a relatively young content marketing tool allowing marketers to create content, monitor their branding, and discover new opportunities for growth. Buzz Sumo offers content discovery, content research, influencer research, and more.

The “more” includes their “topic explorer” feature that provides not only blog post ideas, but also real content examples to get you inspired.

What it does:

Buzz Sumo’s Topic Explorer suggests related topics, popular content, and a key question for any subject you write about. The Topic Explorer uses artificial intelligence to allow content creators to expand their reach (and blog post ideas) to new subject areas.

The Topic Explorer’s question suggestion is curated based on relevance using popular articles previously written about this topic and related keywords people are searching using Google’s algorithm. Once you enter your topic into the search field, you receive a word cloud and a series of related topics, sorted by relevancy, with the most relevant topics the largest and most central.

Pick and choose what topics you think will be resonate with your audience, and start writing!

Copy.ai

Copy.ai is an automated creative tool that generates marketing copy in seconds. Their tagline is, “Introducing the end of writer’s block,” and this message will be music to the ears of copywriters worldwide. It’s similar to Copysmith, but I’ve found its content generations to be a little less reliable.

Built on powerful AI, Copy.ai generates ad copy, social media content, website copy, blog content, and any other form of digital copy. It has the most styles of copywriting of any tool. You can create email content, Facebook Ad content, Google Ad content, sales outreach copy, and much more. It doesn’t specialize, so it’s great for an all-around digital marketer.

It has more content “types” than any other tool — they have north of 90 types of content generations.

What it does:

Copy.ai generates all kinds of digital copy, including blog post ideas. All you have to do is select the type of copy you want—such as a blog intro, description, ad copy—fill out some basic details about the piece, and Copy.ai will generate the copy.

Knowing that you need content is the easy part. Producing that content is the hard(er) part. Blog topic generators can save you literally hours of time spent researching and brainstorming by providing hundreds of relevant ideas with the click of a button.

And an extra bonus if the topic generator comes with other handy tools, like GrowthBar’s keyword research and rank tracking, competitive insights, blog outline and paragraph generators, and more.
