Profitable Blog Topics: Easy Ways to Find Them

By 7min read

An easy, step by step approach to finding profitable blog topics.

There are two ways of understanding the term “profitable blog topics” – either as terms to base a blog around or ideas for blog posts that will encourage people to buy or listen to what you have to say. Here I explore easy ways to identify both interpretations.

Profitable blog topics for a blog or website.

It is always easier to start by seeing what other people have done before you and whether they have tested the market for profit before you.

Every profitable area fits into one of three main areas:

  • health
  • weath
  • relationships

If I take the first area, health, for example. Health encompasses so many different areas it can be overwhelming. I used to be a nurse so I can think of so many things! However, if I focus on diet as a health topic, then types of diet such as ketogenic, low carb, vegan, pescatarian are all possible areas to focus upon, some may even be potential profitable areas.

Why the need to consider profit? I am an entreprenuer at heart so I want to think about how I can help PLUS how I can create a business at the same time. Whilst the primary focus for me is always helping, I would like to see some rewards at some stage 🙂

To continue then with the diet scenario, if I then break diets down further to, for example, low carb diets for different groups of people, I can then think of groups such as young mothers, men who want a six pack stomach, post-menopausal women – if you were to search for these in any of the areas below and found any of the following:

  • ebook,
  • book,
  • course,
  • mini course,
  • coaching
  • membership scheme,

then you would have found some profitable blog topics. The reasoning being is that if there is a course, ebook etc targeted at that niche or group, then there are people interested enough to want to buy that product. If they are interested enough to buy, then they are seeking a solution to their problem. This also means that they will be interested in content discussing and helping them find solutions.

Sometimes though, it is easier to think a little more broadly to start with. I want to know if a niche by itself is profitable.

Once I have an idea, I then head over to the following sites to check to see if I can find any of the above signs of profit.

For ease, and to explain simply how this works, I am going to focus on the keyword term “low carb diets”.


Amazon is a huge, powerful search engine so a very obvious place to start. Using the key term “low carb diet” in Books, I find the following suggestions:

  • low carb diet books for weight loss
  • low carb diet books for diabetics
  • low carb diet for beginners
  • low carb diet shakes
  • low carb diet cookbook

And I could go on…. but already there are some ideas around which to base a blog or write a blog post. If I go to the first option above “low carb diet books for weight loss”, there are many books for sale.

Next I need to look at the first book and check its ranking on Amazon. Amazon has a ranking structure that indicates how popular niches are and whether a book is a bestseller or not. If the book has a rank of 150,000 or less and there are several books in this niche, then this is a market worth exploring further. B y scrolling down the page, I find this information:

This book ranks very highly in all books as well as ranking for #278 in Weight Control Nutrition. It indicates that it is in a niche that is popular and there is constant demand for it. If I look at the other books that also came up for ‘low carb diet books for weight loss’, there are similar rankings all indicating to me that this is a very popular niche.


Next stop is Google search engine. By adding ‘Low carb diet’, 240,000,000 pages are returned. A very popular niche! But don’t panic. This is excellent news at this stage.

By retrying the term in the search bar with apostrophes around it “low carb diet” , 11,400,000 pages are returned: these reflect the phrase match term. It is still very popular which is still good. This means that there are this many pages that have this term mentioned with the words in this order i.e. a phrase.

If I then add on words such as “ebook”, “course”, “assistance” and always using the brackets, I get the following results:

  • “low carb diet ebook” returns 41,400 pages
  • “low carb diet course” returns 5,580
  • “low card diet assistance” returns 5 pages.

It seems to me that people are using the above phrases to seek help. Over 41,000 pages mention a low carb diet ebook. There is obviously a demand for this. But these low numbers indicate to me that there is a opportunity for me to focus on this niche.

Whilst I am here on Google I make sure that I look out for paid ads. However, I see no paid ads for this search term. This does not mean that it won’t be a competitive market or that there will not be people willing to buy. Being overweight is an emotional problem as well as a health problem. If we think about the three key areas that I discussed above, that people buy in to (health, wealth and relationships), then ‘low carb diets’ for example could be exactly the help that someone needs as there is a chance that there will be overlaps between the three groups.

Here’s my thinking. If someone is overweight, it could be affecting their health firstly but also their relationships. Or it could be that their health is affected be their extra weight and this in turn means that they are no longer able to do their work. There could be long terms concerns about income. Losing weight is always personal and an appreciation, in this example, that there are many aspects to the problem (being overweight) could assist in developing a blog theme and blog posts.

Google Trends

I love using Google trends. It is free tool that throws up all sorts of fascinating data – in real time but also historically. More importantly, it predicts how the trend is going to continue. It is possible to split the data into all web searches, youtube searches, news search and google shopping too. You can find anything from a very recent news item to ‘low carb diet’ and everything in between. It really is a goldmine of information.

The data for a search term can also be shown by region and different time frames. So, if I use “low carb diet” then here is the graph represented for Germany (for example). This shows a pretty consistent use of this keyword over the last year with a predicted trajectory upwards.

profitable blog topics

This data in Google trends also tells me that it is a subject that has constant demand so there will always be a steady audience. It is easy to play around with and you can easily see if there is a constance demand for information (which there is here). If so, then there is a constant market or people consistently seeking information to help them.


Udemy is a search engine for courses, in effect. It is a huge website where people can upload courses to sell. Each course is then rated so you can see the feedback and whether it was recommended.

It sells courses on all sorts for topics and can be very helpful in seeing what courses are selling, what they are about and how many people have taken them. These courses have all been uploaded by people wanting to sell a course in their area of interest.

By entering the keyword “low carb diet”, several courses come up. A quick search around shows that one course in particular has had 715 reviews. This shows a buying market for courses about losing weight. People are willing to spend money to learn about a low carb diets.

So when identifying profitable blog topics, the easiest place to start is to brainstorm a list of things that you know something about. Be as random as you like or as focussed as you can be. One by one, I would go through each item and perform the searches above. Start with two word keywords (eg. low carb) and then expand to three (eg. low carb diet) , then four (eg. ow carb diet books). Make lots of notes and follow the lateral thinking you find your mind takes. It will be amazing to see what you can find!

By the end of this process, you will have a clear idea about what your blog will be based upon
