11 January 2024
To choose a blog topic that attracts and engages your audience effectively, think about your readers’ search interests and later find the right keywords. Here's how to research blog topics + some excellent blog topics research tools for finding out what’s currently trending with your audience.



Are you trying to figure out what kind of blog post topics will attract your prospects? Want to engage them with your web content but not sure how to research topics for your blog?


… no one understands your business better than you do, so you’re in a great position to identify the questions and concerns of your potential customers. Use your blog to address these issues, and they should flock to your website.

Here’s one piece of advice for researching blog topics: always think about your audience first.

Sounds simple, but how do you do it, especially if you’re short on time? If you can’t do detailed keyword research for your blog posts, give professional blog writing services a go. However, if you prefer to do it yourself, I’ve got some practical tips to help you get started:

  • Understand the questions and concerns of your potential customers. If you run a travel agency, you might address concerns such as How to Travel Safely with a Kid or Top Budget-Friendly Travel Destinations, and
  • Address these issues directly in your blog posts. For a financial advisor, this could mean writing articles like How to Start Investing with Little Money or Understanding Your Credit Score,
  • Choose a blog topic primarily on the needs and interests of your audience. A parenting blog might feature posts like Effective Ways to Manage Toddler Tantrums or Balancing Work and Parenting.
  • Try to engage readers using blog topics relevant to your business expertise. As a tech company, you could write posts like The Future of Artificial Intelligence in Everyday Life or 5 Essential Cybersecurity Tips for Small Businesses.
  • In the block titles use hand-picked keywords to maximize the reach of your posts (more on that below). For a gardening blog, keywords could be “sustainable gardening practices,” “indoor herb gardening,” or “seasonal planting guide.”
  • Use various topic research tools to discover subjects that your readers find interesting.

Speaking of which…

Free & Paid Blog Topic Research Tools

The below blog topic research tools are arranged in random order.

STEP 6: Create blog posts that cover these new topics. Try to offer something different or more detailed than your competitors. Don’t forget to give a new perspective to the discussed topic, and show your expertise and experience to win those extra points for E-E-A-T.

6 Quick SEO Tips for Increasing the Reach of Your Blog Posts

When you have your keywords and blog post ideas ready, you also need to know how to write content that ranks high. This involves using your keywords effectively and making your posts both interesting and useful for your readers.

Good content is easy to read and more likely to show up in search engine results. Below, you’ll find a table with straightforward SEO tips. These tips are key to writing content that not only engages your audience but also performs well in search engine rankings.

SEO ElementTipExample
TitleStart your post’s title with the main keyword.Title: “Mountain Biking Basics: A Beginner’s Guide”
First ParagraphUse the main keyword in the H1 header and within the first 50-100 words.First paragraph includes ‘Mountain Biking Basics’ within the first 100 words.
Headers and DescriptionsSpread similar keywords in H2 headers, the meta description, image alt texts, and throughout the post.H2 header: “Choosing the Right Mountain Bike”, Meta description includes mountain bike types
Header OrderStick to using headers in sequence. Use headers from H1 to H3 mostly.Start with an H1 header, followed by H2, and then H3 if needed.
Emphasizing TextUse bold or italics to highlight important parts for readers, and for keywords important for search engines.Bold: “Important safety tips”, Italic: “trail riding techniques”
ImagesName images using keywords, separated by hyphens, and include keyword-rich alternative descriptions.Image name: “mountain-bike-trail.jpg”, Alt text: “Rider on a mountain bike trail”

When you handle basic SEO optimization, there is another pretty important thing – actually two things – related to technical SEO that influences the discoverability of your blog content. I’m talking about Categories and Tags.

Categories and tags on the blog help organize your content and make it easier for readers to find what they’re interested in. Also, it helps bots understand what the content is about. Think of them like labels or chapters in a book:

  • Categories: They are like the big chapters of your blog. Each category groups together posts on a similar topic. For example, on a cooking blog, you might have categories like “Desserts,” “Vegan Recipes,” or “Quick Meals.” They help readers quickly find the type of posts they’re looking for.
  • Tags: Tags are more specific than categories. They’re like the index at the back of a book. Tags highlight specific things mentioned in your posts, like “chocolate,” “30-minute meals,” or “gluten-free.” They help readers find posts that mention specific items or themes they’re interested in.

Using categories and tags makes your blog more SEO- and user-friendly. Readers can easily browse through related posts or find specific topics they’re interested in, which makes them more likely to stay on your website longer and explore more of your content.

  1. Very useful tips. Personally, I also get inspiration from the “people also ask” section on Google and Quora – you can check what answers your audience search for 🙂

Leave a comment


1. How frequently should I post on my company blog?

The more frequently you’re able to provide users with valuable content, the better. However, it’s important to publish more or less regularly. Don’t write entries in bulk, remember that quality matters. Publish on the same days, for example on Tuesdays and Thursdays, so that people visit your blog regularly. You can also inform them about new content in the newsletter.

2. Will my new blog entries be automatically displayed on Google?

It’s determined by a number of factors such as your domain authority, internal linking and many more. If you want to make sure that Google indexes your entry faster, provide a link to it on your homepage. You can also use Google Search Console. Enter the link into the box for checking all URLs and then click “request indexing”.
