Discovering Trending Blog Post Topics for Free: A Strategic Guide for Content Creators

By November 16th, 2023No Comments7 min read

Creating a blog that captures the attention of a wide audience requires not just great content, but also a finger on the pulse of what’s trending. Identifying hot topics can be a game-changer for both new and seasoned bloggers looking to drive traffic and engagement. However, the challenge often lies in finding these trending topics without breaking the bank on expensive keyword research tools. In this comprehensive guide, we’ll explore how to unearth these gems for free, ensuring your blog stays ahead of the curve.

Understanding Keyword Research

Keyword research is the backbone of content strategy and SEO. It involves identifying the words and phrases that potential readers use to search for content online. By optimizing your posts with these keywords, you increase the likelihood of ranking higher in search engine results, thus boosting your visibility and traffic.

Traditional tools like Ahrefs and SEMrush have been go-to resources for keyword research, offering insights into search volumes, keyword difficulties, and competitive analysis. However, these tools often require a premium subscription and may not always provide the latest trends or the freshest keywords that have yet to show significant search volume.

Enter the world of AI-driven keyword research. Perplexity AI emerges as a promising free alternative, harnessing the power of artificial intelligence to deliver live and up-to-date information on trending topics across various niches. This real-time data is invaluable for bloggers seeking to capitalize on emerging trends before they become oversaturated in the market.

Step-by-Step Guide to Using Perplexity AI

To get started with Perplexity AI, navigate to their website and prepare to ask the AI questions related to your niche. For instance, if your blog focuses on gardening, you might ask, “What are some trending topics in the gardening niche of 2023?” The AI will then generate a list of current trends, such as “growing your own bouquets” or “climate awareness gardens.”

For travel bloggers, a query like “What are some trending travel hacks and tips?” can yield a treasure trove of fresh content ideas. The key is to be as specific as possible with your questions to obtain targeted results that align with your audience’s interests.

Analyzing Results for Blog Post Ideas

From the list provided by Perplexity AI, you can start brainstorming blog post ideas. Let’s say “creating cottage gardens” is among the trending topics. This could inspire a series of posts on designing a cottage garden from scratch, the best plants for cottage gardens, maintenance tips for this particular garden style, and even creative DIY projects for enhancing the charm of a cottage garden.

Once you have a list of potential topics, it’s crucial to validate their search potential. Ahrefs’ free keyword generator tool is a handy resource for this. By entering a keyword like “cottage gardens,” you can uncover related keywords, their search volumes, and keyword difficulties. This data helps you assess whether a topic is worth pursuing based on its potential to attract organic traffic.

Case Study: Keyword Validation

Consider the keyword “creating cottage gardens.” A quick search on Ahrefs might reveal a keyword difficulty (KD) of 39 and a decent search volume. Although the competition may be moderate, the interest in the topic suggests it’s worth exploring. To narrow down your focus, you can create a table comparing different types of cottage gardens, their unique characteristics, and the specific plants that thrive in each style.

Cottage Garden Type Key Features Recommended Plants
English Cottage Garden Abundance of colorful flowers and climbers Roses, Lavender, Hollyhocks, Foxgloves
Wildflower Meadow Natural, unstructured look with native plants Poppies, Cornflowers, Cosmos, Lupines
Cottage Courtyard Intimate garden space with containers Herbs, Dwarf Fruit Trees, Climbing Vines

This table not only provides valuable information to your readers but also helps you target specific subtopics within the broader category of “creating cottage gardens.”

Exploring Keywords with No Data in Ahrefs

Sometimes, Ahrefs may not have data for a keyword, which could indicate it’s either unpopular or very new. However, this doesn’t mean it’s not worth pursuing. For example, “ombre gardens” might not show up in Ahrefs, but a quick Google search could reveal minimal coverage on the topic. This presents an opportunity to become an early authority on the subject, potentially driving significant traffic to your blog.

Real-World Examples

Let’s delve into “drought-tolerant gardening”—a topic that’s gaining traction due to increasing climate awareness. While Ahrefs might show limited search volume, a search engine query can reveal a few blogs already covering the topic. This indicates a growing interest that you could tap into, positioning your blog as a go-to source for sustainable gardening practices. To provide readers with practical tips, you can create a list of drought-tolerant plants categorized by their water requirements.

Low Water Requirement Plants:

  1. Succulents (e.g., Aloe vera, Echeveria)
  2. Mediterranean herbs (e.g., Rosemary, Thyme)
  3. Agave
  4. Lavender
  5. Yarrow

Moderate Water Requirement Plants:

  1. California poppy
  2. Salvia
  3. Penstemon
  4. Red Hot Poker (Kniphofia)
  5. Verbena

By offering specific plant recommendations, you empower your audience to make informed choices when designing their drought-tolerant gardens.
