Key Criteria For Choosing A Free Tool
When evaluating free tools to look for keywords, search trends and topics, keep an eye on:
- Does the tool provide actual keyword suggestions (seed → suggestions)?
- Does it show search trends or volume (even approximate)?
- Does it help surface related topics or questions people are asking?
- Is it easy to use and does not lock you into a heavy paid scheme immediately?
- Does it support your content platform (blog, YouTube, etc.) or multiple search engines?
Top Free Tools You Should Try (2025 Edition)
1. Google Keyword Planner
This is one of the most trustworthy free keyword research tools because it comes directly from the search engine giant. While it’s built primarily for advertisers, bloggers can also use it to gather keyword ideas, get approximate search volumes and gauge competition.
How it works: You sign in to a Google Ads account (which can be free), navigate to Keyword Planner, input a seed keyword or your website URL, and it will generate keyword suggestions, monthly search volume ranges and competition levels.
2. Google Trends
Want to know which topics are rising or fading? Google Trends shows you how search interest evolves over time. You can even filter by region (e.g., Malaysia) and check trending queries. For example: Google Trends United States
How it works: Enter your keyword or topic, optionally set region/time period, and view interest graphs. Compare multiple terms to see which is gaining momentum.
3. Ubersuggest (Free Version)
Created by Neil Patel, Ubersuggest offers keyword suggestions, estimated search volumes, SEO difficulty scores and content ideas, even in its free tier.
How it works: Enter a seed keyword; the free version will furnish lists of related keywords, their estimated volumes, CPC and difficulty levels. Use this to pick keywords where you have a chance of ranking.
4. AnswerThePublic
This tool visualizes search queries people are asking (questions, prepositions, comparisons) related to your seed keyword. It’s excellent for content brainstorming and find long‑tail topic ideas.
How it works: Enter a keyword and it displays a “search cloud” of questions and phrases. Export the results or jot down the most compelling ones and turn them into blog post topics or headings.
5. Soovle
A simple but powerful tool that aggregates autocomplete suggestions from multiple platforms—Google, Bing, YouTube, Amazon, Wikipedia, eBay. Great for cross‑platform keyword discovery.
How it works: You type in a keyword and Soovle displays real‑time suggestion bubbles from multiple engines. You can export the list and use it for ideas across different content channels.
6. Keyword Surfer (Chrome Extension)
This is a browser extension that overlays keyword volume and suggestions directly into your Google search results—instant keyword insight without switching tools.
How it works: Install the extension, search a keyword on Google, and you’ll see search volume, related keywords and even “suggested articles outline” right on the results page. Ideal for quick research while browsing.
7. YouTube / Video Trends Tools
Even if your primary platform is a blog, checking video trends can give you early signals for topics. For example the free “YouTube Trend Finder” tools (e.g., by Maxsemo) show trending searches and topics within YouTube.
How it works: Use a YouTube‑trending keyword tool, filter by region/category, and see what topics are heating up. Example: People used YouTube autocomplete with “how to” to discover popular queries.
8. Bing Webmasters Tools
While not purely a keyword research system, Bing Webmaster Tools gives you search performance data for your site from Microsoft’s search engine. It’s useful for a holistic view of site health and search visibility beyond Google.
How it works: Verify your blog, and you can access indexing status, search keywords, click metrics and more from Bing’s side. This gives you an alternate data view and may highlight opportunities Google data doesn’t show.
9. SpyFu (Free / Limited Version)
For competitor insights, SpyFu is one of the better tools. While its full features are paid, you can use it for free searches.
How it works: Input a competitor domain or keyword, and you’ll get a glimpse of the keywords they are ranking for, ads they’ve run, and search history. Use this to find content gaps you can fill.

- Monitor and refine: Use Google Search Console and Bing Webmasters Tools (free) to monitor how your article performs. Use trend tools to revisit posts after a few months and update as needed.
Additional Tips For Trend & Topic Research
In addition to keywords, search trends and topic ideation are important for blogging success:
- Look for seasonal peaks using Google Trends — if you spot a topic climbing now, it may be smart to publish ahead of peak interest.
- Pay attention to **question keywords** — people often type “how to”, “why”, “what is” and other phrasing. AnswerThePublic helps you find these long‑tail angles.
- Use **cross‑platform keyword brainstorming** — e.g., YouTube and Amazon might surface topics that are trending for video/podcast content as well as blog posts. For example using YouTube Trend Finder tools you can spot video topics early.
- Use **Chrome extensions** like Keyword Surfer while browsing real search results to see related keywords and instant metrics. This helps you pick topics on the fly without leaving your browser.
- Keep a content idea list — whenever a tool shows a good keyword or trending topic, jot it down. Over time you’ll build a backlog of potential posts and avoid scrambling for ideas when it’s time to publish.
Common Mistakes When Using Free Keyword & Trend Tools
Even the best free tools won’t help if you misuse them. Here are mistakes to avoid:
- Choosing only high‑volume keywords — High volume often means high competition. Better pick moderate‑volume keywords you can realistically rank for.
- Ignoring user intent — “Keyword” is just a word. You must write content that satisfies what the user is actually searching for.
- Relying solely on trends — A topic may be rising, but if it’s extremely niche or temporary, you might not get much long-term traffic.
- Skipping content optimization — Keyword research is only half the job. You still need to write quality content, optimize on‑page elements and promote your article.
- Not updating content — Trends change; what’s hot today may fade. Refresh older posts so they stay relevant and maintain ranking.
