If you’ve ever written a blog or built a webpage and asked yourself,

“Is this good enough for Google?”
You’re not alone.

Creating content is hard enough. But making sure it’s optimized for search? That’s a whole other challenge.

The good news?
You don’t need expensive tools or a subscription just to write SEO-friendly content. In fact, some of the best tools out there are completely free, and they can help you make better decisions, from keyword planning to title writing to checking readability.

So, if you’re looking for free SEO tools for content optimization, this blog is for you.

Here’s a list of tools we at 360 Marketing Hub regularly use (and recommend), especially when working with small businesses, startups, or anyone trying to get more visibility, without spending more money.

1. Google Keyword Planner

Let’s start with the basics.

Before you write anything, you need to know what people are actually searching for. That’s where this free tool from Google helps.

You can enter a topic or idea, and it will show you:

• The search volume
  
• How competitive the keyword is
  
• Related keyword suggestions
  

It’s simple, free (you just need a Google Ads account), and it helps you plan your content around real search behaviour.

Best for: Keyword research before writing any blog, landing page, or website content.

2. Ubersuggest (Free Version)

Neil Patel’s Ubersuggest gives you solid keyword suggestions, content ideas, and even a basic SEO audit—all without paying for the premium plan.

Features include:

• Keyword difficulty scores
  
• Top-ranking content for your keyword
  
• Suggestions for what topics to cover
  
• Basic backlink data
  

You get 3 free searches per day (more if you’re logged in). It’s great for getting a quick overview of a topic.

Best for: Beginners who want a clean interface and helpful data without the overwhelm.

3. AnswerThePublic

This one’s a gem for content ideas.

You type in a keyword or topic, and it gives you a visual map of:

• What questions are people asking
  
• What comparisons they’re making
  
• What prepositions they use (e.g., “for,” “with,” “to”)
  

It’s great for writing blogs that answer real queries—exactly what Google wants.

Best for: Coming up with blog titles, FAQs, and “how to” content that actually gets searched.

4. Google Trends

Trends matter, especially if you’re writing around seasonal topics, news, or local events.

Google Trends helps you see:

• How interest in a topic changes over time
  
• What’s trending right now
  
• Regional differences in search interest
  

It doesn’t give you keyword volumes, but it tells you whether interest in a topic is growing, steady, or fading.

Best for: Picking topics that are timely, relevant, and likely to gain traction.

5. Yoast Real-Time Content Analyzer (Free Tool, No Plugin Needed)

Not everyone uses WordPress, but this tool works in your browser.

Paste your content, and Yoast will tell you:

• If your sentences are too long
  
• Whether you’re using enough transition words
  
• If your content is readable
  
• If your focus keyword appears enough times
  

It’s a great quick check before you hit publish.

Best for: Readability and basic on-page optimization without needing a plugin.

6. Hemingway Editor

This isn’t technically an “SEO tool,” but it’s a powerful content optimization assistant.

The Hemingway app checks:

• Sentence structure
  
• Passive voice
  
• Readability grade level
  
• Hard-to-read phrases
  

Why does this matter for SEO?
Because Google likes clear, concise content. And your readers do too.

Best for: Simplifying your writing so it’s more reader (and Google) friendly.

7. Google Search Console

Once your content is live, how do you know if it’s working?

That’s where Google Search Console comes in. It shows you:

• Which keywords are people using to find your site
  
• How many clicks and impressions are you getting
  
• Which pages are performing best
  
• What issues (if any) are stopping your content from ranking higher
  

It’s like having a direct line into what Google sees when it looks at your website.

Best for: Post-publishing performance tracking and spotting content gaps.

8. Grammarly (Free Version)

Grammar errors may not seem like a big deal, but they can affect your content’s trust factor—and even its readability score.

Grammarly helps you:

• Spot spelling and punctuation issues
  
• Keep your tone consistent
  
• Avoid awkward phrasing
  

The free version is more than enough for most content creators.

🛠 Best for: Clean, error-free writing—especially if you’re not a native English speaker.

9. SEOquake Chrome Extension

Want a quick SEO overview of any page, including your own?

SEOquake shows you:

• Page titles, meta descriptions, H1-H6 tags
  
• Keyword density
  
• Internal/external link count
  
• Mobile compatibility info
  

It’s not fancy, but it’s practical—and it lives in your browser.

Best for: On-the-go content audits, competitive checks, and quick improvements.

10. Notion or Google Docs + Checklist

This one isn’t a “tool” per se—but it’s what brings all the tools together.

At 360 Marketing Hub, we often build a simple checklist in Notion or Google Docs:

• ✅ Focus keyword in title
  
• ✅ Keyword in first 100 words
  
• ✅ Internal links added
  
• ✅ One H1, multiple H2s
  
• ✅ Alt text for images
  
• ✅ Clear CTA at the end
  

Before we publish anything, this checklist keeps us grounded. You can do the same—just copy it into your workflow.

🛠 Best for: Staying consistent with your SEO while keeping your content process simple.

How to Use These Tools Together

You don’t need to use all 10 tools for every blog. Here’s a sample flow you can follow:

1. Use Google Keyword Planner or Ubersuggest to choose your main keyword
   
2. Head to AnswerThePublic for content angles and question-based topics
   
3. Use Google Trends to check if your topic has search interest
   
4. Write your content in Google Docs, then paste it into Hemingway Editor
   
5. Use Yoast Analyzer or Grammarly for last-minute polish
   
6. Before publishing, run a quick audit with SEOquake
   
7. After publishing, track your performance in Google Search Console
   

All without spending a single rupee.
