Best On-Page SEO Tools For Higher Rankings


Audiit is a one-stop-shop for all your on-page and technical SEO needs.

It makes site auditing easy and fun.

After using Audiit, technical on-page SEO won’t be boring for you anymore.

The tool only gives you the SEO information you need to push your site’s rankings upwards.

These include content length, keyword density, and just 8 more!

The best thing is it comes with a lifetime deal.

So, you don’t have to worry about paying a subscription anymore.

However, probably the only tiny drawback is that you can’t upload your own logo for now.

But, the feature is likely in the pipeline.


  • Super simple and effective
  • Very cost-effective
  • Lifetime deal
  • Powerful competitor analysis
  • Private Facebook Community


  • US, UK, and AU search results (for now)


SurferSEO is one of the best on-page SEO tools for beginners.

Here’s how it works:

  • You input a keyword or topic
  • It gives you suggestions in real-time
  • You make the edits

Basically, it helps you improve your on-page SEO by analyzing the first-page results for your target query.

The tool analyzes these pages for:

  • The average wordcount
  • The number of images
  • Paragraphs
  • Headings

To make the process easier for you, it gives your content a score out of 100.

The closer it is to 100, the better.

What’s more, its dashboard is user-friendly and easy on the eyes.

You can use SurferSEO to optimize your published content and boost your rankings or create blog posts from scratch.

However, not all keyword suggestions are relevant.

You have to select and deselect manually to optimize the keyword cluster.


  • Super easy to use
  • Smart SERP analysis
  • Highly effective
  • Content audits


  • Keyword suggestions aren't always on point
  • The price is a bit steep


Ahrefs is one of the most comprehensive SEO tools out there.

Its Site Audit tool tells you everything you need to know to fix your on-page SEO issues, including:

  • Performance: Site speed
  • Content quality: Duplicate pages, low word count
  • Problems with images, CSS, and JavaScript
  • Issues with HTML tags
  • And more!

What’s more, you can track your content’s search engine performance by using its Rank Tracker feature.

This gives you an opportunity to identify what’s working and move in the right direction.

However, although it’s an incredibly powerful on-page SEO tool, you can’t give it a try for free.

There’s no free trial, so you’d have to invest in it right off the bat.

And, it’s not known as the most budget-friendly tool in the SEO community either.


  • Powerful on-page SEO features
  • Very user-friendly
  • Reliable data
  • A huge online community


  • No free trial
  • A bit expensive


SEMrush is right up there with Ahrefs as far as popularity is concerned.

It equips you with every SEO feature you need to take your blog or website to the next level.

Its on-page SEO features include:

  • On-page SEO checker
  • SEO audit
  • Log file analyzer
  • Content optimizer
  • Rank tracking
  • And, more

Its SEO audit tool gives you actionable tips on how to improve your site’s technical on-page issues.

Whereas the on-page SEO checker tells you how to improve your content to win higher Google SERP rankings.

Moreover, the rank tracker lets you track your organic rankings and focus on the keywords that are working.

However, the SEO toolkit might be a little pricey.

But, if you have the budget, it’d be worth your buck.

All in all, if you’re after an effective technical and on-page SEO tool, SEMrush won’t disappoint you.


  • Comprehensive on-page SEO analysis
  • Phone, email, and chat support
  • Fairly easy interface
  • Offer reliable data


  • One of the more pricey ones on the market
  • Plans come with a single user account; additional seats cost extra


Frase is an AI-based software that has been helping content marketers with:

  • AI content generation
  • SEO optimization

As soon as you input your topic, it generates a detailed content brief for you.

Plus, its content score helps writers produce content that Google loves.

The “Content brief” feature of the tool really stands out for two reasons:

  • It saves your time
  • You get actionable tips for on-page optimization

It includes:

  • Overview
  • People Also Ask section
  • Topic clusters
  • Questions
  • Headers
  • External links
  • Statistics
  • SERP

Amazing, right?

The nice thing is you’ll have a lot of tutorials on how to effectively use this on-page SEO tool.

What’s more, Frase offers an easy-to-use interface.

And, you get unlimited documents on the team plan. A perk you won’t find in most of its competitors.

That being said, there are a few minor drawbacks as it’s relatively new.

For instance, the AI assistant isn’t the best, and the auto-save feature is a little flaky.

Plus, although there’s no shortage of tutorials, you might find it a little tough to use initially.


  • Super efficient
  • Research-based content briefs
  • Generate AI content
  • Unlimited documents (Except for the basic plan)
  • Comprehensive tutorials


  • Imperfect auto-save feature


ClearScope is a content optimization tool featuring:

  • Topic research
  • Content briefs
  • Content optimization

Essentially, it helps you optimize your web content or blog posts for better organic rankings.

What’s more, the SEO tool also generates AI content for you.

You can use it to generate blog copy, emails, web content, and more.

A stand-out feature of ClearScope is that it gives you secondary keywords for your main title.

This helps you rank your content for multiple keywords and drive more traffic to your website.

But, that’s not it. It also tells you:

  • The ideal length of your blog post
  • The readability score
  • How many times should you include target keywords

And, there’s something incredible:

If you don’t know how to use a particular keyword in your content, you can click on it and the tool will show you how your competitor has used it.

Plus, its user interface is simple and easy to use.

What’s more, the folks behind ClearScope have been great at improving the tool.

So, even if you see something lacking, chances are it’ll get that feature soon.

However, the cost can be a little too high for some, especially if you’re a solopreneur.

But, all in all, it provides great value and can help you produce high-quality, SEO-friendly content


  • Topic research
  • Easy to use and simple User interface
  • Powerful on-page optimization features


  • Pricey

Yoast SEO

If you have a WordPress blog or website, you probably have heard about YOAST SEO.

It’s a WordPress plugin that helps you optimize your web pages for search engines.

Not only that, but its real-time suggestions let you optimize your content for readers as well.

Here are the YOAST SEO features you need to know:

  • Internal and external linking suggestions
  • Readability analysis
  • Keyword density analysis
  • Meta description
  • Prior keyword usage (You don’t want to compete with yourself)
  • And more!

YOAST SEO is one of the best on-page SEO WordPress plugins, if not the best one.

The good thing is the free version is more than enough for on-page optimization.

You can always upgrade to a paid plan depending on your need and budget.

It’s also pretty user-friendly, so you’ll be able to use it effectively almost instantly.

However, YOAST SEO’s readability score isn’t always helpful.

For instance, it’d tell you to add more transition words to your content, even if they don't sound natural, which can be annoying sometimes.

But, that’s understandable as it gives suggestions based on AI.

All in all, YOAST SEO is a terrific on-page SEO tool that saves your time and helps you rank your content higher.


  • Easy to use
  • On-page content optimization for users and search engines
  • The basic free version is sufficient
  • Keyword analysis
  • Content score


  • Needs updating constantly
  • Might not be compatible with all plugins

Rank Math SEO

Rank Math is probably the biggest rival of YOAST SEO.

It’s a go-to on-page SEO tool for a lot of pro SEOs around the world, and for good reasons.

The WordPress plugin packs tons of powerful SEO features, including:

  • Simple and clean user-interface
  • Content AI
  • Advanced SEO analytics
  • Google indexing status
  • Rank tracker
  • Position tracking
  • Schema generator
  • And much more

Similar to YOAST SEO, Rank Math gives you real-time suggestions on how you can improve your content for SEO.

The nice thing is its free version is more than enough for on-page optimization.

However, probably the only drawback of Rank Math is that it’s a relatively more advanced tool.

This makes it ideal for more experienced SEOs and webmasters.


  • Simple, user-friendly interface
  • The free version is enough
  • Real-time content suggestions
  • The content score makes optimization easier
  • Content AI


  • Steep learning curve
