Top 10 On-Page SEO Tools

With the rapid development of search engines, generating organic website traffic has become a considerable challenge. Simply publishing content and hoping for the best will not help you rank high in SERPs anymore. But what should you do to gain the highest possible organic search traffic? Which factors should you consider in the first place?

Once you build your website, you will need to make it clear to search engines what the theme and intent of your site is. This is where on-page SEO analysis comes into play.

On-page SEO, also known as on-site optimization, is the practice of improving both the site content (including text, media, and meta tags) as well as the HTML code and internal link structure. It refers to the optimization of all website elements that are within your control.

When done properly, on-page SEO becomes a truly effective tool for boosting rankings which will, in turn, result in more targeted visitors who will eventually be converted into leads and sales.

In this article, we’re going to take a good hard look at 7 of the best on-page SEO tools for enhancing your site’s performance. To make sure the results we get out of this comparison remain unbiased, we will analyze these tools using a combination of different metrics, including:

  • Page quality score
  • The number of competitors that can be analyzed
  • Range of issues explored
  • Recommendations on how to fix detected issues

Which On-Page SEO Tool Is Right for You?

By analyzing the comparison table outlined below, you’ll learn more about each tool’s on-page SEO capabilities and its functionality.

Consider asking yourself the following questions before deciding on which tool to use:

  • What features matter to my business the most?

Really ponder on these questions and take them seriously. Choosing the right on-page SEO tool will be much easier once you have a clearer picture in your head of the direction you want to take your site.

Top 10 Tools for On-Page SEO Analysis

Let’s begin by taking a step-by-step analysis of each tool, observing their strengths and weaknesses.

1. SE Ranking

se ranking

SE Ranking is an all-in-one SEO platform that offers a ton of strategic insights at your fingertips. Aside from analyzing a website’s health, keyword performance, and traffic, this tool can check the quality of your backlinks, provide audits for technical errors, do competitive research, and give recommendations for on-page and off-page SEO.

The On-Page SEO Checker offered by this service measures every page against 94 parameters, starting from the page’s title, content length, and keyword density all the way to the page’s usability and backlink profile. If at least one SEO parameter goes beyond the normal range, the tool immediately qualifies it as an error, warning, or notice. This distribution depends primarily on the impact that a specific element has on the page’s ability to get high positions on SERPs.

Every problem that SE Ranking finds comes with recommendations on how to fix it, so you won’t be required to research lots of information to figure out how to deal with the detected issue. The tool also provides a to-do list of tasks that should be completed based on the drawbacks found.

What’s more, unlike many other services that give recommendations based on standardized SEO guidelines, SE Ranking’s On-Page SEO Checker suggests improvements based on the actual metrics of the page’s direct competitors. For example, if your industry traffic is mostly mobile, you will be advised to keep your title tags under 60 characters despite the outdated recommendation that the title tag should fall within the range of 70 symbols.


  • Accurate page quality score based on nearly 70 parameters, with a different weight attributed to each indicator
  • Niche-specific SEO recommendations
  • The opportunity to get detailed insights on 3 to 50 SERP rivals
  • Recommendations are split between primary and secondary content


  • It can take some time to complete the loading/refreshing of some data 
  • Navigation might be a little confusing for new users


SE Ranking offers a 14-day free trial, after which you will need to subscribe to one of the following plans: 

  • Essential: $55 per month (up to 20 pages of one or different websites can go through on-page SEO analysis per month)
  • Pro: $109 per month (up to 30 pages of one or different websites can go through on-page SEO analysis per month)
  • Business: $239 per month (up to 100 pages of one or different websites can go through on-page SEO analysis per month)

You can save up to 60% off of the monthly price by regulating the frequency of rankings checks and by choosing the subscription period that best serves your needs and budget.


SE Ranking is a perfect fit for everyone interested in optimizing web pages to improve their rankings and user experience. Its On-Page SEO Checker offers an array of flexible and tailored features making on-site optimization as simple as possible. In addition to the high-quality on-page SEO process, SE Ranking is known across the board for providing accurate analyses of keyword rankings, scoping your competitors’ website traffic dynamics, and analyzing backlink profiles.

4. Woorank

It would be fair to say that—with over 10 years of experience in SEO—Woorank is one of the top competitors in this industry. By integrating Google Search Console, Google Analytics, and your Facebook page with this tool, you’ll be able to receive the most comprehensive information about your website performance to stay ahead of the competition.

Woorank doesn’t have a separate tool analyzing on-page SEO elements, but its Website Review feature performs complete SEO analysis from the perspective of both on-page and off-page optimization. In the on-page optimization block, you’ll have the opportunity to get information on content, indexing, mobile friendliness, structured data, security, domain, branding, and so on.

Screenshot of Woorank Page Review

Just plop your domain name or URL in the search box and review the list of suggestions divided into three groups: errors, to improve, and passed. The most critical problems will be highlighted in red, problems of less importance in yellow, and the pages that passed will be highlighted in green. Each suggestion comes with a tip on how to fix it, so you can save a lot of time and effort on seeking methods to address a certain issue.


  • Easy to navigate and work with
  • Free browser extension for on-page SEO
  • Accurate website SEO health score 


  • Each website can be compared to no more than 3 competitors
  • Not suitable for in-depth and complicated SEO problems


Each new customer is offered a 14-day free trial. Once it is over, you’ll be able to purchase one of the following subscription plans: 

  • Pro: $79.99 per month (analyze up to 2,500 pages)
  • Premium: $199.99 per month (analyze up to 10,000 pages)
  • Enterprise (contact the Sales Team to get to know more about this plan’s features and price)

Woorank can bring positive on-page results to freelancers and small business owners, as well as large companies that want to keep track of their online visibility. Still, it is not as advanced as the SEO tools that took top positions in our review. More advanced tools might be a better option if you’re looking for an in-depth analysis of your website’s nuts and bolts.

5. Sitechecker

Even though Sitechecker was founded less than 6 years ago, it has quickly risen through the ranks since 2016. Today, it is an all-in-one website monitoring tool for SEO, which has around 250,000 monthly users. Its main features include site audit, rank tracker, site monitoring, backlink tracker, and a Chrome extension for on-page SEO.

With the help of the on-page SEO plugin, you can check websites for more than 50 parameters related to the content, targeting words, links, images, meta tags, and webpage loading times. In turn, to get a prioritized to-do list with recommendations on how to fix the errors, you will need to insert your page’s URL into the On-Page Checker’s search box.

Screenshot of Sitechecker On-Page Checker

This is where you can get a general overview of your page’s components, such as content, URL, internal links, CSS files, mobile page speed, JavaScript files, and so on. By clicking on any detected issue, you’ll be able to get more details on how to correct it. Finally, if you want to send the whole on-page SEO report to a freelancer, an agency, or a colleague, simply copy a link to a report or download it in PDF format.


  • Its browser extension makes it possible to check the main aspects of your site’s on-page SEO 
  • Division of page-level issues into criticals and warnings, depending on their importance for on-site optimization
  • Website health score based on your site’s total number of errors and warnings


  • Lacking opportunity to compare side-by-side on-page parameters of a certain page with its rivals’ pages
  • Non-expert users may find it difficult to solve found problems, as some “how to fix” explanations are too complicated


The platform offers a 7-day free trial to all new customers. After the trial is over, you will need to select one of the subscription plans outlined below:

  • Basic: $29 per month (1,500 pages can be analyzed)
  • Startup: $49 per month (5,000 pages can be analyzed)

6. SEO PowerSuite

By using this offline platform, you can cover every step of your SEO campaign, from rank tracking and finding new backlink opportunities to providing in-depth on-page SEO analysis. You can serve these functions with the help of 4 powerful tools: SEO Spyglass, LinkAssistant, Website Auditor, and Rank Tracker. The Website Auditor should be your top priority when performing site audits and on-page SEO analysis. 

After launching the tool, run an on-site SEO audit by going to Site Structure -> Site Audit. Then, submit the required information to see the division of all detected problems from the analyzed website by: 

  • Errors: issues that need to be fixed immediately 
  • Warnings: less critical issues 
  • Info pages: the pages you’ll need to revise later.

If you want to analyze a specific page for its on-page SEO, head to Page Audit -> Content Audit. In this section, you can assess the quality of your on-site optimization through the webpage health score and receive tips on how to address problems related to HTML code, broken links, content, etc.

Screenshot of SEO PowerSuite Page Audit


  • All issues are divided into groups based on their prioritization
  • Each detected issue features a brief description and actionable recommendations 
  • WebSite Auditor tool is equipped with an in-built Content Editor ​​that assists with creating SEO-friendly content


  • Unlike cloud-based systems, this standalone desktop application can only be accessed offline
  • The loading speed depends on the type of computer you are using


Once the 7-day trial ends, you will need to make a choice between these subscription options:

  • Professional: $299 per year (unlimited number of pages can be audited)
  • Enterprise: $499 per year (unlimited number of pages can be audited)


Even though SEO PowerSuite is not a cloud-based system, and it requires a fast PC to function properly, this tool still deserves attention for its on-page SEO capabilities. With the help of its Page Audit feature, you can review your meta tags, spot images with empty alt text, fix broken links, and more. But take into account that SEO PowerSuite doesn’t offer a monthly subscription, so it would be wise to have long-term plans if you plan to use this platform.

7. Seobility

Screenshot of Seobility home page

Seobility is another useful online SEO software designed for website optimization, rank tracking, and backlink monitoring. You can use this application to check your entire website and even identify every page that contains errors.

The on-page SEO analysis is divided into 3 main categories: tech & meta parameters, structure, and content. By going through each section, you can find any errors affecting your SEO score as well as tips on how to solve them. Seobility can, for example, identify issues related to duplicate content, images without alt attributes, problematic domains, missing canonical links, long page response times, and so on.

Screenshot of Seobility Onpage SEO

What’s more, Seobility provides the opportunity to analyze all the issues within a single page. This means you can optimize the on-page elements of a specific page without having to dig into the audit of the whole website.


  • SEO audit is based on 300+ website factors 
  • Opportunity to set up automated and individually scheduled crawls
  • You can be notified via mail if the tool automatically identifies severe problems 


  • No opportunity to compare a specific page’s on-site optimization side-by-side with a competitor’s page
  • Outdated interface 


A 30-day free trial is only available for subscribers of the Premium plan.

  • Basic: free (this plan is not suitable for in-depth on-page SEO analysis, as many issues, such as duplicate content, pages with inappropriate titles, and competing pages with the same keyword optimization, cannot be identified with this subscription)
  • Premium: $50 per month (crawling of up to 25,000 subpages)
  • Agency: $200 per month (crawling of up to 100,000 subpages)

With the annual subscription, you can save up to 30% off of the total monthly price.


This platform can be an excellent choice for finding and solving in bulk both technical and on-page SEO issues that your website might have. Unfortunately, this tool doesn’t provide specific recommendations on how to improve on-page performance for specific pages. You will need to do your own research on best SEO practices to get a top position in SERPs.

8. SEO Tester Online

The service offers a very simple on-page SEO tool. Just enter the URL of your page and click the research button — you can test this functionality for free! You get not only an overall score on a 100-point scale but also a spider diagram that displays various aspects of optimization — mobile and desktop versions, technical base, content, and social media. 

Each report can be opened by accessing the corresponding on-page SEO tools. If you have a paid subscription, the service will also provide detailed information about errors, sorting them by their impact on website rankings and by the time they should be fixed.

  • The knowledge base could be more complete — there is a lack of description of some on-page SEO checker features
  • Some users complain about slow technical support
  • The reports lack details on keywords and backlinks


On-page SEO checker offers a very wide range of pricing plans

  • Personal Lite — $26, 1 project, keyword research, and audit only

  • Personal Plus — $56, 5 projects

This on-page SEO checker combines a wide range of features with a user-friendly interface. It allows you to identify all the weaknesses of your site and make a list of necessary work. Its advantages also include a flexible pricing policy — there are optimal subscription plans for freelancers and businesses of all scales. But the service can only be recommended if you already have the necessary knowledge — both technical support and training materials on the site could be much better. 

9. Moz Pro

On-page SEO checker is only one of the many functions in this service. But the developer devoted much attention to it. By specifying the URL of the page, you get not just a detailed report but complete instructions for further optimization of the site. The on-page SEO tool highlights errors and suggests the best ways to solve these problems. If they relate to program code, it can even provide examples of optimal tags and scripts to replace them!

Moz Pro’s on-page SEO tools allow you to set up regular site audits. You will receive the results in the web interface and via email. If necessary, you can send white-label reports to clients directly by customizing their structure. 

In addition to best on-page SEO checkers, Moz offers a number of unique products. Among them is a local optimization service that allows small businesses to get to know their local customers by establishing a close connection with their target audience. And large companies will appreciate a product called STAT — advanced analytics with the possibility of customizing reports and calculation methods. 


  • Along with SEO on-page tools, you get many other features, including keyword research and backlink analysis
  • A very deep knowledge base — the service teaches you how to optimize websites and various ways to promote your business online on your own
  • Quick site audit, convenient report with an intuitive arrangement of key elements
  • A large number of filters, the ability to quickly select the necessary indicators


  • Very complicated interface — if you need any functions other than an on-page SEO checker, you can spend a lot of time searching for them
  • Beginners will need prior training to use this service
  • Sometimes, there are technical errors that force you to run the analysis again


Unlike competing on-page SEO analysis tools, Moz Pro doesn’t limit the functionality of its subscription plans — they differ in request limits and the number of users. Currently, the following plans are available to you:

  • Standard — $99
  • Medium — $179
  • Large — $299
  • Premium — $599

The discount for paying a year in advance is 20%. The first two subscription plans can be tested for free for 30 days.

Moz Pro is an on-page SEO checker tool for professionals or those who want to reach a high level of competence. Beginners will have to get used to both its inconvenient structure and the staggering amount of data. But over time, they will be able to quickly find and correct errors, significantly improving their website rankings. 

10. SEO Site Checkup

If you’ve been looking for easy-to-use on-page SEO software, this is the option to choose. You don’t have to get confused by the list of features and spend hours getting used to the menu structure. Just enter the URL and click the start button — you will get all the necessary reports on the next screen. 

The service offers the same on-page SEO tools as competitors — testing the technical base, checking loading time, auditing content, etc. It is not limited to your website — the report also shows the state of your link network and a comparison with competitors. 

The most interesting thing is that almost every on-page SEO checker tool is available to you for free, but only if you run it separately. This allows you to thoroughly test all the features of the web service before subscribing. 


  • The simplest possible interface — suitable for beginners and small business owners
  • The ability to run SEO on-page SEO checker on a schedule — if it detects a new error, you will immediately receive a warning
  • Availability of white-label reports with individual content customization
  • High-quality technical support in all subscription plans


  • The on-page SEO checker service is inferior to its competitors in terms of report granularity
  • The results lack visualization — it is difficult to draw conclusions quickly when reading large amounts of text
  • The interface looks outdated — the service is not always convenient to use on a smartphone or tablet 


The on-page SEO tool offers the same simple subscription options as its reports. There are only three of them, and they differ in the number of requests:

  • Basic — $29.95
  • Webmaster — $49.95
  • Professional — $89.95

An annual subscription to the on-page SEO checker gives you a 10% discount. A 7-day trial period is also available to users.


This on-page SEO tool is one of the best for beginners who are just starting to learn SEO on their own. A simple report structure and a blog with a large number of articles allow you to quickly master the main categories and tools. The functionality will be quite adequate for freelancers and small businesses, but large companies may not find the reports they need.

To Wrap Up

The platforms presented in this article are exceedingly helpful in terms of on-page SEO because they provide the necessary tools to optimize your web page’s content and HTML source code. Any of these tools will undoubtedly make a huge contribution to your overall SEO campaign.

We do believe, however, that the SE Ranking tool is the cream of the crop because of its versatility and other combined strengths. These strengths include but are not limited to low price, niche-specific SEO recommendations, the opportunity to get complete insight on up to 50 SERP competitors, as well as clear prioritization of tasks that need to be done to optimize webpages. 

Alternatively, Semrush and Serpstat can also perfectly fit your SEO strategy for on-site optimization. Each of these tools offer advanced options for SEO health checks, page content optimization, and internal linking opportunities. 

Woorank, Sitechecker, SEO PowerSuite, and Seobility might be less popular in the SEO industry, but they can still improve both your webpage’s search engine optimization and user experience.

Ultimately, take some time to think about it before rushing to buy one of these tools. Get clear about your on-page SEO goals and expectations in advance so that way it will be easier for you to decide which of these tools will be the most appropriate and effective for your business.
