What is an on-page SEO checker?
An on-page SEO checker audits one page against the keyword you want it to rank for. It reads the page the way a search engine does and checks the URL, title and meta description, headings, content, images, internal and external links, page speed and HTTP requests, then gives the page a score out of 100 and a prioritised list of fixes.

Audit types and what each one checks: Run an SEO audit.
Know your page speed metrics
Improve your page loading time with the recommended targets from the report.
Fully loaded time
Find out how long the page takes to load completely. Keep it under 2 seconds; a slower page has a negative influence on your rankings.
Server blocking time
Know how long requests wait before they are sent. Keep it within the target (200 ms or less), or it hurts the overall page performance.
Server connection time
If the server takes too long to open a connection, the whole page slows down. The report target is under 50 ms.
Server response time
Server response time is often overlooked when optimising speed. A good server response time is 200 ms or less.
Time to First Byte (TTFB)
Look at the server side, where the page begins to load, and see what slows the first response. Aim for a TTFB of 200 ms or less.
HTTP requests
Count the HTTP requests your page makes. The more requests, the longer the page takes to load. Do not exceed 30 HTTP requests.
Page size
Page size affects both ranking and performance. Measure the size of your page and keep it to no more than 150 KB.
First Contentful Paint
Google recommends a First Contentful Paint of 1.8 seconds or less for a good user experience. Over 3 seconds is considered slow.
Check your HTTP requests
Find out how many HTTP requests your page generates in total, broken down by type.
Image requests
Every image adds an HTTP request, and more requests mean a slower page. See the image requests on your page and keep large images under 300 KB.
JavaScript requests
Get a summary of your JavaScript requests with the recommended limits. Minify and combine scripts; the total size of JavaScript requests should not exceed 150 KB.
HTML requests
Unnecessary code adds weight to every load. See the size of your HTML requests and the recommended limit.
CSS requests
Audit the CSS files requested on the page, with recommendations. Cleaning up unused CSS reduces requests and speeds up loading.
Error requests
Identify every request that returns an error, with a concise, actionable list. Error requests degrade the page, so there should be none.

On-page SEO checker FAQ
Got questions about our on-page SEO tools? Here are some answers.
What is on-page SEO? How many types of SEO are there?
On-page SEO is the practice of improving your site’s rankings and user experience by optimising individual pages in line with Google’s guidelines. It helps you earn relevant traffic from search engine results pages (SERPs) by optimising both the on-page elements and the HTML source code, so the page can rank for the keywords you target. On-page SEO analysis tools help you reach those goals.
For well-rounded organic results, you need three types of SEO: on-page SEO, technical SEO and off-page SEO. If you split your plan into these three areas, it is much easier to organise and implement.
Is on-page SEO still required for websites?
Yes. Many people focus on off-page SEO, but without fixing the issues on your landing pages you can’t reach your off-page goals. On-page SEO is much more than placing a keyword here and there.
Most websites are built with flaws, because web developers are rarely SEO experts. On-page SEO helps search engines understand your content and rank it for the most relevant queries, and user-focused on-page factors matter more as Google’s algorithm becomes more complex.
An on-page SEO audit is no longer complicated: an on-page SEO audit tool gives you a detailed report of the ranking factors you need to work on, so your website and content follow SEO best practice. A great user experience should be your first concern.
Why do I need on-page SEO?
On-page SEO helps search engines understand your website’s content. After keyword research and competitor analysis, an on-page SEO audit is the next step: its report shows what you need to do. Because on-page SEO has many parameters, a checklist makes sure nothing is missed.
Content analysis: high-quality content is the first and most important part of on-page SEO. Analyse your title tags, keywords and headings, and make sure the content answers specific search queries. Prioritising content quality improves rankings and conversion rates in the long run.
Proper use of keywords: on-page SEO makes sure the page is optimised for its keywords, so Google understands what it is about. It shows the most-used keywords on the page and where the keyword appears in the URL, title, images and headings, while keeping the wording natural.
Image optimisation: image names and alt tags should be in place and include the keyword where it fits.
Internal and external link analysis: links are an important and often overlooked ranking factor. The audit checks your internal and external links so they add authority and trust.
The Web Page Audit checks 179 on-page factors, shows whether your page is properly optimised and gives guidance for every SEO error.
What’s the difference between on-page and off-page SEO?
On-page and off-page SEO sit on opposite sides of the SEO spectrum, but they complement each other: you can’t succeed by focusing on only one. On-page SEO examines the content of your website or page, while off-page SEO examines its authority and popularity. In short, on-page SEO decides what you can rank for, and off-page SEO decides how high you rank.
Basic on-page SEO checklist:
- Website goal analysis
- Competitor analysis
- On-page SEO performance analysis
- HTTP request analysis
- The important on-page factors: URL, title tags, meta tags, headings, keywords, content, image alt tags, page speed, mobile friendliness, page experience, internal linking and external linking
Basic off-page SEO checklist:
- Backlink analysis
- Competitor backlinks
- Fixing 404 errors
- An off-page strategy: outreach, guest blogging, local citations, reviews and recommendations, and Google Business Profile analysis
You don’t have to choose between them: together they build a solid foundation. For the on-page side, an on-page SEO audit tool is easy to use and works well alongside your off-page strategy. To watch your links, see backlink monitoring.
How can I find out my page’s SEO score?
An SEO score measures how well a page meets search engine guidelines, based on its technical setup, content, user experience and mobile experience. It is graded out of 100: 75 or higher is Good, 55 to 74 is Needs work and under 55 is Poor.
You could calculate it by hand with a manual audit, but that risks mistakes. Most SEO professionals and agencies use an on-page SEO checker instead. Enter your page URL and target keyword in the form at the top of this page, and your score opens in seconds. Based on the score and the issues list, you can see what to do to improve it. See also the SEO score checker.
How do you conduct an on-page SEO audit?
You can audit a page manually or with SEO software. A manual audit takes a long time and is prone to errors; an SEO tool does it in seconds, and you don’t need several tools.
- Enter the page URL and the keyword you want to target in the form on this page, or start the 14-day free trial and click New audit in the app.
- The tool prepares your on-page SEO report, which lists all the on-page issues by priority.
- It covers every area you need to double-check: the on-page SEO score, page speed metrics, content readability, a breakdown of HTTP requests, on-page statistics, mobile usability, the URL, the title tag, the meta description, image analysis, the list of images, images from other sources, the heading tags, the most-used keywords and all internal and external links.
These issues can stop your site from being crawled and indexed properly, so fix them before they hold your website back.
What is an on-page SEO tool, and how does it work?
An on-page SEO tool runs a quick, high-level analysis of a page and shows what it needs to rank higher, with specific suggestions to increase search traffic. You get an on-page SEO report after the analysis, and you can make it white label: the report carries your company’s branding, and you can email the PDF to your clients right away.
SEO is hard to master, especially for beginners. The tool takes the time-consuming analysis off your hands, shows what is working and what to change, and explains how to fix each problem and where your biggest chances are. If you work on several client projects, you can check each website on the fly instead of copying data into a spreadsheet. You can try the on-page SEO checker free for 14 days.
Why do web developers need on-page SEO tools?
On-page SEO is not only an SEO expert’s job. A web developer has to deliver a site that looks good, works well and helps the client succeed online, and that includes SEO.
SEO may not be in your job description, but getting the key on-page metrics right makes you more valuable and gives clients the foundation to rank well. Run an audit to find the loading time, performance issues and other technical problems that get in the way, with clear, human-readable suggestions for each fix. It makes it easier for the developers on your team to build and maintain sites in line with Google’s guidelines.
What can I do to boost the on-page SEO performance of my page?
SEO helps a website reach the top of search results and generate business leads, which turn into revenue. It is an ongoing process: page speed, URL optimisation, meta tags, header tags, keyword placement, image optimisation and more. Alongside the on-page analysis, you can:
- Publish relevant, authoritative content. High-quality content is the number one driver of search results.
- Update your old content regularly.
- Add relevant links within the content to build authority and credibility. Instead of “click here”, write out the destination’s name or topic.
- Use alt text to describe your images and videos.
- Work on local SEO and off-page SEO.
- Monitor and update the page regularly with on-page SEO tools.
What happens if my on-page SEO score drops?
Scores and rankings can drop unexpectedly. To see what changed, track your keywords with the keyword rank tracker. To win back your score:
- Find out why it happened. Track your keyword rankings daily: Google’s algorithm changes, and rankings can drop suddenly.
- Check for a penalty. Review your link building, and use the on-page SEO tools to analyse your internal and external links, then resolve the issues.
- Keep your content up to date. If new content is not indexed despite having no technical issues, the topic may already be well covered by high-authority sites. Create unique, high-quality content that is relevant to your website and your users.
- Keep your title and meta information up to date. If Google rewrites your title or meta description, it no longer describes the page well. Write meta information that helps search engines understand what the page is about.
This is only the first step. Monitor and fix your on-page SEO issues with on-page SEO tools regularly to keep the site tidy.
Can I outrank my competitors if my on-page SEO score is bad?
Yes, you can still outrank competitors if you focus on your content and the keywords you want to rank for. Some simple ways:
- Publish high-quality content
- Optimise your URLs for link building
- Resolve navigation problems
- Fix images that are not optimised
- Replace missing or duplicate meta tags
- Make sure your website is mobile-friendly
Still, the SEO score is an important measure to work on, with the step-by-step fixes from the on-page SEO tools.
