On-Page SEO Checker
Compare your page against the top-ranking competitors for your target keyword. Get specific, actionable recommendations to improve your on-page SEO and outrank the competition.
What is on-page SEO?
The optimizations you control directly on your website to help search engines understand and rank your content.
On-page SEO refers to everything you can optimize on a web page itself to improve its search engine rankings. This includes the content visitors read, the HTML source code that search engines crawl, and the technical elements that affect how the page loads and renders.
Unlike off-page SEO (backlinks, brand mentions) or technical SEO (site architecture, crawl budget), on-page SEO is entirely within your control. It is the foundation that the rest of your SEO strategy builds on. A page with poor on-page fundamentals will struggle to rank regardless of how many backlinks point to it.
Our on-page SEO checker goes beyond generic checklists by benchmarking your page against the actual pages ranking in the top positions for your target keyword. This competitive comparison reveals the specific gaps between your page and the pages Google currently rewards.

On-page SEO best practices
Factor-by-factor guidance on what works, what to avoid, and what our tool checks.
Title Tags
Your title tag is the single most influential on-page ranking element. It appears as the clickable headline in search results and tells Google what the page is about. Keep it between 50-60 characters (or under 580 pixels) to avoid truncation.
Do
- Place your primary keyword near the beginning of the title
- Write unique titles for every page on your site
- Include a compelling reason to click, such as a value proposition or number
- Keep within 50-60 characters to prevent truncation
Don't
- ×Stuff multiple keywords into a single title tag
- ×Use generic titles like "Home" or "Welcome"
- ×Duplicate title tags across different pages
- ×Exceed 60 characters. Google will rewrite or truncate it
Meta Descriptions
Meta descriptions do not directly affect rankings, but they heavily influence click-through rate, which does. A well-written meta description is your pitch to the searcher. Aim for 120-160 characters (under 920 pixels on desktop).
Do
- Include the target keyword naturally. Google bolds matching terms
- Write a clear call to action or value statement
- Make it specific to the page content, not a generic company blurb
- Stay within 120-160 characters for full display
Don't
- ×Leave it blank. Google will auto-generate one, often poorly
- ×Copy the same meta description across multiple pages
- ×Stuff keywords unnaturally
- ×Make promises the page content does not deliver on
Heading Structure (H1-H6)
Headings create the content hierarchy that both users and search engines rely on. Use exactly one H1 per page (your main title). Use H2s for primary sections and H3s for subsections. Do not skip levels. H2 should be followed by H3, not H4.
Do
- Use exactly one H1 tag that includes your primary keyword
- Structure content with a logical H2 → H3 → H4 hierarchy
- Use headings to break content into scannable sections
- Include relevant keywords and variations in H2/H3 tags
Don't
- ×Use multiple H1 tags on a single page
- ×Skip heading levels (H2 straight to H4)
- ×Use headings purely for visual styling. Use CSS instead
- ×Write vague headings like "More Information" or "Details"
Content Quality & Depth
Content is what you are ultimately ranking. Google evaluates whether your content satisfies the searcher's intent better than competing pages. There is no magic word count. The right length is whatever thoroughly covers the topic. Our tool shows you how your content depth compares to the pages currently ranking.
Do
- Cover the topic as comprehensively as the top-ranking pages
- Use your primary keyword in the first 100 words naturally
- Include semantically related terms and synonyms throughout
- Answer the questions searchers are actually asking (check "People Also Ask")
Don't
- ×Write thin content when competitors publish comprehensive guides
- ×Repeat the same keyword unnaturally. Keyword density is not a real metric
- ×Pad content with filler to hit an arbitrary word count
- ×Ignore user intent. A transactional query needs a product page, not a blog post
Internal Links
Internal links distribute ranking authority across your site, help search engines discover and understand page relationships, and guide users to related content. Pages with more internal links pointing to them tend to rank higher. It is one of the most underused on-page SEO levers.
Do
- Link to relevant pages using descriptive anchor text
- Ensure important pages receive multiple internal links
- Link from high-authority pages to pages you want to rank
- Add contextual links within body content, not just navigation
Don't
- ×Use "click here" or "read more" as anchor text
- ×Link to the same page with the same anchor text dozens of times
- ×Leave important pages orphaned with no internal links pointing to them
- ×Overload a single page with 100+ internal links
Images & Media
Images improve user engagement and provide additional ranking opportunities through image search. But unoptimized images are one of the most common causes of slow page load times, which hurts both rankings and user experience.
Do
- Write descriptive alt text that includes relevant keywords naturally
- Use descriptive file names (seo-audit-checklist.webp, not IMG_4521.jpg)
- Compress images and use modern formats (WebP, AVIF)
- Specify width and height attributes to prevent layout shift
Don't
- ×Leave alt text empty on informational images
- ×Upload uncompressed images. A 5MB hero image destroys page speed
- ×Use the same alt text for every image on the page
- ×Rely only on decorative stock photos with no informational value
URL Structure
Clean, descriptive URLs help users and search engines understand what a page is about before visiting it. While URL structure is a minor ranking factor, good URLs improve click-through rates and are easier to share.
Do
- Include your primary keyword in the URL slug
- Use hyphens to separate words
- Keep URLs short and readable
- Use HTTPS across your entire site
Don't
- ×Use auto-generated URLs with IDs or random strings
- ×Include unnecessary parameters or session IDs
- ×Use underscores instead of hyphens
- ×Create deeply nested URL paths (/blog/2026/05/29/category/post-name)
Why competitor benchmarking beats generic checklists
Most on-page SEO tools run your page through a fixed checklist: Is the title under 60 characters? Does the H1 contain the keyword? Is the meta description present? These checks are useful but miss the point. Ranking is relative, not absolute.
A 1,500-word article might be too thin for a keyword where the top results average 4,000 words, or it might be more than enough for a keyword where concise answers dominate. A title tag might technically follow best practices but completely miss the angle that searchers prefer for that specific query.
Our on-page SEO checker solves this by comparing your page directly against the pages currently ranking in the top positions for your target keyword. Instead of generic advice, you see exactly where you fall short and where you already outperform the competition. The recommendations are calibrated to your specific keyword and competitive landscape.
