A successful SEO strategy starts with a strong foundation—and that means getting your on-page SEO right. Everything from how your page is titled to how content is structured affects how well your site performs in organic search.
Unfortunately, most website owners either skip audits or rely on generic checklists that miss critical, page-specific issues.
With AI, you can now audit your website’s on-page SEO automatically, intelligently, and at scale—without spreadsheets, manual scans, or technical SEO headaches.
In this guide, you’ll learn how to use:
- DIYSEO GPT to audit and analyze every key on-page SEO element
- The SEO AI Writer to fix and optimize weak content and structure
- The Link Marketplace to amplify optimized pages with external authority
Let’s break it down.
Why On-Page SEO Audits Matter
On-page SEO refers to everything on your site that influences rankings:
| Element | SEO Impact |
|---|---|
| Title tag | Impacts CTR and primary keyword targeting |
| Meta description | Drives user engagement and intent matching |
| Heading structure (H1–H3) | Organizes content and signals relevance |
| Keyword use | Ensures you’re targeting what users are searching |
| Internal links | Improves crawlability and session duration |
| Image alt text | Enhances accessibility and contextual SEO |
| Mobile readability | Affects bounce rate and user experience |
| Content depth | Helps match search intent and beat competitors |
If these elements are weak or misaligned, even great content won’t rank well.
Step-by-Step: How to Audit On-Page SEO with AI
✅ Step 1: Identify Audit Targets with DIYSEO GPT
Start by focusing on the pages that matter most for rankings, conversions, or visibility.
Run the following pre-built prompts inside DIYSEO GPT:
🔍 Top Performing Pages
Find which pages are driving the most traffic—and should be kept in top condition.
Ask:
“What are my top-performing pages by clicks and impressions, and are they fully optimized on-page?”
⚠️ Query Position Changes
See which pages are slipping in rankings due to on-page issues.
Ask:
“Which pages lost rankings in the past 30 days, and what can I fix on-page?”
📉 Crawled – Not Indexed
Uncover pages Google sees but refuses to index—often due to weak content or poor formatting.
Ask:
“What are the likely on-page issues preventing indexation for these URLs?”
✅ Step 2: Analyze On-Page Structure with Layout & Readability Review
This powerful DIYSEO GPT prompt reviews:
- Heading tag hierarchy (H1–H3)
- Paragraph density
- Keyword placement
- Mobile formatting
- Internal linking
Ask:
“Run a layout and structure audit on /ai-content-strategy. What can be improved?”
You’ll get a full breakdown of on-page weaknesses, including:
- Overused keywords
- Missing headers or subheadings
- Walls of text
- Weak or generic CTAs
- Pages with no internal links
✅ Step 3: Fix On-Page SEO Issues with SEO AI Writer
Once you have your audit insights, open the SEO AI Writer to rewrite and enhance problem areas quickly.
Prompt Examples:
Fix Weak Headers:
“Rewrite all H2s for this page targeting ‘AI-powered SEO tools.’ Make them engaging and semantically rich.”
Break Up Dense Content:
“Reformat this 400-word paragraph into 3 smaller paragraphs with bullet points and subheadings for mobile readability.”
Insert Missing Internal Links:
“Add a contextual internal link to /ai-seo-strategy using the anchor ‘automated SEO framework’ in this section.”
Add Schema-Ready FAQs:
“Write 3 FAQ questions and answers about ‘how AI helps with keyword research’ formatted for FAQ schema.”
Improve Metadata:
“Write a meta title under 60 characters and a meta description under 155 characters for the keyword ‘AI SEO audit tools.’ Include urgency and value.”
AI helps you improve SEO performance without rewriting your entire page manually.
✅ Step 4: Expand Content Where Needed
Many underperforming pages are simply too thin or shallow to rank competitively. Use your audit findings to identify where content needs to be expanded.
Prompt:
“Add a 300-word section about ‘automated backlink analysis tools’ to this blog post on AI SEO strategies.”
This not only improves keyword coverage but also supports Google’s content quality guidelines.
✅ Step 5: Monitor On-Page SEO Improvements Over Time
After you update and re-optimize your content, track results using DIYSEO GPT’s performance prompts.
Run:
- Top Queries by Clicks
- Query Position Changes
- High Impression, Low CTR
Ask:
“Has the updated /ai-seo-tools page improved in CTR, ranking, or click volume in the past 14 days?”
You’ll get actionable feedback to measure whether your changes are working—and what else to test.
Bonus: Promote Audited & Optimized Pages via Link Marketplace
Once your on-page elements are fixed and optimized, support those improvements with targeted backlinks from Link Marketplace.
Strategy:
- Choose your most important, newly optimized pages
- Filter Link Marketplace for publishers in your industry or niche (AI, SaaS, SEO, tech, etc.)
- Build 2–5 backlinks with keyword-optimized anchors that support the page topic
This external reinforcement complements your on-page fixes with authority, visibility, and faster reindexing.

Frequently Asked Questions
1. What is an on-page SEO audit, and why is it important?
On-page SEO audit is a comprehensive analysis of a website’s on-page elements—things you can control on your website to improve its rankings on search engines. This includes the content itself, images, URL structures, title tags, meta descriptions, and internal links. Performing an on-page SEO audit is crucial because search engines like Google use these elements to determine how relevant your website is to particular searches. By ensuring that your on-page SEO is optimized, you’re making it easier for search engines to understand your content, increasing your chances of ranking higher. An audit helps you pinpoint areas of improvement, keeps your content aligned with current SEO practices, and ultimately drives more organic traffic to your site.
2. How can AI assist in auditing a website’s on-page SEO?
AI can revolutionize the way you audit your website’s on-page SEO by making the process faster, more efficient, and more accurate. AI tools can thoroughly analyze a wide range of factors, providing insights into content quality, keyword usage, and overall SEO compatibility. These tools can help identify SEO opportunities you might miss manually, such as optimizing meta tags or restructuring URLs for better readability and emphasis. AI-driven insights aid in eliminating technical SEO issues such as broken links, duplicate content, or missing alt attributes for images. By leveraging AI, you can continuously monitor SEO performance, adapt to algorithm changes quickly, and keep enhancing your site’s on-page elements to maintain or improve search rankings.
3. What types of AI tools are available for conducting an on-page SEO audit?
Various AI tools cater specifically to SEO auditing. Tools like SEMrush, Ahrefs, and Moz offer comprehensive platforms that include AI algorithms to analyze on-page SEO factors. These platforms can provide keyword analysis, backlinks evaluations, and check content for SEO weaknesses. Similarly, specialized AI tools like SurferSEO focus primarily on content optimization, providing suggestions for improving keyword density, NLP optimization, and content relevance. Another tool, DeepCrawl, assists with technical SEO audits by exploring site structure, crawlability, and identifying potential roadblocks for search engine spiders. These tools, among others, incorporate AI technology to deliver actionable insights and tailored recommendations for improving your website’s on-page SEO.
4. Can AI tools completely replace manual SEO audit processes?
While AI tools provide immense value in streamlining and enhancing the SEO audit process, they cannot entirely replace the need for manual insight and expertise. AI is excellent at processing large amounts of data quickly, identifying technical issues, and offering improvement suggestions. However, it cannot fully replicate the strategic thinking, context, and intuition that an experienced human SEO analyst can provide. Human input is essential to integrate SEO with overall business goals, adjusting nuanced elements not strictly measurable by algorithms, and crafting content that appeals to human emotions and behaviors. Therefore, the best approach is to use AI tools as powerful enhancements to the manual SEO audit process rather than complete replacements.
5. What are some common on-page SEO issues AI can help identify?
AI tools excel at identifying a range of common on-page SEO issues that can impact your site’s performance. Some prevalent issues include keyword stuffing, which can lead to penalties, or insufficient keyword usage, which might prevent optimal ranking. AI can identify mismatches or inconsistencies in your title tags and meta descriptions, affecting click-through rates. Duplicate content issues, which can lead to indexing problems, are also swiftly uncovered by AI. Additionally, AI can detect missing or poorly structured internal links that could jeopardize your site’s ability to evenly distribute link equity across pages. It also identifies slow loading times which affect user experience and rankings, broken links that should be fixed or redirected, and missing alt text for images, impacting accessibility and search engine understanding. By addressing these issues, AI helps enhance your site’s SEO friendliness and search visibility.
