Common On-Page SEO Mistakes That Hurt Rankings
On-page SEO elements directly impact search engine rankings when implemented incorrectly. Our analysis shows these technical mistakes create barriers to achieving optimal search visibility.
Poor Title Tag Optimisation
Title tags serve as primary ranking signals for search engines. Missing or duplicate title tags reduce click-through rates by 25-35%. Here’s what makes title tags ineffective:
Using generic terms like “Home” or “Products” instead of descriptive keywords
Exceeding the 60-character limit which leads to truncated displays
Including irrelevant keywords that don’t match the page content
Copying identical title tags across multiple pages
Omitting the brand name from the title structure
Missing Meta Descriptions
Meta descriptions influence click-through rates from search results pages. Pages without meta descriptions see 35% lower engagement rates compared to optimised ones. Common meta description errors include:
Leaving meta description fields empty
Using automated descriptions that lack relevance
Creating descriptions longer than 155 characters
Writing duplicate descriptions for multiple pages
Failing to include primary keywords naturally

|---|---|
URL Parameters | -15% |
HTTP/HTTPS Versions | -25% |
WWW/Non-WWW Pages | -20% |
Product Descriptions | -30% |
Category Pages | -35% |
Publishing identical content across multiple URLs
Using manufacturer product descriptions without modifications
Creating similar category pages with minimal unique content
Syndicating content without canonical tags
Maintaining staging sites without proper access controls

Content-Related SEO Mistakes
Content mistakes in SEO directly impact website rankings and user engagement. Here are three critical errors that affect search performance and visibility.
Keyword Stuffing
Keyword stuffing creates unnatural content by forcing keywords into text repeatedly. Google’s algorithms detect this practice and apply penalties that reduce search rankings. For example:
Inserting the same keyword multiple times in meta descriptions
Adding irrelevant keywords in image alt texts
Repeating phrases unnaturally in content paragraphs
Using hidden text to place additional keywords
Thin or Low-Quality Content
Low-quality content fails to meet user expectations and search intent requirements. Common issues include:
Pages with fewer than 300 words
Content copied from other sources
Articles lacking specific details or examples
Posts without credible research or data
Blog entries that don’t address user questions
Missing Header Tags
Using one H1 tag per page for the main topic
Implementing H2-H6 tags to organise subtopics
Including target keywords in relevant headers
Creating logical content structure through proper tag hierarchy
Maintaining consistent header formatting across pages
Header Tag Level | Primary Purpose | Character Limit |
|---|---|---|
H1 | Main topic | 60 characters |
H2 | Major sections | 70 characters |
H3-H6 | Subsections | 80 characters |
Website Architecture Blunders
Website architecture forms the foundation of effective SEO performance. A poorly structured website architecture creates barriers for search engines to crawl pages efficiently reducing visibility in search results.
Poor URL Structure
URL structure affects both user experience and search engine rankings. Non-descriptive URLs like “website.com/page1” lack clear information about page content. Effective URLs include:
Relevant keywords that match page content
Short descriptive text separated by hyphens
Clear hierarchical structure reflecting site organisation
Consistent naming patterns across similar pages
Confusing Site Navigation
Clear navigation helps users and search engines understand website structure. Common navigation issues include:
Deep nested pages requiring 4+ clicks to access
Inconsistent menu structures across pages
Missing breadcrumb trails for hierarchy
Orphaned pages without internal links
Hidden pages excluded from main navigation
Incorrect XML Sitemap
Outdated page listings no longer on the site
Missing new or recently added pages
Incorrect page priority settings
Invalid sitemap formatting
Multiple conflicting sitemaps
Sitemap Element | Recommended Format |
|---|---|
Last modified date | YYYY-MM-DD |
Priority values | 0.0 to 1.0 |
Change frequency | daily/weekly/monthly |
File size limit | 50MB/50,000 URLs |
Link Building Mistakes
Link building forms a critical component of SEO strategy, yet many websites make fundamental errors in their approach. Our analysis reveals three primary link-building mistakes that damage search rankings.
Low-Quality Backlinks
Poor backlink profiles damage website authority through connections to spam sites, link farms or irrelevant domains. Google’s algorithms detect these low-quality links and apply ranking penalties. Here’s what constitutes low-quality backlinks:
Links from websites with no editorial standards
Connections to sites with malware or suspicious activity
Backlinks from domains unrelated to your industry
Links from sites with artificially inflated metrics
Ignoring Internal Linking
Internal linking creates pathways for both users and search engines to discover content effectively. Common internal linking errors include:
Missing links between related articles or product pages
Using generic anchor text like “click here” or “read more”
Creating orphaned pages with no internal links
Failing to link to important conversion pages
Breaking internal link structures during site updates
Over-Optimised Anchor Text
Anchor Text Type | Recommended % |
|---|---|
Brand/URL | 40-50% |
Generic | 20-30% |
Exact Match | 10-15% |
Partial Match | 15-20% |
Avoid repetitive keyword-rich anchors
Include branded terms in anchor text
Use descriptive phrases that flow naturally
Mix long-tail variations of target keywords
Balance commercial and informational anchor text

Frequently Asked Questions
What are the most common on-page SEO mistakes?
The most common on-page SEO mistakes include poor title tag optimisation, missing or poorly written meta descriptions, and duplicate content across pages. Title tags often exceed character limits or use generic terms, whilst meta descriptions fail to engage users effectively. These issues can significantly reduce click-through rates and harm search rankings.
How does page load speed affect SEO?
Page load speed is crucial for SEO performance. Sites that load in under three seconds retain more mobile visitors. Slow loading times, often caused by large image files, excessive JavaScript, and unoptimised CSS, can negatively impact rankings and user experience. Google considers page speed as a ranking factor, particularly for mobile searches.
Why is mobile responsiveness important for SEO?
Mobile responsiveness is critical due to Google’s mobile-first indexing. Websites must ensure proper text sizing, image scaling, and overall mobile usability. Poor mobile optimisation can lead to lower rankings, as Google primarily uses the mobile version of content for ranking and indexing websites.
What is keyword stuffing and why should it be avoided?
Keyword stuffing is the practice of unnaturally forcing keywords into website content. This outdated SEO tactic can lead to Google penalties and poor user experience. Instead, focus on creating natural, high-quality content that incorporates keywords meaningfully and provides value to readers.
How important are header tags for SEO?
Header tags (H1-H6) are essential for structuring content and improving SEO. Each page should have one H1 tag, with subsequent headers (H2-H6) organising subtopics logically. Proper header implementation helps search engines understand content hierarchy and improves readability for users.
What makes a good XML sitemap?
A good XML sitemap includes accurate, up-to-date page listings with proper formatting. It should contain last modified dates, priority values, and change frequency information. Avoid common mistakes like outdated listings or missing new pages, as these can hinder search engine crawling efficiency.
How can poor website architecture affect SEO?
Poor website architecture can make it difficult for search engines to crawl and index pages effectively. Issues include confusing navigation, non-descriptive URLs, and deep nested pages. A well-structured website with clear navigation and logical URL hierarchy improves both SEO performance and user experience.
What are the dangers of low-quality backlinks?
Low-quality backlinks from spam sites or irrelevant domains can harm your website’s authority and lead to Google penalties. It’s crucial to focus on acquiring high-quality, relevant backlinks from reputable sources while regularly monitoring and disavowing toxic links.
