Guide To Some Of The Most Common Search Engine Optimisation / SEO Mistakes
SEO or search engine optimisation is key to getting your business noticed online, but it’s easy to stumble into common mistakes that can hurt your website’s performance. This guide to SEO mistakes highlights these pitfalls and offers practical solutions to avoid them.
For starters, what are errors in SEO?
Errors in SEO refer to mistakes or issues that can negatively affect the performance of a website in search engine rankings. These errors can prevent search engines from properly crawling, indexing, and understanding your content, which can hinder your website’s visibility in search results. Identifying and fixing SEO mistakes is crucial for maintaining a healthy website and ensuring it ranks well.
Why is it crucial to fix SEO mistakes right away?
Fixing SEO mistakes as soon as they are identified is crucial because errors can negatively impact your website’s rankings, visibility, and user experience. Issues such as broken links, slow load times, or incorrect redirects can result in poor search engine rankings and lost traffic. Addressing these mistakes promptly ensures that your site remains competitive, maintains a strong user experience, and optimizes performance, leading to better search engine results and higher conversion rates.
What are some of the most common SEO mistakes?
Here are some examples of common types of SEO mistakes and errors people make:
- 404 Errors (Page Not Found): This occurs when a page on your website is missing or deleted, and users or search engines encounter a “404” error when trying to access it. These broken links can harm your site’s user experience and SEO performance. Redirecting 404 pages to relevant pages or restoring the original content can help resolve this error.
- Duplicate Content: This error happens when the same or very similar content appears on multiple pages of your website or on different websites. Search engines may struggle to determine which version of the content to rank, and this can result in lower rankings for all affected pages. Using canonical tags and ensuring each page has unique content can help prevent this.
- Missing Meta Tags (Title & Description): Meta tags like titles and descriptions provide search engines with information about your content. If these tags are missing, duplicate, or poorly written, it can negatively impact your rankings and click-through rates (CTR). Ensuring each page has a unique, descriptive title and meta description is important for good SEO.
- Broken Internal Links: Internal links are links that point to other pages within your own website. If any of these links are broken (e.g., they lead to non-existent pages), it can create a poor user experience and negatively affect your site’s crawlability. Regularly checking and fixing broken internal links is vital for a healthy SEO structure.
- Slow Page Load Speed: If your website takes too long to load, it can lead to higher bounce rates and lower user satisfaction, which can negatively impact your SEO. Google and other search engines consider page speed as a ranking factor. Optimizing images, reducing the number of plugins, and leveraging caching can improve load times.
- Mobile Usability Issues: With mobile-first indexing becoming the norm, it’s essential that your website is fully optimized for mobile devices. Errors such as text that is too small to read, buttons that are hard to click, or pages that don’t load properly on mobile devices can harm your rankings. Ensuring your website is mobile-friendly is crucial for good SEO.
- Missing Alt Text for Images: Search engines can’t “see” images, so they rely on alt text to understand what each image is about. If your images lack descriptive alt text, you may be missing out on potential SEO benefits, especially for image search rankings. Always use relevant, descriptive alt text for your images.
- Incorrect Redirects (301/302): Redirects tell search engines and users when a page has been moved to a new location. Incorrect or improperly set up redirects can lead to SEO issues, such as loss of link equity or crawling issues. Using 301 redirects (permanent redirects) properly can preserve your SEO value.
- Thin Content: Thin content refers to pages with very little original or valuable information. Pages that are deemed low-quality or lack substance may be penalized by search engines. Creating comprehensive, well-researched content is key to preventing thin content errors.
- Poor URL Structure: URLs that are too long, contain unnecessary characters, or lack relevant keywords can hinder SEO performance. Simple, descriptive, and keyword-optimized URLs help search engines understand the content of your page and improve rankings.
Why Fixing SEO Errors Matters:
Addressing errors in SEO is essential to improving your website’s visibility, user experience, and overall performance in search engines. Fixing errors can lead to better crawlability, higher rankings, more organic traffic, and increased conversions. Regularly auditing your website and correcting errors is an ongoing process that contributes to long-term SEO success.
By identifying and resolving SEO mistakes, you ensure your website is fully optimized and prepared to perform well in search rankings.
Below we will discuss 17 of the more common mistakes in see SEO
1. Skipping keyword research
Why is keyword research so important? Jumping into content creation without thorough keyword research is a big SEO mistake. It can result in targeting the wrong keywords or missing out on the search terms your potential customers are using.
Example: Imagine you run a bakery and start writing blog posts about “baking techniques” without checking if people are actually searching for that term. You might miss out on more popular searches like “how to make sourdough bread” or “best gluten-free cookies recipe”.
Solution: Use tools like Google Keyword Planner, Ahrefs or Semrush to find the right keywords for your industry. Focus on long-tail keywords, as they are usually less competitive and more specific to your niche. Keep your keyword list updated to match market trends and user search behaviour.

2. Ignoring on-page SEO
Neglecting on-page SEO elements like title tags, meta descriptions and image alt text can reduce your content’s visibility on search engines.
Example: If your website’s pages have generic title tags like “Home” or “About Us”, search engines and users won’t know what specific information the page contains, leading to lower search rankings and fewer clicks.
Solution: Ensure every page on your site has unique, descriptive title tags and meta descriptions that include your main keywords. Use header tags (H1, H2, H3) to organise your content and naturally incorporate keywords. Add alt text to images to help search engines categorise your content better.
3. Creating low-quality content
Google’s growing focus on expertise, experience, authoritativeness and trustworthiness (E-E-A-T) highlights the need to create high quality content that showcases your credibility and authority in your industry. Producing content just to have something on your site, rather than offering value to your audience, can damage your SEO efforts.
Example: Writing a blog post filled with fluff and lacking real information just to hit a word count can turn readers away and increase your bounce rate, negatively impacting your SEO.
Solution: Focus on creating high-quality, informative and engaging content that meets your audience’s needs and interests. Analyse competitors to see what works well in your niche and aim to provide even better up-to-date information.
4. Neglecting mobile optimisation
With most users accessing websites via mobile devices, overlooking mobile is a big SEO mistake that can lead to a poor user experience and lower rankings on mobile searches.
Example: If your website is designed only for desktop users, it might look cluttered or be hard to navigate on a smartphone, causing visitors to leave quickly.
Solution: Implement a responsive design to ensure your website looks and functions well across devices. Use Google’s Mobile-Friendly Test tool to identify and fix any mobile usability issues. Optimise images and reduce file sizes to boost page load speed on mobile devices.
5. Ignoring technical SEO
Overlooking technical SEO aspects such as site speed optimisation, broken links and crawl errors can prevent search engines from properly indexing your site.
Example: A website with slow loading times, broken links or inaccessible pages can frustrate users and cause search engines to rank it lower.
Solution: Regularly audit your website using tools like Google Search Console, Screaming Frog or Ahrefs. Fix any broken links, optimise site speed by compressing images and leveraging browser caching for search engines to crawl and index.
6. Having poor internal linking structure
Failing to implement a strategic internal linking structure can hinder your site’s navigability and reduce the authority passed between pages.
Example: If your blog posts and pages are not linked to each other, visitors may have a hard time finding related content and search engines may not see the connection between your pages.
Solution: Create a better internal linking strategy by linking related content together. Use descriptive anchor text that includes relevant keywords.
7. Not using analytics
Without monitoring your SEO performance, you won’t know what’s working and what’s not, leading to missed opportunities for improvement.
Example: If you don’t track your website’s traffic or conversion rates, you might continue investing in ineffective SEO strategies.
Solution: Set up Google Analytics and Google Search Console to track your site’s performance. Monitor data such as organic traffic, bounce rate and conversion rate. Use this data to refine your SEO strategy and make informed decisions.
8. Keyword stuffing
Using too many keywords in web content leads to a poor user experience and penalties from search engines.
Example: A blog post that contains so many instances of the same keyword — and placed unnaturally throughout the text — can be hard to read and may be flagged as spam.
Solution: Focus on writing natural, readable content that is useful to your audience. Use keywords strategically and sparingly, ensuring they make sense in your text. Aim for a keyword density of around 1-2%.
9. Ignoring local SEO
Businesses with a physical presence should never neglect local SEO. Otherwise they will be missing out on valuable local search traffic.
Example: A local pizza restaurant that doesn’t optimise for local search terms might not appear in search results when people look for “best pizza near me”.
Solution: Optimise your Google My Business listing by ensuring your NAP (name, address, phone number) information is accurate and consistent. Encourage satisfied customers to leave positive reviews. Also, include local keywords in your content and meta tags.
10. Not building quality backlinks
Relying on low-quality or spammy backlinks can harm your site’s credibility and search engine rankings.
Example: Participating in link farms or buying cheap backlinks can reduce your site’s visibility.
Solution: Focus on building high-quality backlinks and creating a strong link profile from reputable sites within your industry. Guest blogging, influencer collaborations and content marketing are effective strategies for acquiring quality backlinks. Regularly check your backlink profile and get rid of harmful links.
11. Ignoring user experience (UX)
Poor user experience, such as difficult navigation, slow load times and intrusive pop-ups, can lead to high bounce rates and lower rankings.
Example: A website with a cluttered layout and slow-loading pages can frustrate visitors, causing them to leave quickly and harming your SEO.
Solution: Prioritise user experience by ensuring your site is easy to navigate, loads quickly and offers valuable content. Use tools like Google PageSpeed Insights to find and fix performance issues. Implement a clean, user-friendly design and avoid disruptive elements like excessive pop-ups.
12. Not using schema markup
Failing to use schema markup can result in missed opportunities for enhanced search engine results, such as featured snippets.
Example: Without schema markup, your product pages might not show additional information like ratings and prices in search results, missing out on potential clicks.
Solution: Implement schema markup on your site to help search engines understand your content better and provide enhanced results. Use Google’s Structured Data Markup Helper to add schema markup to your pages.
13. Posting or having duplicate content;
Having duplicate content on your site can confuse search engines and dilute your page authority.
Example: If your blog and product pages contain the same descriptions or articles, search engines might struggle to determine which version to prioritise.
Solution: Use tools like Copyscape to identify and eliminate duplicate content. Check that each page on your site has unique, high-quality content. If you need to have similar content, use canonical tags to indicate the preferred version to search engines.
14. Neglecting voice search optimisation
Ignoring the rising trend of voice search can result in missing out on potential traffic from users of voice assistants like Siri, Alexa or Google Assistant.
Example: If your content isn’t optimised for voice search, users asking “Where can I find the best pizza near me?” might not find your website in the search results.
Solution: Optimise your content for voice search by focusing on natural language and long-tail keywords. Answer FAQs in a conversational tone and use structured data to improve your chances of appearing in voice search results.
15. Not updating old content
Allowing your content to become outdated can negatively impact your site’s relevance and rankings.
Example: An old blog post with outdated statistics or information can turn visitors away and lower your search rankings.
Solution: Regularly update your content to ensure it remains accurate and relevant. Add new information and refresh statistics to improve the page’s relevance. Republishing updated content can also give it a fresh boost in search rankings.
16. Improper use of redirects
Using too many 302 or 301 redirects can slow down your website and lead to indexing issues with search engines.
Example: If your site has numerous outdated pages all redirecting to new ones, it can create a convoluted path for search engines and users, leading to slower load times and potential indexing issues.
Solution: Use redirects sparingly and appropriately. Use 301 redirects for permanent changes and 302 redirects for temporary ones. Check your redirects to ensure they’re functioning correctly.
17. Ignoring user intent
Creating content that doesn’t align with the user’s search intent can result in high bounce rates and low engagement.
Example: If you target a keyword like “best running shoes” but your content only lists different brands without detailed reviews or buying guides, users looking for comprehensive information might leave your site quickly.
Solution: Understand and address the different types of user intent. Informational intent seeks knowledge or information, navigational intent aims to find a specific website or page and transactional intent focuses on completing a purchase or action.
By addressing these additional common SEO pitfalls, you can further strengthen your website’s performance and improve your search engine rankings. Continuously monitor your SEO efforts and adapt your strategy to maintain a competitive edge.
