AI came into our lives, and no human writers are needed now. If you tend to believe it, you make a huge mistake. AI-generated content usually means:
Error Correction: Use tools like Originality.AI, Copyleaks AI Content Detector or Grammarly Premium to evaluate the amount of AI generated text. From our experience, Grammarly Premium is the best one. Remember that for a proper ranking, your text must contain no more than 20% AI patterns.
Do you think content doesn’t matter? Think twice. Non-optimized content is a key reason why even high-quality materials fail to produce results.
Pages that Google’s algorithms will love should include:
- Meta-title and Meta-description;
- Main and additional keywords (high, low, and zero frequency);
- LSI Keywords.
Error Correction: Use Yoast SEO or Ahrefs to ensure that your content includes optimized meta tags, keywords, and proper LSI keywords that enhance visibility and rankings.
Content duplication across multiple pages of your website can lead to:
Always make sure that each page has unique and original content, and avoid copying content from other sources.
Error Correction: use Screaming Frog SEO Spider (Duplicate Content) to analyze the content on your website and Copyscape to check your content for plagiarism across the Internet.
Excessive SEO tactics often trigger the opposite effect.
Balance your optimization to maintain the natural flow of the text.
Error Correction: Use tools like Surfer SEO to analyze keyword density and maintain a natural content flow.
The proper length of meta tags:
- Meta title: up to 60-70 characters and include keywords;
- Meta descriptions: 120-170 characters and include keywords.
No meta tags or wrong tag lengths are basic mistakes. Remember, Search engines rely on meta tags to understand and show a page’s content in the search results. The right format of meta tags will help increase click rates.
Error Correction: Descriptions must be well-composed, within the estimated length, include target keywords, and reflect the content and page intent.
Are you giving enough attention to your website’s speed? A slow-loading page can have several negative impacts, including:
Error Correction: Improve page load speed with tools like Google PageSpeed Insights, GTmetrix, or Lighthouse by optimizing images, leveraging browser caching, and reducing unnecessary scripts.
We identified one of the most neglected elements – Alternative text or Alt text. Alternative text is essential for every image you put on the website. Without it, search engines won’t notice your media content, and you will miss out on traffic through image search.
Error Correction: Use tools like Screaming Frog SEO Spider to identify missing alt text on images.
Internal linking is an SEO element that helps search engines index your site and evaluate page weight. Internal linking mistakes may result in a lack of weight on high-priority pages and remaining wholly ignored in the search rankings.
Error Correction: Use tools like Ahrefs or SEMrush to analyze your internal linking structure and ensure that high-priority pages are well-linked within your content
Backlinks are one of the main signals search engines use to determine your site’s authority.
Missing, irrelevant, or low-quality backlinks ruin your SEO strategy, resulting in low site visibility and organic traffic loss.
Search engines evaluate:
- number of backlinks;
- quality;
- relevance of the resources;
- the anchor text.
Error Correction: Use tools like Ahrefs to analyze and disavow toxic backlinks and focus on building high-quality backlinks from authoritative and relevant sites using guest posting or digital PR.
To win over the competitors in 2025, you need a deep understanding of every SEO strategy. Both on-page SEO mistakes and off-page SEO mistakes cause significant troubles for projects in every niche.
However, the error correction will improve your project’s visibility right away. Success belongs to those who learn from their mistakes, not those who never make them!
