What Are Common SEO Mistakes, and How Can You Avoid Them?

Common SEO mistakes include deliberately stuffing keywords, leaving page titles and descriptions blank or reusing them, neglecting heading structure in long articles, and leaving broken links after URLs change. To avoid these mistakes, include content, page information, and link checks in your publishing workflow rather than focusing only on whether keywords appear. If you use AI to help with writing, verify the information rather than treating fluent prose as a guarantee of accuracy. The following guidance can serve as a checklist before implementation, but completing it does not guarantee rankings.

More keywords do not make content more useful

In a 2021 article, Tenten listed keyword overuse as a common mistake and recommended prioritizing useful content, then incorporating keywords naturally. This advice is useful as a writing check, not as a formula that links keyword counts to rankings.

• First, check whether the article answers readers’ questions, then check whether keywords appear naturally.
• Check whether any sentences were added merely to repeat the same phrase without providing new information.
• For example, when introducing a service, explain what it includes rather than repeatedly inserting its name into every paragraph.

Check page titles, descriptions, and content headings separately

These three elements should not be conflated: page titles identify pages, meta descriptions provide summary text, and H1, H2, and H3 headings organize the content. Tenten’s article recommends creating a unique title and description for each page and notes that a lack of headings makes long articles harder to read and understand.

• Check each page for missing titles and descriptions or text reused from other pages.
• Organize long articles with headings by topic so readers can find the sections they need.
• Do not use the fact that search engines may extract their own snippets as a reason to omit descriptions; the extracted text may not convey the page’s intended key points.

These are practical steps to take before publishing, not grounds for asserting that duplicate descriptions necessarily cause rankings to drop.

After changing a URL, check where links ultimately lead

Deleted pages, changed URLs, and unavailable external destinations can all leave unusable links. Tenten recommends running another SEO audit after making repairs; the point is not merely to finish the changes, but to verify that the links work.

Checks should also follow redirects to their final destinations. Screaming Frog’s version 23.0 release notes state that its error inlinks export can bring together links with no response, 4XX responses, and 5XX responses. Separate reports check redirects whose final destinations are blocked or return errors. These are tool features in that version, not search engine ranking rules, and setting up a redirect alone does not mean a URL has been fully fixed.

AI can help with writing, but it cannot replace verification

In a 2023 article discussing AI tools available at the time, awoo warned that generated content could sound confident while containing incorrect information and could remain limited to information that others could readily compile again. The author recommended using practical experience and expertise as source material without rejecting AI-assisted writing. In practice, verify important statements and retain verifiable expert content; if you lack firsthand experience, do not write as though you personally tested or used something.
