SEO is what helps a website appear higher in Google than others. Or, more simply, it is a set of actions that help people find your website in searches. But even in 2025, many websites make the same mistakes that cause them to lose visitors, sales, and search engine trust.

Mistake #1: Wrong or too general keywords

Imagine you sell handmade wooden chairs, and you use the word "furniture" on your site. That's too general. People searching for "furniture" might be looking for cabinets, sofas, or kitchens. You're not quite that.

It's also common that the keywords simply don't fit the topic of the page or are just plucked out of thin air.

How not to make mistakes with keywords:

  • Collect semantics – use Google Keyword Planner, Serpstat, Ahrefs or Ubersuggest.

  • See what people enter in search (use Google Search Console).

  • Avoid too broad phrases like "Internet", "clothes", "services".

  • Choose phrases with intent: for example, buy a handmade wooden chair Lviv.

  • And most importantly - do not push the keys anyhow. They should sound natural.

Mistake #2: Content – so that it exists

In 2025, Google will be better at recognizing whether a text is actually useful to people. If a page only contains a set of words and essentially nothing, the chances of getting to the top are slim.

Many sites still write texts “for show”: without structure, with fluff and a bunch of repetitions of keywords. You don’t want to read such texts, which means there’s no point in them.

How to make content better:

  • Write simply. In human language. Like now :)

  • Answer real customer questions.

  • Use lists, subheadings, quotes, examples.

  • Add images, infographics, short videos – this improves perception.

  • Don't fill in the blanks. Better less, but in fact.

Mistake #3: Surprising URLs

URL is the address of the page that both the user and the search engine see. For example:

Badly:
https://site.com/index.php?page=293&itemid=2
Fine:
https://site.com/derevyani-stilci-lviv

The clearer the URL, the better. Not only is it convenient, but it also helps with SEO.

URL Recommendations:

  • Make short and logical addresses.

  • Do not use unnecessary numbers, symbols or Cyrillic.

  • Separate words with hyphens ( - ), and not by underlining ( _ ).

  • Include the keyword if it is relevant.

  • Don't change the URL unnecessarily - it affects indexing.

Mistake #4: Confusion in the site structure

Imagine a store without signs, departments and salespeople. To find the right product, you will have to run around all the rooms. Such a site is a nightmare for the user and the search engine.

Search engines love a clear and logical structure. And also navigation that helps the user find what they need quickly.

How to make the structure understandable:

  • Divide content into sections and subsections.

  • Add menus and breadcrumbs (navigation at the top).

  • Create a sitemap (XML Sitemap) and add it to Google Search Console.

  • Keep it simple: everything should be intuitive.

Mistake #5: Low-quality or copied content

Google is actively fighting duplicates and empty content in 2025. If the text does not add value, it simply will not be seen.

Copied text from other sites is the worst thing you can do. Such pages almost never make it to the TOP.

How to create quality content:

  • Write your own texts that are truly useful for your audience.

  • Use statistics, experience, cases - something that others do not have.

  • Update content regularly (once every few months is enough).

  • Avoid artificial "spamming" with keywords.

Mistake #6: Slow Site

In 2025, page loading speed is one of the important ranking factors. If a site takes a long time to load, the user leaves. And Google with him.

This is especially true for mobile devices. Now imagine that 70% of traffic comes from phones...

How to speed up a website:

  • Optimize the image (smaller size without losing quality).

  • Use caching.

  • Disable unnecessary plugins (if WordPress).

  • Use fast hosting.

  • Check the site through PageSpeed Insights.

Mistake #7: Lack of Internal Links

Internal links are like bridges between pages. They help the user find more useful information on the site, and Google better understands the structure of the resource.

Many people simply forget about this. And in vain.

Examples of good internal links:

  • On the product page, provide a link to the article "how to choose a size".

  • At the end of the article, add a "Read also" block.

  • Link thematic pages, blogs, and categories.

Summary Table: Top SEO Mistakes and How to Avoid Them

Error What's wrong How to fix
Incorrect keywords Too general or inappropriate Research queries + narrow relevant phrases
Weak content Texts without benefit or "for the sake of appearance" Write in an interesting, structured way and for people
Confused URL Unreadable addresses with signs and numbers Make short and logical addresses with keywords
Poorly thought out website structure It is difficult for a search engine to "read" the site Categories, subcategories, site map
Duplicate or copied text Search engines see this and lower their rankings. Unique content with added value
Slow loading Users don't wait Optimize speed (image, cache, hosting)
No internal links Pages are isolated Link content together

Conclusion

SEO is not just about technical nuances. It is about people, convenience and usefulness. In 2025, search engines understand what the user wants more than ever. And if your site really answers their request, you will get your positions, clicks and sales.

So the main rule: make a site for people, but do not forget about search engines. And it is better to fix mistakes today than to look later for why traffic has dropped.
