Moving away from Div-based layout in 2025: Semantic decline and growth of Google metrics

For many years, frontend development followed the fastest path: you need to make a visual block - wrap it in <div>. As a result, the DOM tree of most sites has turned into what Western engineers call Div-Soup (“soup of divas”) - a giant nesting doll of meaningless tags: <div class="container"><div class="row"><div class="col"><div class="card-inner">...</div></div></div></div>.

In 2025, this approach began to be considered deep legacy (outdated code). Semantic layout has ceased to be just a “rule of good manners” for geeks and has become a strict requirement from business metrics and Google algorithms.

Why Div-based layout drags the project to the bottom

Tag <div> (from English division) makes absolutely no sense. It's just an empty container.

1. DOM Size and Performance (INP/TBT): Excessive nesting makes it difficult for the browser to calculate styles (Recalculate Style) and render the page (Layout/Reflow). This directly impacts the Core Web Vitals (Interaction to Next Paint) metric - the site begins to “slow down” when scrolling and clicking on mobile phones.
2. Blindness for Screen Readers (a11y): People with visual impairments use screen readers (JAWS, NVDA). Screen reader can't read class="main-menu", he reads tags. Menu made on div, for a blind person looks like an unstructured piece of text.
3. AI Search Failure (Google SGE): Google's new generative neural networks (Search Generative Experience) parse not only text, but also the structure of the HTML page. If the content is not tagged <article> or <section>, the bot simply will not understand where the main idea begins and where the advertising banner begins, and will not include your site in the AI response.

What does correct semantics look like in 2025?

The trend has shifted to the use of strict semantic landmarks (Landmarks):

• <main> : A wrapper for the main, unique content of the page. There should only be one per page.
• <header> and <footer> : Headers and footers of a website or a specific article.
• <nav> : Navigation block. Attention: applicable only for the main links throughout the site (menus, breadcrumbs, pagination), and not for each list of tags.
• <article> : A completely independent block of content that makes sense even if taken out of the context of the site (News in the feed, card of a large product, weather widget).
• <section> : Thematic section within the document. Important: <section> must contain a title (from <h2> up to <h6>). If there is no title, it should be <div>.
• <aside> : Sidebar or content that is indirectly related to the main one (for example, promotion banners next to the article).

Codebase comparison:

❌ Div-Soup (Legacy):

<div class="header">Логотип</div>
<div class="content-wrapper">
  <div class="news-list">
    <div class="news-item">
      <div class="title">Новость дня</div>
      <div class="text">Текст из 152-ФЗ...</div>
    </div>
  </div>
</div>

✅ Semantic HTML5 (2025):

<header>Логотип</header>
<main class="content-wrapper">
  <section class="news-list">
    <!-- article авто-распознается ридерами как смысловой юнит -->
    <article class="news-item">
      <h2>Новость дня</h2>
      <p>Текст из 152-ФЗ...</p>
    </article>
  </section>
</main>

How component frameworks (Next.js / React) solve the problem

Previously <div> multiplied due to the limitations of CSS frameworks (like the old Bootstrap 3/4). Go to Utility-First CSS (TailwindCSS) in conjunction with the React ecosystem made it possible to encapsulate semantics inside components, radically reducing nesting:

// React-компонент карточки блога
export default function BlogPost({ title, excerpt }) {
  // Код чист, семантика сохранена, стили Tailwind добавлены прямо в компонент
  return (
    <article className="max-w-xl p-4 bg-white shadow-md rounded-lg">
      <h3 className="text-xl font-bold">{title}</h3>
      <p className="mt-2 text-gray-600">{excerpt}</p>
    </article>
  );
}

Moreover, using React Fragments (<>...</>) instead <div> when mapping arrays, it allows you to avoid creating unnecessary nodes in the DOM tree at all.

Summary

Refusal <div>-layout in favor of semantics is not a matter of code aesthetics. This is a strategic tool for reducing the cost of SEO. Pure semantic DOM:

1. Easier to use with search robots.
2. Guarantees high scores for Accessibility in Lighthouse.
3. Increases the chance of content being captured in Google SGE Quick Replies.
