If you do not prepare for it, the risk of losing traffic and search rankings is very real. One thing matters: most often traffic drops not because of the new design but because of technical changes nobody tracked: changed page addresses without redirects, missing texts and a version of the site closed from indexing.<\/p>\n<h2>Why a redesign can lower traffic<\/h2>\n<ul>\n<li><strong>Page addresses changed.<\/strong> Without correct redirects old URLs return an error, and the accumulated \u201cweight\u201d of the pages is lost.<\/li>\n<li><strong>Texts disappeared or shrank.<\/strong> Pages that ranked thanks to their content lose it together with their positions.<\/li>\n<li><strong>Structure and internal links changed.<\/strong> Search engines understand worse which pages matter.<\/li>\n<li><strong>The block on indexing stayed.<\/strong> A test version is closed from search, and after launch nobody remembers to open it.<\/li>\n<li><strong>Metadata was lost.<\/strong> Titles, descriptions and markup were not moved to the new pages.<\/li>\n<li><strong>The new site is slower.<\/strong> Heavy effects and scripts worsen speed and usability.<\/li>\n<li><strong>Content search cannot see.<\/strong> Text is loaded by scripts and crawlers do not read it.<\/li>\n<\/ul>\n<h2>What to do before the work starts<\/h2>\n<ol>\n<li><strong>Record the current state.<\/strong> Save data on traffic, positions, indexing and leads from Search Console and analytics.<\/li>\n<li><strong>Make a full list of the site\u2019s addresses.<\/strong> Crawl the site to collect all pages with their titles, descriptions and H1.<\/li>\n<li><strong>Identify the pages that bring traffic and leads.<\/strong> Protect them first.<\/li>\n<li><strong>Keep working texts and metadata.<\/strong> Do not rewrite what ranks without a reason.<\/li>\n<li><strong>Write down the internal link structure.<\/strong> Important pages should stay reachable from the same places.<\/li>\n<li><strong>Record speed.<\/strong> The new version should not be slower than the old one.<\/li>\n<\/ol>\n<p>If you are not sure where to start, an <a href=\"https:\/\/www.theonebly.com\/en\/services\/seo\/seo-audit\/\">SEO audit<\/a> before the redesign will help.<\/p>\n<h2>What to take into account during development<\/h2>\n<ul>\n<li><strong>The test environment is closed from search.<\/strong> This is right during development, but you need to remember it before launch.<\/li>\n<li><strong>Keep the address structure.<\/strong> If addresses change, prepare a full redirect map from old pages to new ones.<\/li>\n<li><strong>Move metadata and markup.<\/strong> Titles, descriptions, Schema.org, canonical.<\/li>\n<li><strong>Do not remove content that works.<\/strong> You can simplify pages, but not lose their search substance.<\/li>\n<li><strong>Keep internal linking.<\/strong> Menus, breadcrumbs and links in the text should lead to the same important pages.<\/li>\n<li><strong>Take care of languages and regions.<\/strong> If the website is multilingual, check hreflang on all versions.<\/li>\n<li><strong>Watch speed and the mobile version.<\/strong> We describe the technical foundation in our <a
