Pair that with behavioral signals like bounce rate to spot where friction is causing abandonment.\"}}, {\"@type\": \"Question\", \"name\": \"Why do mobile issues hurt local businesses more?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Because local searches often happen on phones with immediate intent.

In practice the effect was real but page-specific, so mobile-friendly templates kept their visibility while legacy templates lost mobile rankings.\"}}, {\"@type\": \"Question\", \"name\": \"Did the 2015 update apply page by page or to the whole site?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Google evaluated each URL individually for mobile usability rather than grading the entire domain. This is why large sites saw mixed results, with mobile-friendly templates winning and legacy templates losing, and why one bad template could sink a whole content section.\"}}, {\"@type\": \"Question\", \"name\": \"How did the Mobile-Friendly update classify pages in 2015?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Early Mobilegeddon behavior was essentially binary, meaning a page was either mobile-friendly or it was not. Google provided the Mobile-Friendly Test so site owners could check a page and get direct pass or fail usability feedback.\"}}, {\"@type\": \"Question\", \"name\": \"What usability problems did the Mobile-Friendly update target?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It targeted practical device problems such as text too small to read without zooming, touch elements placed too close together, layouts that broke without responsive rules, and heavy assets that slowed loading. It also penalized reliance on tech that mobile devices could not support well.\"}}, {\"@type\": \"Question\", \"name\": \"Did the Mobile-Friendly update affect desktop search results?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The update initially applied only to mobile search results, so desktop rankings could stay stable while mobile traffic dropped. This separation was an early sign that Google was building distinct evaluation pipelines, which later unified under mobile-first indexing.\"}}, {\"@type\": \"Question\", \"name\": \"How does the 2015 update relate to Core Web Vitals today?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Mobilegeddon set the usability baseline, and later updates expanded mobile evaluation into measurable experience signals. Core Web Vitals turned that experience into specific metrics, Largest Contentful Paint for loading, Cumulative Layout Shift for visual stability, and Interaction to Next Paint for responsiveness.\"}}]}","footnotes":""},"categories":[166],"tags":[173],"class_list":["post-9315","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-terminology","tag-search-engines-algorithm-updates"],"yoast_head":"<!--
