Different devices have varying screen sizes, capabilities, and user behaviors, making it essential to analyze keyword trends for SEO across different devices such as desktop, mobile, and tablet. Tools such as those mentioned can help filter and compare keyword trends by device to observe how they influence SEO performance. When optimizing content and keywords for SEO, factors to consider include mobile-friendliness, voice search, and location-based search. Mobile-first indexing by Google prioritizes the mobile version of websites for ranking and crawling; thus, it is important that your website is responsive, fast, and user-friendly on mobile devices with content and keywords that match the mobile search intent. Voice search queries are longer, more conversational, and more question-based than typed queries; thus, content should be optimized for voice search with natural language, long-tail keywords, and FAQ formats. Location-based search is more common on mobile devices as users often look for nearby businesses; thus, it is important to optimize content and keywords for local search with geo-specific keywords, local citations, and schema markup.
