While the term historically referred to both organic search activities\u2014like <a href=\"https:\/\/asiasearch.co.th\/what-is-seo\/\">Search Engine Optimization (SEO)<\/a>\u2014and paid advertising, it now almost exclusively refers to paid search advertising, often called Pay-Per-Click (PPC) advertising.<\/p>\r\n\r\n\r\n<div class=\"wp-block-image\">\r\n<figure class=\"aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"900\" height=\"500\" class=\"wp-image-6377\" src=\"https:\/\/asiasearch.co.th\/wp-content\/uploads\/2023\/09\/search-engine-optimization-research-infomation-technology-concept.jpg\" alt=\"SEM\" srcset=\"https:\/\/asiasearch.co.th\/wp-content\/uploads\/2023\/09\/search-engine-optimization-research-infomation-technology-concept.jpg 900w, https:\/\/asiasearch.co.th\/wp-content\/uploads\/2023\/09\/search-engine-optimization-research-infomation-technology-concept-300x167.jpg 300w, https:\/\/asiasearch.co.th\/wp-content\/uploads\/2023\/09\/search-engine-optimization-research-infomation-technology-concept-768x427.jpg 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/figure><\/div>\r\n\r\n\r\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_is_SEM_Important\"><\/span>Why is SEM Important?<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n\r\n\r\n\r\n<p>With more people searching for products, services, and shopping online each year, SEM has become a critical strategy for reaching potential customers efficiently. In fact, most new website visitors find businesses through search engines like Google, where they can instantly discover relevant websites offering exactly what they\u2019re looking for.<\/p>\r\n\r\n\r\n\r\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">In SEM, advertisers only pay when their ads generate clicks, making it a highly cost-effective way to appear on the first page of search results.<\/blockquote>\r\n\r\n\r\n\r\n<p>This makes SEM a primary driver of targeted traffic, boosting opportunities to showcase products and increase sales.

In paid search advertising, sponsored ads appear prominently at the top and sides of search results\u2014making them more visible than organic listings generated through SEO (<a href=\"https:\/\/asiasearch.co.th\/seo\/\">SEO services to rank on the first page<\/a>).<\/p>\r\n\r\n\r\n\r\n<p>For example, if you\u2019re searching for a specific product or service, you enter targeted keywords into the search bar. The SERP will display paid ads from companies bidding on those keywords, often occupying the top positions for maximum visibility.<\/p>\r\n\r\n\r\n\r\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">These ads appear in prime positions alongside relevant search results, significantly increasing the likelihood of receiving clicks from potential customers.<\/blockquote>\r\n\r\n\r\n\r\n<p>Related reading: <a href=\"https:\/\/asiasearch.co.th\/en\/benefits-of-promoting-with-google-ads\/\">The Benefits of Advertising with Google Ads<\/a><\/p>\r\n\r\n\r\n<div class=\"wp-block-image\">\r\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"681\" class=\"wp-image-6378\" src=\"https:\/\/asiasearch.co.th\/wp-content\/uploads\/2023\/09\/seo-search-engine-analysis-seo-search-engine-optimization-concept-with-laptop-computer-ranking-traffic-website-internet-technology-business-company-1024x681.jpg\" alt=\"Paid search advertising\" srcset=\"https:\/\/asiasearch.co.th\/wp-content\/uploads\/2023\/09\/seo-search-engine-analysis-seo-search-engine-optimization-concept-with-laptop-computer-ranking-traffic-website-internet-technology-business-company-1024x681.jpg 1024w, https:\/\/asiasearch.co.th\/wp-content\/uploads\/2023\/09\/seo-search-engine-analysis-seo-search-engine-optimization-concept-with-laptop-computer-ranking-traffic-website-internet-technology-business-company-300x200.jpg 300w, https:\/\/asiasearch.co.th\/wp-content\/uploads\/2023\/09\/seo-search-engine-analysis-seo-search-engine-optimization-concept-with-laptop-computer-ranking-traffic-website-internet-technology-business-company-768x511.jpg 768w, https:\/\/asiasearch.co.th\/wp-content\/uploads\/2023\/09\/seo-search-engine-analysis-seo-search-engine-optimization-concept-with-laptop-computer-ranking-traffic-website-internet-technology-business-company-1536x1022.jpg 1536w, https:\/\/asiasearch.co.th\/wp-content\/uploads\/2023\/09\/seo-search-engine-analysis-seo-search-engine-optimization-concept-with-laptop-computer-ranking-traffic-website-internet-technology-business-company-2048x1363.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Steps to Create an SEM Campaign<\/h3>\r\n\r\n\r\n\r\n<p>SEM is typically a self-service process.
