SEO, or Search Engine Optimization, focuses on improving your website and content so you can show up organically in search results. This includes things like optimizing keywords, improving site speed, creating valuable content, and building credibility so Google naturally ranks you higher without paying for placement. SEM, or Search Engine Marketing, uses paid strategies to drive traffic. This typically includes Google Ads, pay per click campaigns, and other forms of paid search advertising that place your business at the top of search results instantly. In short: SEO builds long term organic visibility, while SEM gives you immediate visibility through paid ads. Both can work together for a strong search strategy.
