What Is SEO?
Search Engine Optimization (SEO) is the process of improving your website’s organic (unpaid) visibility on search engines like Google. The goal is to earn traffic by ranking higher in search engine results pages (SERPs) without paying for ads.
Core Components of SEO:
- On-Page SEO: Optimizing content, meta tags, headers, and keyword placement.
- Technical SEO: Enhancing site speed, mobile-friendliness, indexing, and crawlability.
- Off-Page SEO: Earning backlinks, improving domain authority, and building trust.
- Content Strategy: Publishing valuable, keyword-rich content that answers searchers’ questions.
What Is SEM?
Search Engine Marketing (SEM) is a broader strategy that includes paid search advertising to appear in search results. It’s sometimes used interchangeably with PPC (pay-per-click), though SEM can refer to both paid and organic search efforts.
Key Components of SEM:
- Google Ads (PPC): Bidding on keywords to show ads in search results.
- Ad Copywriting: Crafting compelling ad text to drive clicks.
- Landing Page Optimization: Creating high-converting pages for ad traffic.
- Budget & Bidding Strategy: Managing ad spend for maximum ROI.
