Key Components:
On-Page SEO: This includes optimizing individual web pages to rank higher and earn more relevant traffic. Key practices involve keyword optimization, meta tags, header tags, and internal linking.
Off-Page SEO: This focuses on building a website’s reputation and authority through backlinks, social signals, and guest blogging.
Technical SEO: Ensures that a website meets the technical requirements of modern search engines with a focus on crawling, indexing, and rendering.
Benefits of SEO: SEO offers sustained, long-term visibility in search engines, improves credibility and trustworthiness, and provides a higher return on investment over time.

What is SEM?

Definition: SEM refers to the use of paid advertising on search engines to increase visibility and drive traffic to a website. This includes Pay-Per-Click (PPC) ads, display ads, and shopping ads.
Key Components:
- PPC (Pay-Per-Click): Advertisers pay each time their ad is clicked. This model is commonly used in Google Ads and Bing Ads.
- Display Ads: These are banner ads placed on websites across the internet, often through the Google Display Network, to reach a broader audience.
- Shopping Ads: These are product-based advertisements that appear in search engine results, particularly useful for e-commerce websites.
Benefits of SEM: SEM provides immediate visibility, precise targeting based on keywords, location, demographics, and user behavior, and is highly scalable depending on budget.

SEO Timeline:

Short-Term: Initial improvements in rankings may be observed within 3 to 6 months, depending on the competition and industry.
