What Is SEO and How It Works?
SEO, or Search Engine Optimization, is the practice and the process of optimizing your website so that it ranks higher in search engine results pages (SERPs), or search engine platforms like Google, Bing, and Yahoo. The ultimate goal is to increase organic (non-paid) traffic to your site.
How It Works
Search engines use algorithms to determine the most relevant and authoritative web pages for any given search query. These algorithms consider hundreds of ranking factors such as keywords, content quality, site speed, mobile-friendliness, user experience, and more.
Here’s a simplified step-by-step of how SEO works:
- Crawling: Search engine bots crawl web pages across the internet to collect data.
- Indexing: The collected data is indexed or stored in a massive database.
- Ranking: When a user types a query, the search engine retrieves relevant pages and ranks them based on relevance and authority.
Implementing SEO properly ensures your pages appear closer to the top of the SERPs, increasing visibility and driving traffic.
Types of SEO
For fully understand about what is SEO and how it works, you need to understand the different types of SEO. Each serves a specific purpose in improving your site’s ranking.
1. What Is On Page SEO?
On-page SEO refers to all optimization techniques applied directly to your website content. This includes:
- Using relevant keywords
- Creating high-quality, engaging content
- Optimizing title tags and meta descriptions
- Using proper headers (H1, H2, etc.)
- Internal linking structure
- Optimizing image alt tags
Essentially, on-page SEO is about making your content more readable and understandable—for both users and search engines.
2. What Is Off Page SEO?
Off-page SEO, on the other hand, involves external factors that impact your site’s credibility and ranking. This primarily revolves around backlinks in SEO—links from other websites pointing to your content.
Other off-page techniques include:
- Social media marketing
- Influencer outreach
- Guest blogging
- Online reviews and brand mentions
What is off page SEO in a nutshell? It’s about building your website’s authority and trustworthiness in the eyes of search engines.
3. What Is Technical SEO?
Technical SEO refers to backend improvements that help search engines crawl and index your site more efficiently. These include:
- XML sitemaps
- Mobile optimization
- Secure HTTPS protocols
- Fast page load speeds
- Structured data (schema markup)
- Eliminating duplicate content
Understanding what is technical SEO is vital because even the best content won’t rank well if your website has crawling or indexing issues.
The Role of Backlinks in SEO
One of the most critical components of search engine optimization is backlinks.
What Is Backlink in SEO?
A backlink is a link from one website to another. In SEO terms, backlinks act as “votes” of confidence. When reputable websites link to your content, search engines interpret it as a sign that your content is trustworthy and valuable.
There are two types of backlinks:
- DoFollow backlinks: Pass SEO value and help improve rankings.
- NoFollow backlinks: Do not pass SEO value but still drive referral traffic.
Why are backlinks in SEO so important?
Because Google’s algorithm weighs backlinks heavily when determining rankings. More high-quality backlinks = higher authority = better SERP rankings.
Tips to earn backlinks:
- Create shareable content
- Write guest posts
- Reach out to bloggers/influencers
- Get listed in online directories
- Use tools to find broken backlinks and offer your content as a replacement
