What is SEO (Search Engine Optimization)?
Search Engine Optimization, or SEO, is a method of improving a website’s visibility in search engine results pages (SERPs). It involves techniques and creative strategies to improve rankings, attract organic traffic, and increase the quality and quantity of visitors.
In other words, SEO is also about increasing the standard and total website traffic. As you improve your position in search engines, you’ll likely get more visitors who may be engaged in your website, its products, or its content.
For the best explanation, we can use a real example. For instance, if you search for the term ‘best AC service providers’ on Google, Google will show you the top-ranking website for your keyword. Google shows these results for free, and the number of visitors coming through this is called organic traffic.
Why is SEO Important?
Catering to a Huge Audience
Most online approaches begin with a search engine. Ranking high means visibility in front of a wide, global audience actively searching for your products or services.
Low Cost of Implementation
Compared to paid advertising, SEO is cost-effective in the long run. You pay with time and effort upfront, but you can enjoy consistent traffic once you rank.
Staying Ahead of the Competition
Your competitors are investing in SEO. If you don’t, you’re handing them an advantage. SEO helps you stay relevant and ahead in a competitive online landscape.
Enhance User Experience
Good SEO practices improve user experience. You can please Google and your visitors by offering fast load speeds, mobile optimization, and easy navigation.
Builds Trust and Credibility
Sites that rank well are considered more trustworthy by users. Authority backlinks, quality content, and user-friendly design contribute to your reputation.
Data and Analysis
SEO provides valuable insight into user behaviour through tools like Google Analytics, Search Console, and Heatmaps.
How Does a Search Engine Work?
Search engine tools like Ecosia, Bing, StartPage, Google and DuckDuckGo are important systems that help users find accurate information quickly with accuracy. They follow a multi-step process that includes crawling, indexing, and ranking. Let’s break it down:
Crawling
Crawling is the first step in the process. Search engines send out automated bots known as crawlers or spiders to discover content across the web. These bots move from one page to another via links, collecting information such as:
- Page titles
- Meta tags
- Image alt texts
- Content structure
- Internal and external links
Search engines start with a known list of URLs (called a seed list) and, crawl those pages, then follow hyperlinks on those pages to discover new content. Crawling helps search engines discover which websites exist and what they contain.
✅ Example: Googlebot is Google’s main crawler. It continuously explores the internet, discovering new content and re-crawling updated pages. In the below as you can see, google has crawled and index your post.
Indexing
Once the content is crawled, it needs to be understood and stored. This process is called indexing. The data collected by crawlers is organized and added to the search engine’s massive index — essentially a digital library of all known web pages.
During indexing, search engines analyze:
- Page content and topic
- Keywords and keyword context
- The freshness of the content
- Multimedia content like images or videos
- Page structure (HTML, headings, schema, etc.)
Search engines also use semantic indexing, which helps them understand the exact keyword and its context and intent.
⚠️ Note: If your page is not indexed, it won’t appear in search results — even if it’s well-designed or keyword-optimized. In the below image page is not index.
Ranking
When a user search a query into a search engine, it searches its index to find the most relevant pages. This is where the ranking algorithm comes into play.
The algorithm uses hundreds of ranking signals (Google has over 200) to evaluate and sort results. Tops of the most important ranking factors include:
- Keyword relevance
- Page authority (backlinks)
- Mobile-friendliness
- Page load speed
- Secure connection (HTTPS)
- User engagement signals (click-through rates, dwell time)
- Content quality and originality
Search engines try to match the user intent (informational, navigational, or transactional) with the most helpful and trustworthy pages. The goal is to show the best possible answer at the top of the search results.
How Do Search Engines Find Your Pages?
This tool helps you send a request to Google to crawl your website. You can also submit sitemaps for your site and monitor the number of submitted pages added to Google’s index and other details.
Why Sites Don’t Show Up in Search Results?
- Noindex tag present
- Poor content quality
- Blocked by robots.txt
- Lack of backlinks
- Penalty from algorithm updates
What is the Search Engine Algorithm?
Search engines use algorithms to decide the most relevant results for a query.
i. Analyze User Query
Search engines try to explain the intent behind a search query (informational, transactional, or navigational).
ii. Finding Matching Pages
The engine matches the query with indexed pages based on keywords, relevance, and authority.
Why Search Engines Sometimes Display Faulty/No Results?
This happens when the content doesn’t match user intent, is poorly optimized, or lacks authority.
How SEO Works?
SEO works by optimizing various website elements so search engines can explain their relevance and value to user queries. It starts with identifying what people are searching for—using keyword research—and then tailoring your website’s content, structure, and technical setup to target those search terms. By doing this, search engines are more likely to rank your pages higher, bringing in more organic traffic.
For example, run a bakery in Delhi and optimize your site with keywords like “best cakes in Delhi.“ Add quality content about your products, fast loading speed and mobile-friendliness. Google will find your site more valuable for people searching those terms. Over time, you may appear on the first page, attracting customers without paying for ads.

How do you do keyword research for SEO?
1. What is the role of Keyword research in SEO, and why does it play an important role?
Keyword research is one of the most important aspects of SEO because it directly impacts how well your content ranks on search engines. Acknowledging what your audience is searching for helps you create relevant and optimized content for those specific queries. By knowing the search intent that regular visitors are looking for, you can tailor your website’stciles, blogposts, and services pages to target those particular keywords.
It increases your organic traffic and ensures that the content you produce meets the needs and interests of your audience. For instance, if you’re running an online store that sells sneakers, performing keyword research can reveal terms like “best running shoes for flat feet“ or “affordable sneakers for men,“ which you can target in your content to increase visibility in search results and attract more customers.
The below is the example for top searches.
2. Brainstorming for Keywords
Brainstorming for keywords is the initial step in the keyword research process, and it involves thinking about your business, niche, and the potential questions your audience might have. Start by creating a list of broad topics related to your industry, products, or services. These could be things like “digital marketing,” “healthy eating,“ or “home improvement tips.“ Once you have a list of broad topics, you can break them down into more specific subtopics or long-tail keywords.
For example, from “digital marketing,“ you could narrow down to “SEO services,” “email marketing tips,“ or “social media strategies.“ This helps identify general and specific search intents that people might use when looking for solutions in your area of expertise.
3. What are some things to know before finding a suitable keyword? (Competitor’s Keywords Analysis)
It is important to find the most suitable keyword. It involves not only brainstorming but also analyzing your competition. By gathering your competitors’ keywords for which they are ranking, you can gain valuable insights into what works and which topics have significant search volume. Tools like Ahrefs, Semrush, and Moz allow you to analyze your competitors’ keyword strategies. You can enter their websites using these tools to see which keywords they rank for, how much traffic they’re receiving, and the difficulty level of ranking for these terms.
For example, if you find that your competitor’s blog is ranking for the keyword “best-running shoes for long-distance runners,” this could indicate high interest in this topic. You can use this information to target the same or similar keywords in your content, adjusting your approach to make it more compelling or detailed to improve your chances of outranking them.
Competitor analysis gives you a competitive edge and can highlight keyword opportunities that you might not have considered otherwise.
