What Is SEO (Search Engine Optimisation)? A Plain-English Guide

SEO is how you get your website found on Google without paying for every click. Here's how it works, explained without the jargon.

Search engine optimisation, or SEO, is the practice of improving your website so it appears higher in Google's free (organic) results when people search for things related to your business.

How Google decides what to show

Google's goal is to show the most helpful, trustworthy result for each search. To judge that, it looks at hundreds of signals, which fall roughly into three groups:

• Relevance: does your page actually answer what the person searched for?
• Quality and experience: is the page fast, mobile-friendly, secure and easy to use?
• Authority and trust: do other reputable websites link to you and mention you? Do you have genuine reviews?

The three pillars of SEO

Technical SEO

Making sure Google can crawl, understand and index your site: speed, mobile-friendliness, sitemaps, structured data and fixing errors.

On-page SEO

Writing helpful content and optimising titles, headings, descriptions, images and internal links around the topics your customers search for.

Off-page SEO

Building authority through quality backlinks, business listings, reviews and brand mentions.

Why SEO is worth it

Unlike ads, you don't pay for each click. Once you rank, your pages can bring in customers for months or years. It takes time, usually three to six months to see real movement, but it compounds.

Seo FAQ

How much should a small business spend on digital marketing?

Start from how much a new customer is worth and what you can afford to pay per lead. Many small businesses begin with ₹15,000 to ₹50,000 a month across fees and ad spend.

Which social media platform is best for my business?

The one your customers use and where you can post consistently. B2B firms often do best on LinkedIn, while retail, food and lifestyle brands usually focus on Instagram and Facebook.

Is Google Ads or SEO better for my business?

Google Ads brings leads quickly while you pay for clicks; SEO takes longer but builds traffic that does not stop when the budget does. Many businesses use ads for quick wins while SEO grows.

How do I know if my marketing is working?

Track enquiries, sales and cost per lead for each channel. If a channel brings traffic but no enquiries, the problem is usually the offer, the landing page or the follow-up.

What is local SEO?

Local SEO helps you appear when people nearby search for your service, especially in the Google Maps results. It relies on your Google Business Profile, reviews, local pages and consistent contact details.

How long does SEO take to show results?

Most businesses see early movement within two to three months and more meaningful results between four and twelve months, depending on competition and the state of the website.
