What is Search Engine Optimisation (SEO)
Now Let’s talk about what SEO exactly is?
SEO stands for Search Engine Optimisation, as a beginner or newbie in SEO I hope you know the meaning of SEO.
SEO is a part of the whole digital marketing industry, that has been using non-paid tactics to improve any website ranking and visibility in SERP (Search Engine Result Page).
SEO also helps you to improve EEAT (expertise, experience, authority, and trustworthiness) in search engines and user’s minds.
By improving the performance, experience, and authority of your website so it can gain better visibility in search engines like Google.
Let’s talk about EEAT for a little bit.
Experience: Google looks for content created by people with real-life experience in the topic. For example, if someone writes about travel, have they been to those places? This adds depth and makes the information more genuine.
Expertise: This is about knowledge. Does the writer have a background in the field? Whether it’s qualifications, training, or years spent working in a certain area, expertise shows that the creator knows what they’re talking about.
Authoritativeness: Think of authority as reputation. Is the writer or website well-regarded in their field? When people see it as a trusted source, it strengthens the quality of the content. This is why credible news outlets or specialised websites often rank highly.
Trustworthiness: Readers need to feel confident that the information is accurate, honest, and safe. From a secure website to well-researched facts, trustworthiness is essential—especially for topics that impact health, finance, or legal decisions.
These factors—E-E-A-T—are especially crucial for “Your Money or Your Life” (YMYL) topics, where the stakes are high, like medical advice or financial guidance. Google wants to make sure that this type of content is reliable and safe for users.
If I talk about it in particular, SEO is a process or art that helps you rank higher organically (not paid advertisement) in search engines.
To understand what is SEO now I would like to show you what types of results are showing in SERP.
Understand The SERP- Search Engine Result Page
Let’s jump to the SERP. SERP stands for Search Engine Result Page. If you have a browser and you are using Google, now you type a query on the Google search box.
After entering your query you will see a page which is included with a lot of information. That is called SERP.
As an SEO learner, you have to learn more details in SERP. now jump to the point is types of results in SERP.
There are 2 types of results available in SERP
There are two types of results available in the SERP. Paid results and Organic results. Now we are going to break each one.
Paid Results
Paid results are essentially ads. Companies pay search engines to display their website at the top or bottom of the SERP for specific keywords.
They’re usually labeled as “Ad” or “Sponsored” and appear prominently to catch the user’s attention. As I provided an image on the above.
Paid results are a way for businesses to gain instant visibility without waiting for organic rankings, but they’re only visible as long as the company continues to pay search engines.
Organic Results
On the other hand, organic results are unpaid results that show up naturally based on how relevant they are to what you searched for.
These results get ranked based on factors like content quality, keyword implementation, and user engagement and thats the magic of SEO.
While it can take time to rank organically on SERP, these results often feel more trustworthy since they’ve earned the top position organically, not bought, and it can bring long-term visibility without going any paid to search engines.
Why is SEO Important?
If you are doing online business or want to start making money online SEO could be your best choice in 2025. Let’s talk about both.
For Business
There are lots of SEO agencies that provide SEO services for small businesses or e-commerce businesses. I have provided you with the market size of SEO. SEO is the biggest part of Digital Marketing.
SEO and paid ads each play a valuable role in marketing, with SEO focusing on organic reach while paid ads provide targeted visibility.
Paid ads can provide quick, targeted results, while SEO builds lasting visibility and trust over time. Together, they create a balanced marketing approach.
Imagine you have a small cat food business without a physical showroom, maybe just a small shop. You’re considering using ads to boost sales, which can be helpful at first for getting initial sales or leads.
But here’s the catch: when you start advertising, you might not get the results you expected. For example, you might spend £1000 expecting 150-200 sales or leads. Yet, after spending that £1000, you realise that this budget isn’t enough to compete with bigger brands with larger ad budgets.
Now, consider this: if you invested that same £1000 in SEO, your website could start ranking at the top of search results over time.
Once you reach that spot, you could see up to double the revenue without needing to keep spending heavily on ads.
SEO takes time but can lead to a steady stream of organic customers, giving your business sustainable growth for the long term.
Learning SEO and understanding what Google values can help you grow your business profitably without spending on ads. If you’d rather not handle SEO yourself, there are many SEO agencies ready to help like us.
Keep in mind, that SEO is a long-term investment—it takes time to see returns, but when done right, it can bring profits for years to come.
For Career
If you look at the people who are surrounding you. You can see that 70% of those people have digital skills.
In this competitive era definitely you have to acquire a digital skill that doesn’t contain your academic skills. If you do not have any digital skills you can not compete with this digital world. It can be challenging to stay relevant in today’s digital world.
So, SEO is one of the best of them (skills), if I particularly SEO is the core of digital marketing. If you learn the skill properly you can make your career bright.
How Search Engines Work
Search engines operate using three main processes: crawling, indexing, and ranking. Each step is essential in helping search engines find, organise, and display content when someone enters a query.
What is Crawling
Crawling is the first step, where search engines use “bots” or “spiders” (whatever you can call them) to scan the internet for new content.
These bots go from link to link, discovering new pages and revisiting existing ones to check for updates.
If your website isn’t crawled, it won’t appear in search results, so it’s essential to ensure your site is accessible and well-linked.
How Does Indexing Work?
After a page is crawled, it goes into indexing. Every search engine has a database or data center. This is when the search engine organises and stores the content it’s found in a massive database, known as the index.
The search engine when indexing your pages bots are looking at how relevant and user-friendly that page is.
During indexing, the search engine tries to understand what each page is about and then focuses on keywords, images, and structured data.
If a page doesn’t get indexed, it won’t be eligible to show up on the search engine results page.
Let's See What is Ranking
Finally, we have ranking. After crawling and indexing properly the search will rank you.
When someone searches for a term for example “Beginners SEO Guide”, the search engine sorts through its index to find the most relevant pages, ranking them based on hundreds of factors like relevance, authority, and user experience.
Pages with higher relevance and quality get a better chance of appearing at the top of the results, which is why optimising for SEO is key.
3 Reasons for SEO Matters
Drive More Traffic
One of the primary reasons SEO is essential is its ability to drive more traffic to your site.
Effective SEO helps your website appear prominently in search results, which means more people are likely to click through to your content.
Higher click-through rates (CTR) directly correlate with increased traffic, giving you more opportunities to reach potential customers, share information, or connect with your audience.
Think of it as opening more doors for people to find your business. In the first position, you can get 39% CTR from your potential.
Here is the image of CTR by filtering position.
Increase Brand Awareness
When your website consistently appears on the first page of search results, more people will see your brand name, logo, and messaging.
This constant visibility builds brand awareness, making your business more recognisable and memorable over time.
With SEO, you’re not just reaching people ready to buy; you’re also capturing the attention of potential customers, setting the stage for future engagement and loyalty.
Build Authority Online
When you rank highly for relevant searches, people see your site as an authority, especially if your content is informative, helpful, and trustworthy.
High-quality backlinks, consistent content, and good user experience contribute to this sense of authority.
As your website’s authority grows, it not only improves your rankings but also builds trust with your audience, increasing the likelihood of conversions and customer loyalty.
