Search engine optimisation (SEO) is the key to building a stronger online presence. It involves enhancing different aspects of your website so that it ranks higher in search results, boosting visibility and driving higher quality traffic and engagement with your products or services.
This guide outlines the core principles of SEO, from how search engines crawl and index websites to the growing impact of AI searches, and explores how businesses can use it effectively. Whether you are reworking an existing site or starting from scratch, an effective website with the right keywords, backlinks and interactive features can support your growth.
At Carrington, we deliver effective SEO strategies and digital marketing solutions that drive measurable results from landing page views to sales to support your business.
What is SEO?
SEO involves improving a website to optimise its performance on search engines like Google – whether this be the content, design, accessibility or another feature. Well-designed websites can drive higher quality traffic by directing users to helpful, relevant information and services based on their search.
Search engines create an index of websites, analysing components like texts, images and video files to build a database. When a user enters a search, the search engine crawls these websites and displays the most suitable results based on factors like key words and the domain authority – or reputability – of the site.
The visibility of your website depends on how well-organised and useful it is. How unique is your content? Have you included the search terms that your customers are most likely to use? Is the information detailed and up-to-date?
Websites are a key business tool to facilitate engagement and drive conversions like event sign-ups or product purchases. Simplifying the user experience with effective SEO strategies and techniques can help to generate leads and boost your online performance.
How is SEO changing?
SEO has undergone significant changes in recent years, as methods of searching are changing and search engines are growing more efficient in how they interpret search queries.
A key change is the role of AI in producing search results. This means users can now find information through platforms like ChatGPT, which can pull information from websites and present it to users without them leaving the app or window. Likewise, Google now has its Gemini AI model built into Google to answer questions in a similar way.
While these services do link to their sources, they also give users less reason to visit third party websites to find the answers to their questions, transforming the way people interact with the web.
Despite the accessibility of AI, person-driven SEO content strategies that showcases expertise, authority and trustworthiness may actually be more effective in engaging users for longer.
Practices like keyword stuffing are becoming less effective, as repeating terms excessively can reduce readability and negatively impact website performance. Businesses that prioritise real people, advice and clear messaging will be better equipped to adapt to changes in the SEO and digital marketing landscape.
The fundamentals of SEO for beginners
Keywords
Keywords allow search engines to understand what your website is about and when it should appear to users. Including these terms frequently across your website can improve its keyword ranking and relevance. For instance, including headers and titles that incorporate the right terms can guide users to you.
To determine which keywords are best for your business, you should try to anticipate the search terms that might lead to your services. Identifying your core audience and aligning content with user intent and your business goals is key.
It is important to avoid language that is not relevant, as there is no point in directing the wrong users to your platform. While popular search terms can increase visibility, they tend to be more competitive.
Using more specific terms can increase conversion rates, but niche terms have fewer searches so they’re less likely to deliver significant gains. For example, a business like Carrington might use a combination of terms related to our location like ‘Lincoln’ or ‘Lincolnshire’ and commercial services such as ‘marketing’, ‘PPC’, ‘SEO’ or ‘PR’. Alongside this, incorporating reviews, comments and real stories from customers or employees can help your website to stand out and build trust.
Website accessibility
When designing a website, you should prioritise accessibility. Using strong headings and a clear site structure can make it easier to navigate, both for search engines and individual users. You can also build simpler URLs that incorporate your keywords, rather than using overly complex links.
Keeping paragraphs short, such as two to four sentences, can ensure that the content is engaging and straightforward to scan. Maintaining consistent messaging will also contribute to a stronger brand identity.
Adding image captions, interactive features and a clear colour scheme and font can boost readability, while implementing mobile and desktop friendly elements will benefit your website design. If you need support with this, seek expert advice.
One of the most important, and most overlooked elements of accessibility and SEO, is the use of alt text for every image that’s on your website. Designed to help users with visual impairments, alt text should provide a description of each image but it’s also an opportunity to use the keywords and phrases that you’d like the page to rank for.
Up to date SEO website content writing
Search engines prefer to direct users to information that is up to date and contemporary, so if your website hasn’t been updated for the last five years, you’ll probably be losing out to sites that have fresher content.
Website blogs or news sections can be a great solution to having fresh, keyword targeted content for search engines to crawl. You should also make sure that pages are routinely updated, especially as the services and products your offer change over time.
Internal and external links
Links play an important role in strengthening the authority of your website, helping users to navigate it while improving the ability for search engines to crawl your site.
Internal linking is the simplest of these to establish, making sure that each page of your site links to other related pages. Internal links guide people to other pages that you own, encouraging them to engage with your business at length. Links can be placed as buttons or as links within the text that can direct users to relevant pages such as services or your contact page.
In contrast, outbound links lead to other websites. While you wouldn’t want users to follow a link that will take them away from your site, outbound linking can reinforce relationships with third parties, build an association between your site and theirs and improve your domain authority.
Likewise, inbound links can be even more effective still. These are links from other websites that lead to your site, directing traffic to your domain and establishing a connection. The value of these depends on the strength of the site that is linking to you and how appropriate it is. For example, a link from a respected national news website can be very valuable indeed, particularly if it is an article about a topic that’s directly related to what you do, but a link from a low ranking directory won’t have much value at all.
As well as the text that actually appears on your web pages, each page should also have underlying metadata which helps to describe what the page and the assets on that page are about. This includea a metadescription, which is a short summary of the page that search engines can display on results pages, encouraging users to visit.
