What is SEO?
Search Engine Optimisation (SEO) is the practice of increasing the number and quality of visitors to a website by improving rankings in the algorithmic search engine results.
Research shows that websites on the first page of Google receive almost 95% of clicks, and studies show that results that appear higher up the page receive an increased click through rate (CTR), and more traffic.
The algorithmic (‘natural’, ‘organic’, or ‘free’) search results are those that appear directly below the top pay-per-click adverts in Google, as highlighted below. There are also various other listings that can appear in the Google search results, such as map listings, videos, the knowledge graph and more. SEO can include improving visibility in these result sets as well.
How does SEO work?
Google (and Bing, which also power Yahoo search results) score their search results largely based upon relevancy and authority of pages it has crawled and included in its web index, to a users query to provide the best answer.
Google uses over 200 signals in scoring their search results and SEO encompasses technical and creative activities to influence and improve some of those known signals. It’s often useful to not focus too much on individual ranking signals and look at the wider goal of Google, to provide the best answers for its users.
SEO, therefore, involves making sure a website is accessible, technically sound, uses words that people type into the search engines, and provides an excellent user experience, with useful and high quality, expert content that helps answers the user’s query.
Google has a very large team of search quality raters that evaluate the quality of search results, that gets fed into a machine learning algorithm. Google’s search quality rater guidelines provide plenty of detail and examples of what Google class as high or low quality content and websites, and their emphasis on wanting to reward sites that clearly show their expertise, authority and trust (EAT).
Google uses a hyperlink based algorithm (known as ‘PageRank’) to calculate the popularity and authority of a page, and while Google is far more sophisticated today, this is still a fundamental signal in ranking. SEO can therefore also include activity to help improve the number and quality of ‘inbound links’ to a website, from other websites. This activity has historically been known as ‘link building’, but is really just marketing a brand with an emphasis online, through content or digital PR for example.
Relevant and reputable websites linking to a website is a strong signal to Google that it might be of interest to its users, and can be trusted to appear in the search results for relevant queries.
How to do SEO
SEO involves technical and creative activities that are often grouped into ‘Onsite SEO’ and ‘Offsite SEO’. This terminology is quite dated, but it is useful to understand, as it splits practices that can be performed on a website, and away from a website.
These activities require expertise, often from multiple individuals as the skillsets required to carry them out at a high level, are quite different – but they can also be learned. The other option is to hire a professional SEO agency, or SEO consultant to help in areas required.
Onsite SEO refers to activities on a website to improve organic visibility. This largely means optimising a website and content to improve the accessibility, relevancy and experience for users.
Offsite SEO refers to activities carried outside of a website to improve organic visibility. This is often referred to as ‘link building’, which aims to increase the number of reputable links from other websites, as search engines use them as a scoring as a vote of trust.
Links from websites and pages with more trust, popularity and relevancy will pass more value to another website, than an unknown, poor website that isn’t trusted by the search engines. So the quality of a link is the most important signal. There’s obviously a huge number of reasons why a website might link to another and not all of them fit into the activities above. This might include speaking at an event which is covered by local bloggers, sponsoring a local football team, or being listed by suppliers, as examples.
A good rule of thumb on whether a link is valuable is to consider the quality of referral traffic (visitors that might click on the link to visit your website). If the site won’t send any visitors, or the audience is completely unrelated and irrelevant, then it might not really be a link that’s worth pursuing.
The best and most sustainable approach to improve the inbound links to a website is earning them, by providing genuine and compelling reasons for websites to cite and link to the brand and content for who they are, the service or product they provide or the content they create.
