SEO or SEM? Which is suitable to your business strategy?

In some circumstances, SEM and SEO can be used interchangeably because of their similar set of activities. Although it might be difficult for people who are not in the marketing industry to notice the differences, a solid understanding about these two terms is necessary to help you create a clear and effective marketing strategy for your online visibility.


This article will go through the most basic differences between these two marketing tools.


What is Search Engine Optimisation?


Search Engine Optimisation, a.k.a SEO is an approach to optimise a website in order to place a high rank in Search Engine Result Pages (SERPs), so as to get more organic traffic.


SEO is an important marketing tactic in digital marketing strategy because of its exceptional benefits. Firstly, SEO helps a business increase organic traffic. By being on the first page in SERPs, there is a higher chance that users click to your website. Secondly, SEO improves authenticity and trust. When people do search, if your website is in a high rank position, this means your website is relevant and authentic. Users are more likely to trust search engine’s suggestions. Last but not least, SEO increases conversions and improves conversions rate. If your website is on the first page, when people make a search, there is a high possibility to convert. This is because your page is quite related to the user's search intention. In other words, your website is the solution that the users are looking for.

SEO is a complicated process which requires a lot of work. These are a number of tasks you need to perform when trying to improve SEO for your website. They are classified into 2 tiers:


On-page SEO


On-page SEO is a series of practices that you make adjustments on an individual page and the website as a whole. It can be to optimise website structure, so as Google can read through and users can navigate your website easily. On-page SEO isn’t only about optimising content on body text, it also includes adding keywords into textual elements on the website. These elements are URL, title, meta description, alt of images, ect. They help users and search engines understand the content quickly.


Another consideration of on-page SEO is to optimise technical aspects on the website. They can be using structured data, reducing page load time, improving user interface, ect. Therefore, technical SEO requires you to have some understanding about web design and coding.


Off-page SEO


Off-page SEO is the activities that happen out of the website, which is mostly known as backlink building.


Backlinks (or external links) are the links that point from other pages to your website. Backlink building is the practice to increase the link popularity. When you have many quality backlinks, your website is seen as authority and trusted by search engines. Then, your website is more likely to be suggested to users.

What is Search Engines Marketing?


Search Engines Marketing, a.k.a search engine paid ads, is an approach to get traffic by purchasing paid or sponsored ad listing on search engines.

Purchasing ad listings is beneficial since it ensures you are in front of your potential customers and appear when people are looking for the products or services you offer. In addition, search engines are mostly used for searching information and they contribute significantly in customer purchase behaviours.
