What is On-page SEO?

On-page SEO is the practice of optimizing your website contents, structure, design, navigation, and other elements to make your site more visible and attractive to search engines. Simply put, everything you do on your website to improve its ranking in search engine results pages (SERPs) is considered on-page SEO.

On-page SEO Factors

There are many factors that influence on-page SEO, but some of the most important ones include:


The most important on-page SEO factor is choosing the right keywords. These are the terms and phrases people use when searching for products or services like yours.

Using the right keywords in your titles, headings, and throughout your content is crucial for on-page SEO. Not only do you need to use the right keywords, but you also need to use them in the right places and in the proper proportions.

Title Tags

Your title tag is the text that appears in the search engine results pages (SERPs) when your website comes up for a particular keyword. A good title tag should be accurate, relevant, compelling, and short.

Content Quality

The quality of your content is also essential for on-page SEO. Your content should be well-written, well-structured, informative, and relevant to your audience. It should also contain your targetted keywords but in a way that sounds natural and not forced.

Internal Linking

Internal linking is the process of linking to other pages on your website from within your content. It helps search engines understand your website structure and find new pages more efficiently. It also helps improve the user experience by making it easier for visitors to navigate your site.

Mobile Friendliness

As most people nowadays use smartphone devices to browse the internet, it has become a significant search engine ranking factor. Therefore, your website should be designed to be responsive to different screen sizes and easy to use on mobile devices.

Alt text for Images

If you have images on your website, it is important to add alt text to them. This is because the alt text helps search engines understand what the image is about. It also helps visually impaired visitors who use screen readers to browse the web.

Core Web Vitals

Core Web Vitals are a set of metrics that measure your website’s performance and user experience. They include things like page load time, interactivity, and visual stability.

Improving your Core Web Vitals will not only improve your on-page SEO but also result in a better overall user experience for your visitors.

Page Schema

Schema markup is code (semantic vocabulary) that you add to your website to help search engines better understand your content. Using schema makes search engine crawlers understand your content and index it accordingly.

Off-Page SEO

Off-page SEO is the practice of optimizing your website for ranking factors that are not controlled by you. In other words, it is everything you do outside your website to improve its position in SERPs.

Off-Page SEO Factors

Major off-page SEO ranking factors include:


A backlink is a link from another website to your website. Backlinks are the most critical elements for off-page SEO because they show search engines that other websites are linking to your site, which means your site must be of high quality and trustable.

Domain Authority (DA)

Domain Authority is a metric created by Moz that predicts the strength of a website and how well a website will rank in SERPs. It is based on factors like the quality and quantity of backlinks, the age of the domain, and other SEO ranking factors.

DA is an important off-page SEO factor because it shows search engines that your website is a reliable and authoritative source of information. However,  it is important to note that DA is not a direct ranking factor, and not all websites with a high DA will rank well in SERPs.

Is On-Page or Off-Page SEO More Important?

On-Page SEO is more important as it shows Google what your content is about. If you don’t have your on-site SEO in order, then you won’t rank. But without Off-Page SEO, it’ll be tough to rank for any competitive keywords because Off-Page SEO helps build your website’s authority. 

So, you will need to focus on both On-Page and Off-Page SEO with a bit more emphasis on the former. If you want your website to rank in Google, you need to make sure that each page on your site is optimized for the keywords you want to rank for.


At the end of the day, you need to concentrate on both On-Page and Off-Page SEO to see the best results. You can have the best On-Page SEO in the world, but if you don’t have any backlinks, it’s going to be hard to rank for any competitive keywords. Besides, you can have many high-quality backlinks, but they will not pay off if there is nothing good inside the website.

The best way to approach SEO is to consider it a long-term investment. The more time and effort you put into it, the better results you will see in the end. So, start working with the On-page SEO and gradually move to the Off-page SEO. You will see the results if you do it right.
