When it comes to getting your website found online, there are two very important sides to search engine optimisation (SEO) that you need to ensure are working together to complement one another: on page SEO and off page SEO.

In this article, you will learn some important SEO techniques on page and get the answers to your questions:

  • What is on-page optimisation in SEO
  • Why on-page SEO is important
  • How to do on page optimisation in SEO

We’re also including a quick on page SEO checklist to enable you to quickly go through your content to ensure your on-page content is performing at its best.

What is on-page SEO Optimisation?

On page SEO, also known as on-site SEO, is a method of content creation that optimises your website, your digital marketing, and your content marketing to be search engine friendly.

Ensuring your website is search engine friendly isn’t a simple task, and over the last few years, Google has really improved its methods of ranking web pages by usefulness. It’s important to follow the advice of both Google and SEO professionals and tick all of the boxes as it were, you’ll have more chance of your website and your business getting to the top of the search engine results page (SERP) and attracting more traffic.

As a side note, with Google being the biggest search engine on the internet, most guides (like ours) will focus on optimising your content for Google, but any optimisation you do will usually improve your rankings on other search engines like Bing and Duck Duck Go too.

Why On-page SEO Optimisation is Important

SEO optimisation, in general, is important for your website to attract traffic. With increased traffic should come increased conversions, whether you measure that in ad revenue, affiliate link clicks, sales, sign-ups, customers, etc.

The issue is increased low-value traffic is just not very helpful. When you improve on page SEO, you will be ensuring your traffic increase is from people who are specifically interested in your website and your content, leading to higher conversions.

Increasing your SEO on page optimisation with these SEO tips will strengthen your off-page optimisation and help Google to know exactly what your website is about, what your business does, and what type of users to send to it.

Google’s main aim when it comes to search results is to be helpful for their users. If you can make it easier for Google to know that your website is effective, authoritative, and trustworthy (Google’s handy acronym EAT), the algorithm will look upon you more favourably and your website will increase in rankings.

Of course, it’s not all on-page SEO that does this, but improving your on page SEO best practices will help to strengthen your off-page efforts, so it’s worth doing.

How to Implement on-page SEO?

There are a number of important on page SEO factors to consider, but it’s important to know that improving just a few elements of on page SEO won’t make a huge difference, but making a concerted effort to optimise all of your content will ensure you are hitting the important ranking factor.

SEO is a marathon, not a sprint, and it can take a while to see the results, but if you get into the habit of creating optimised content from that start and using these on page SEO tips, it will mean you’re always be starting off on the right foot.

The On-Page SEO Checklist

1.    Keywords – front load, density, long tail

Keyword research is still really important in 2020, and we do need to make the distinction between keyword stuffing and keyword use. If your keyword is “stained glass windows”, for example, you’ll want to use the keyword a few times in your content but not too much.

There isn’t really a set amount, but a good estimate is about 1-2% keyword density, around once or twice per 100 words, as long as it feels natural.

2.    URL Optimisation

URL optimisation gets missed out of a lot of lists, but it’s an important factor. Often, site builders like WordPress will assign a seemingly random name to your latest post, and it may look something like this:

your-site.com/287402

That doesn’t explain to your users or to Google what the page is. Optimisation is done best by being descriptive, not using capitals, and putting your blog posts into categories. An optimised URL for your post named “My Awesome Post” might look something like this:

your-site.com/category/my-awesome-post

3.    Meta Data

Meta Data is split into Title and Description. Both will appear on the SERP and need to be optimised. Your Meta Title needs to be under 60 characters, and your description under 160 characters.

For example:

Title: My Awesome Blog Post │Your-Site

Description: Need to find out about an awesome new idea? Check out this awesome blog post and learn more about awesome posts today.

4.    Tags

Back in the day when websites were hand-coded in HTML (before the mass adoption of site builders like WordPress, Shopify, Wix, etc.), titles would need to be wrapped in <h> tags. Today this is usually done automatically by WordPress or all other mainstream website builders, but it’s important to check.

Your content should look like this:

<h1>Post or Page Title</h1>

<h2>Content Subheading</h2>

<h3>Smaller Subheading</h3>

5.    Internal Linking

Internal links, links to another relevant page on your site within your content, is really important for two reasons, it shows Google that your whole website is focussed within your niche, and it allows your users to move around your website getting the information they need in addition to their original search intent (decreasing your bounce rate).

6.    External Linking

External linking is sometimes a bit of a controversial part of technical SEO on-page optimisation, it’s important to do, but you must look at the sites you’re linking to. It’s better to link to more authoritative sites, or scholarly sites, to boost your credibility.

In short, if you can find an authoritative site like Oxford University or a white paper on your topic that supports your content, link to it rather than something with no authority like an unknown blog.

7.    Image Optimisation

Image optimisation is important for both Google and for your website’s accessibility. Use the ALT section, optimise the size for better load time (usually a maximum of 1000 pixels), put your images in the right places, and make sure they are relevant. You also need to make sure there are more unique images rather than stock or free stock images and add a caption if it’s relevant.
