What is the Difference Between Onsite and Offsite SEO? | Aware Digital

If you’ve ever looked into search engine optimisation, you’ve probably heard people talking about onsite and offsite SEO strategies. Both are critical components of any successful SEO campaign – but what do these terms actually mean? What’s the difference between onsite and offsite SEO – and is one more important than the other?

Read on as we reveal all and show you how to get the most from your SEO efforts…

What is onsite and offsite SEO?

It’s no secret that SEO is important for being visible to your target audience and driving lots of targeted traffic to your website.

While SEO can be a complicated subject (and quite honestly the goalposts change on an almost daily basis), knowing even just the basics can really help you rise above your competitors.

One of the key things to understand is that SEO can be broadly split into two main categories:

Onsite and Offsite SEO. 

Both are equally important and work together to improve your rankings in search engine results, so let’s talk a little more about each and what it means in practical terms.

Onsite SEO

As the name suggests, onsite SEO (sometimes also called on-page SEO) is concerned with optimising the pages on your website itself to make them search engine friendly.

This is the easier of the two to get your head around because it covers all the things you have full control over – like creating relevant header titles and filling your site with high-quality, keyword-optimised content.

Onsite SEO is incredibly important because it helps search engines to more easily index each page on your site and understand exactly what the content is all about. This is also important for the user as it helps them see whether the page contains what they are looking for.

Remember: When someone makes a search, it is the job of the search engine to show the user the most relevant content possible. Onsite SEO helps the search engine understand what is on the page and serve up the highest quality, most relevant results possible.

What are the most important onsite SEO elements?

Search engines assess a myriad of different factors to determine where a page should rank within search results, including title tags, keywords, content quality, page loading speed, accessibility and much more.

Page title and meta description

The page title and meta description is what appears within search results, so it’s important to get this right and ensure that it gives the search engines (and the user) a clear idea of what the page is about.

Title tags should be limited to 60 characters or less and contain your targeted keywords.

Although meta descriptions do not directly affect rankings and search engines do not use them in their ranking algorithms, they remain an important part of onsite SEO. Generally speaking, they should be 160 characters or less and sufficiently descriptive to give a good idea as to what is on the page. Good meta descriptions encourage higher click-through rates, which in turn can also have a positive impact on ranking.

Header tags

Again, header tags aren’t as critically important to rankings as they used to be – but they remain an important part of basic SEO. They are vital for making your content easy to read and providing context for search engines.

  • H1 tags: Essentially the title of the page, the H1 tag introduces your content and incorporates the main keyword.
  • H2 tags: The main subheadings of your content, helping to organise your content into logical sections. If the H1 tag is the book title, H2 headers act as the different chapters.
  • H3 tags: A subsection underneath the main subheadings, H3 headers define the sub-headings and further clarify your content.
  • H4, H5 and H6 tags: These tags help to organise the page content even more and further break up the text.

Content quality

One of the biggest things search engines take into account is the quality of your content. Gone are the days when keyword stuffing and other decidedly old-school tactics would help you reach the top of Google. Today, search engines only want pages that contain high-quality content that is useful to people.

What IS high quality content? 

While there are no specific rules, you should generally aim for at least 500 words of useful and relevant content crafted around your keywords. Remember to make your content unique to each page and avoid the temptation of including too many keywords. In short, you should write for humans first and search engines second.

URL structure

Page URLs should be well formatted and contain keywords where possible.

e.g. /what-is-the-difference-between-onsite-and-offsite-seo/

Alt text

Each image on your site should have alt text attached to it. This is the text that is shown when an image cannot be rendered, and it is also extremely important in terms of accessibility as it is used by screen readers.

From an SEO standpoint, alt text can contain keywords and is another way to help search engines understand the content contained on the page.

Anchor text

Anchor text is the clickable text of a hyperlink. For example, here’s another post with more top SEO tips for eCommerce.

Anchor text helps search engines index pages and understand what content is about, so be sure that the anchor text is relevant to the page you are linking to. Again there’s no hard rules, but a guideline is to have 1-3 internal links on each page to relevant content.

Schema markup

In short, schema markup is code that helps improve how search engines read and represent a page within search results.

Adding this markup helps Google to understand a page’s content, and it can also be used to enable special features within SERPs – for example, recipe snippets that appear above the main results, with a video and star rating. You can find more information about structured data here.

User experience

Providing a great user experience is an increasingly important part of onsite SEO. 

What does mean in practice?

To start with, it’s about having a website that is quick to load (page loading speed), mobile-friendly and incorporates accessibility feature.

Again, it all goes back to how it is the job of the search engine to provide the user with the highest quality results possible.

Offsite SEO

Offsite SEO is all about the activities you do outside of your website. The main goal is to boost the search engine’s view of a site’s popularity, trustworthiness and authority, which can be achieved by generating backlinks or promotions from other relevant, high authority sources.

The number of links you have and, most importantly, where they come from, can have a huge impact on your rankings. Ideally, backlinks should be from highly trusted sources with a good Domain Authority. Imagine getting a backlink from the BBC or a leading university… That would immediately send a positive signal to Google, whereas a link from a spammy site would have the opposite impact.

Search engines take into account many different factors, including:

  • Site popularity
  • How relevant the linking site is
  • How trustworthy the site is – and what domain authority it has
  • Anchor text
  • When the content was published

Offsite SEO backlinks

Backlinks can broadly split into three main categories:

  1. Natural links: Links that are generated naturally – e.g. a fashion blog rounds up the top 10 tops for Summer 2021 and includes one of your products, with a link to your website.
  2. Manually built links: gained through link building activities, like asking a social media influencer to link to your content.
  3. Self-created links: Links that are created manually by yourself – e.g. adding your link to an online directory or posting it on a forum. Search engines often mark these links as spam, so you have to be really careful in this area.

In short, link quality is WAY more important than link quantity. A focus on creating quality shareable content is really the way to go, for example by creating regular blog posts that people want to link to and then promoting them on social media to encourage shares. Guest posting can also be a great strategy for generating backlinks and generally getting the word out there.

Onsite and Offsite SEO: Which is more important?

Now that we’ve discussed the difference between onsite and offsite SEO, you’re probably wondering about which one you should focus on.

The simple answer is that they are both extremely important. If you want to increase your rankings, you’ll need to develop a balanced long-term strategy that incorporates both on-page and off-page SEO techniques.
