What are the differences between seo on page and seo off page?

Although they share the objective of improving web positioning, the On page SEO and the Off page SEO focus on different aspects. 

On page SEO is related to the actions you take within your website to improve its performance and visibility, while off page SEO focuses on external factors that increase the authority of your domain. 

Both are essential components of a comprehensive positioning strategy, but have distinctly different approaches. Below we will explain the key points of each discipline:

Seo on page

  • Optimise internal page elements.
  • It includes content, metadata, structure of URLs and loading speed.
  • It is entirely up to the site administrator.
  • Elements of on page SEO include actions such as content optimisation, use of internal links and improving the user experience.

Practical example of on page SEO:

An online shop optimises its product page by ensuring the following:

  • The title includes relevant keywords, such as "Sports T-shirts".
  • The images have descriptive alternative text, such as "blue sports jerseys".
  • The content provides detailed and unique descriptions.
  • Internal links take the user to other related categories.

Seo off page

  • It focuses on factors external to the site.
  • Includes backlinks, social mentions and domain authority.
  • It requires external partnerships and strategies.
  • External links, although part of the Off page SEOcomplement on-page SEO by increasing the relevance of internal content.

Practical example of off page SEO:

A company collaborates with an influential blog to publish an article related to its product, obtaining:

  • Quality backlinks to your homepage.
  • Social mentions on platforms such as Instagram and Twitter.
  • Increase in the domain authority thanks to external exposure.

Both strategies are complementary and necessary for a comprehensive SEO plan.
