Search Engine Optimization

Everyone wants their website to be well visited. A position at the top of the search results in search engines like Google helps. Search engine optimisation (SEO) helps with that.

Search engine optimisation (SEO) is used to achieve a higher position in the results. How well is your website found?

Make it easier for search engines to index your website by using search engine optimisation:

Search Engine Optimization (SEO) using friendly URLs

On a website, each page has its own URL. A good URL is readable, hierarchical structured but as short as possible, and gives much information about the page. A good URL gives visitors a good idea of ​​the information that they will find on the page before they click it. Search engines use the URLs for indexing: the keywords are indexed. The less "slashes" in the URL, the closer to the home page gives an indication how important the page is for the site.


For visitors is an HTML sitemap a useful tool to see the structure of the website at a glance, and without having to navigate many clicks to deep pages. The same applies for search engines that you can server an XML sitemap. Normally, search engines index pages of a website. They go through a page and visit each link is listed on that page. Through an XML sitemap the search engine understands the structure at once, including information about how often a page is updated which might use the search engine to determine how often it should come by to index.


A breadcrumb trail shows the hierarchical route of the home page to the page where the visitor is located. This is useful because if a visitor arrives at the website from a search engine, the navigation path then displays information about where the visitor is in the site. It offers the visitor to navigate an additional option. For search engines are handy crumb trails: crumb trails contain keywords, giving the structure of the website and can be displayed by search engines in the search results.

Semantic HTML

A web page that is built with semantic HTML displays in the HTML structure information about the importance of text on that page. An H1 headline will be more important than an H2 header. And an H1 headline will provide explicit information on the subject of the page, the text between <p> paragraph tags </ p> that follows. Search engines use it to determine context and significance of texts. Make sure the pages are structured semantically.

Structured Data Markup

For several years Structured Data Markup has been used within a web page to determine the context of texts.

Rich Snippets

A search engine like Google displays search results in the increasingly context-based information about the search results. Think of ratings (the rating asterisks), information about video, audio clips and authors.


Microdata is an HTML specification to give using metadata (information about chunks of information) of the content on web pages context. As written on a website ratatouille, you can give context by microdata: Ratatouille is about the film Ratatouille (2007) or the French court Ratatouille?

The Microdata can only be understood properly if everyone uses the same context diagrams. provides a collection of shared markup types that are used by search engines.

External variables

There are many variables that determine your position in the search results in, for example, Google:

  • The search history of a Google logged in internet user
  • The search history of a non-Google logged in internet user, e.g. based on IP address
  • The location of the user
  • The device (desktop computer or mobile phone) the user is using to search

With a search engine like DuckDuckGo in combination with incognito mode or another browser, you can disable many of these variables when searching for your own website.
