The keywords are an important part of linking pages to other pages about the same subjects. The list ‘related’ on the right side of the website is based on the usage of keywords. So the more you use appropriate keywords the more relevant the list ‘related’ can become for visitors.
We have around 150 keywords, some used more than others and others are maybe not so relevant at this moment, but never delete a keyword. Whenever you delete a keyword, you delete many links between different pages. If you are somehow wondering about why a keyword is existing, look at the website what is linked to it and talk to the communication manager about the option to transform it into a tag.
Tags form a smaller network on the website. We have thousands of tags, so linking them is not going to create a precize network, they are relevant as a specification of the bigger subject. Thus, you should always use at least one keyword (preferably more!) and you can use the tags as support for the keywords.
For what sort of page do I use a keyword/tag?
For every sort of page!
Pictures: use the same keywords and tags the page it appears in. If the page doesn’t have any, then you check for relevant keywords for the page.
Article: check which keywords and tags are used for the collaborating program and feel free to use other keywords that are applicable for your article.
New Program: check with the program manager what it is about and go through all of the keywords to make sure you have all the relevant ones.
Here you have an overview of the keywords we have. Use it to see what the different programs have and update it whenever you add one to a program.
