This is a snippet of code taken from a Wordpress site using the famous (not so sure) Yoast WordPress SEO plugin v22.214.171.124.
Besides the plugin, the site has some really good information about in page/site SEO regarding wordpress, but it can also be applied to other types of web software, like wikis.
Placed the snippet here because I was thinking it would be really good if we had an automatic page keywords finder AND automatic description generator.
For the automatic description generator, if you use the technic of writing posts making a punchy affirmation first and then explaining it, it gets really easy to get a description variable filled on the advent that you have not wrote a description yourself for the page.
Here is the snippet:
