## Technical stuff

* Properly configured robots.txt
  * Don't disallow too much, only what would really drag down your ranking!
  > Example:
  > ```
  > User-agent: *
  > Disallow /admin
  > ```
* Well structured pages, e.g. put things in the correct places and use semantic elements where possible.
  * Headings
    * Use <h1> for the title of the content, not the name if the site
    * Only use <h1> once
    * For Sub-Headings use <h2> and smaller, depending on their "indentation" level
    * Don't abuse heading-tags for non-headings, use css instead
  * <title> for the title (displayed in the browsers titlebar)
  * <article> for main content
  * <header> and <footer> for the respective header and footer
* Add meta data
  * Default meta-properties
  * open graph properties
* Responsiveness (mobile friendliness)
* Follow best practices from Google Pageinsights / Lighthouse-Tab in Chrome developer tools
* have a favicon, preferably with `.ico` ending and format (.ico is a multi-dimension file format)

## Content related

* Keep users on the page for long (WRITE GOOD CONTENT!)
* Links to know sites and link-backs from known sites

## Unsure whether these are helpful and how helpful:

* Add a sitemap.xml (referenced in robots.txt)
