SEO #43
Description
Add meta description for all pages
It requires an excerpt property in the page header, eg:
---
layout: default
lang: en
uid: index
excerpt: geOrchestra is a free, modular, interoperable & secure Spatial Data Infrastructure
---
Posts should also have their own meta description, but I'm not sure that https://github.com/georchestra/georchestra.github.io/blob/master/_includes/head.html#L7 allows it.
Add a "title" attribute to links
The keywords from the link titles are taken into account by search engines.
Add h1 h2 tags to homepage
Same as above
