While you could theoretically add the necessary metadata tags yourself, Jekyll SEO Tag provides a battle-tested template of crowdsourced best-practices.
Jekyll SEO tag is designed to output machine-readable metadata for search engines and social networks to index and display. If you're looking for something to analyze your Jekyll site's structure and content (e.g., more traditional SEO optimization), take a look at [The Jekyll SEO Gem](https://github.com/pmarsceill/jekyll-seo-gem).
Jekyll SEO tag isn't designed to accommodate every possible use case. It should work for most site out of the box and without a laundry list of configuration options that serve only to confuse most users.
2. Add the following to your site's `_config.yml`:
```yml
gems:
- jekyll-seo-tag
```
3. Add the following right before `</head>` in your site's template(s):
```liquid
{% seo %}
```
## Usage
The SEO tag will respect any of the following if included in your site's `_config.yml` (and simply not include them if they're not defined):
*`title` - Your site's title (e.g., Ben's awesome site, The GitHub Blog, etc.)
*`description` - A short description (e.g., A blog dedicated to reviewing cat gifs)
*`url` - The full URL to your site. Note: `site.github.url` will be used by default.
*`twitter:username` - The site's Twitter handle. You'll want to describe it like so:
```yml
twitter:
username: benbalter
```
*`logo` - Relative URL to a site-wide logo (e.g., `assets/your-company-logo.png`)
*`social` - For [specifying social profiles](https://developers.google.com/structured-data/customize/social-profiles). The following properties are available:
