# Recipes for Search Engine Optimization using Polyglot

If you have installed the `jekyll-polyglot` gem, these additions to your site header can easily provide your jekyll blog with Google-powered SEO bonuses.

## HTML Language Declaration

Per W3C Internationalization Best Practices you can set the default language of every page with a meta tag. Just add the following to your header:

    <meta http-equiv="Content-Language" content="{{site.active_lang}}">

## Multi-language SEO using hreflang alternate tags

You can easily add hreflang alternate tags to your site, achieving SEO with google multi-language searches. Add the following to your header:

    <link rel="alternate"
          hreflang="{{site.default_lang}}"
          href="http://yoursite.com{{page.permalink}}" />
    {% for lang in site.languages %}
    {% if lang == site.default_lang %}
      {% continue %}
    {% endif %}
    <link rel="alternate"
        hreflang="{{lang}}"
        href="http://yoursite.com/{{lang}}{{page.permalink}}" />
    {% endfor %}

## All of the above

You can get all of the above with a single tag added to your `header.html`:

    {% I18n_Headers https://untra.github.com/polyglot %}

Just add the permanent url for your website and all of the above SEO will be added to each page in your website. In version >= 1.2.4, you can leave it empty, just calling

    {% I18n_Headers %}

and it will default to your `site.url`

With this SEO, each page click for one sites language will count towards the net clicks of all languages on the website.
