资源说明：Sitemaps, Canonical URLS, and other important SEO bits
Installing
==========
script/plugin install git://github.com/peteonrails/seo-kit.git
script/generate seo_kit
What you get
============
Canonical link tag helpers
--------------------------
This is handy if you're using friendly_id or you have more than one way
to see an instance of a particular model. Setting a canonical URL of the URL generated by the path helpers
will ensure that search engines recognize the duplicate content and do not split page rank.
In your controllers:
def show
@user = User.find(params[:id])
canonical_url @user
end
In your views:
<%= canonical_link_tag %>
OR
= canonical_link_tag
If you have app/views/layouts/application.html.haml and a "=yield :head"" call set up,
then this is set up for you by default.
Sitemap Generators
------------------
The route /sitemap.xml will produce a valid sitemap for you. To
update which models are included in the sitemap, see
config/initializers/seo.rb
Add downcased model names to the SITEMAP_MODELS array to include more models. The kit
ships with the user model set up for sitemapping (which is a bad idea if you do not have
public profiles for your users):
SITEMAP_MODELS = %w(user)
If you have a blog site, then do this:
SITEMAP_MODELS = %w(post comment category user)
To include named routes or other URLs that we can't use generators (e.g. pages
controlled by high\_voltage), you can list them in the SITEMAP_URLS field. For example:
SITEMAP_URLS = [
"http://mysite.org/faq.html",
"http://mysite.org/about.html",
"http://mysite.org/privacy.html"
]
Notes
-----
I strongly recommend that you also install the "friendly_id" plugin and use it to generate
well-named links for your important models. Be sure to set canonical_urls on the show action
in your controllers for these objects, since they will be addressable in two ways:
http://host/users/1
http://host/users/fasteragile
You want the canonical_url to be http://host/users/fasteragile
