I am working on a rails app which is deployed on heroku. I have placed a meta tag within the head tag in my application.html.erb file but it hasn't changed on Google yet. I have waited over 5 days. Google is still showing text taken from my homepage.
There are also two other meta tags which seem to be auto-generated as seen in the page source excerpt below (i.e. csrf-param and csrf-token). Do these affect the meta description on Google.
Below are excerpts of the relevant files:
Excerpt of tag in application.html.erb:
<title><%= full_title(yield(:title)) %></title>
<%= stylesheet_link_tag "application", media: "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
<%= render 'layouts/shim' %>
<meta name="App Name" content="App description.">
Excerpt of sitemap.xml
<lastmod>2013-08-12T18:29:06+00:00</lastmod>
<changefreq>daily</changefreq>
Excerpt of page source on Google Chrome:
<html>
<head>
<title>App Name</title>
<link href="/assets/application-f915aa342a5dbd5b43771fda8cc.css" media="all" rel="stylesheet" type="text/css" />
<script src="/assets/application-6f2b9741258790f721edcb490ef.js" type="text/javascript"></script>
<meta content="authenticity_token" name="csrf-param" />
<meta content="DCzmx+4h+r3wNv5sMTwS7U5X7u/RizzttU4U9+23DgY=" name="csrf-token" />
<!--[if lt IE 9]>
<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
<meta name="App Name" content="App description.">
</head>
Use
<meta name="Description" content="App description.">
Instead of "App Name"
Google will index the "Description" meta tag:
