Hi there
As said previously SS is a framework that mostly focuses on Developers. As such, I found that when I started on SS I was coding much of the code myself for various reasons.
A 'quick fix' for Google Analytics for example, was for me to add the following into Page.php in the init() function:
Requirements::customScript(<<<JS
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-XXX', 'auto');
ga('send', 'pageview');
JS
);
As I got to know SS I started getting comfortable with the idea of installing modules. Now there are some of them I cannot live without.
For search engine optimization, and for a clean install of SS, these are the modules that I almost always include:
Google Site Maps (https://github.com/silverstripe-labs/silverstripe-googlesitemaps)
Silver Stripe Recaptcha (https://github.com/chillu/silverstripe-recaptcha)
and Silver Stripe Google Analytics (https://github.com/silverstripe-labs/silverstripe-googleanalytics)
There are many more modules available, and you will find that once you understand the framework, is easy to install (and if really needed, modify) the modules.
Regards
