Yola for example have an RSS chicklet available on any "blog" page and simply by clicking and dragging this chicklet onto your page, the RSS subscription button or chicklet is installed, configured and ready to go as soon as you re-publish (update) your site.
The chicklet supplied is a recommended standard RSS chicklet and is instantly recognisable. Fortunately the concentric three wave lines have been adopted by many RSS chicklet designers as the central theme for the myriad of cutomised icons out there, so in fact many are intuitively recognised despite colour and design.
There are some very artistic creations of RSS chicklets around the web and the creativity of their designers is amazing. For example:



To place any of these or others, you take note of the image file name and the folder(s) then drag an html widget into the place where you wish to place the chicklet. The next step is to add the code into the HTML widget:
<a href="full URL of your RSS feed" (eg:"http://ediblyasian.yolasite.com/recipes.rss")><img src="url of your RSS chicklet that you wish to embed"(eg:"http://ediblyasian.yolasite.com/resources/buttons/28.png" )title="{an optional title for the chicklet} " alt="(an alternative description of the chicklet in case the image doesn't show and great for SEO requirements)"eg:"RSS link dock recipes-rss" style='width:50px; border:none; align:left;'></a> {The 50 px statement here is the width of the display of your chicklet and may be adjusted to suit your page style}
Simplified:
<a href="full URL of your RSS page"><img src= "relative or full URL of the image of your RSS chicklet" title="{optional title of your chicklet}" alt="alternative decription of the image" style='width:nnpx; border:(style) align:(style;'></a>
Specific example:
<a href="http://ediblyasian.yolasite.com/recipes.rss"><img src="resources/buttons/28.png" title=" " alt="RSS link dock recipes-rss" style='width:50px; border:none; align:left;'></a>
