When Google Publisher and Authorship tags are used correctly, they can be very helpful to overall search engine optimization and, most importantly, to searchers looking for your content. They can help your content stand out in search results, and studies have even shown that search results with authorship rich snippets can attract more clicks than search results without them (even higher ranking ones!), while publisher tags help Google see your Google plus profile and website together.
Unfortunately, they are not always used correctly. Each tag tells Google something different, so it is important to understand their differences and benefits, as well as place them on the right pages of any site.
