I'm told that it is considered good SEO practice to have multiple digital properties "around" a website. For example, Youtube, Flikr, Social Media pages etc.
Fine. I have linked my website to my G+ page, for example.
I'm about to upload an album to WordPress. The pictures exist on my G+ album. I was just going to download the pictures from G+ and them re-upload them to my WordPress Gallery.
Is there any SEO value in displaying the album directly from G+, rather than downloading and uploading to WordPress?
This is a specific example, but what about other digital assets like Youtube videos?
What's best practice here? Does this "branch" of SEO, if it exists, have a name?
