I run five different adult blogs, each one is a different niche, so for example, jocks on one hairy guys one another, that sort of thing. I write original content for each post and don't get into any hinky stuff like a lot of my brothers in this field do.
Three years ago, I decided it made sense to put the graphics (collage of pictures) on one blog, centralize them so I could use them on whatever blog I wanted without having to upload them multiple times.
So all my graphics sit on Joe Blog, let's say, I might do a post on Joe Blog and use those images, but I may not do a post on Joe Blog but do a post on ABC Blog instead and pull the images in from Joe Blog. Sometimes, where appropriate, I might do a post on Joe Blog and ABC Blog, or on ABC Blog and XYZ Blog, and pull in the same images from Joe Blog to each of the others and write fresh text for each post.
I have taken a bit of a hit since the last Penguin, not massive, but enough that I noticed. So I'm looking at a bunch of different things.
I'm wondering if centralizing the images this way and using them on different blogs is potentially causing me any problems. Or it doesn't matter, they're just images?
For clarification, the purpose in running multiple blogs wasn't to create complicated linking schemes to game the SERPS. In my field it makes very good sense to have very niche-targeted properties because surfers who are into one thing might not be into another. Sometimes there's some cross over and that's when I'd do two posts on two different blogs.
