I'm wondering about duplicate content issues on social networks. Say you use a networking tool like SocialMarker and use the same description/title for every site. I'm thinking the real value of spreading these links is that you're putting links on all these sites - not necessarily in how those sites will be indexed in search engines. But...what's the damage for linking to a long list of social networks and not mixing up the description for each submission. Will duplicate short descriptions cause all the other submissions to be automatically ignored by Google, ala mass article directory duplicates?
You should be completely fine as long as you continute to build a large amount of links at a time. Since you have so many differnt links then it will be ok to link like that. It wont receive a duplicate content penalty because they are all linking back to an original source.
The duplicate content penalty is applied to the "content" or visible text on a page. Not the On-Page SEO Elements. It does not appear that it is triggered at the 'sentence' level but at the 'paragraph' level. But if you start duplicating the <title> and description, Google may see the sites as "affiliate" sites and PR0/GrayBar them.
You shouldn't submit to 100 social bookmarking sites with the exact same title and description. It's like directory submission - you have to rotate the title & description every now and then for better results.
Seems like the title wouldn't be as big of a deal because if a post was to go viral most other people would just use the post title to bookmark the site. Maybe just avoiding a description altogether makes sense, though obviously not ideal.
Depends on what the Search Engines choose to do with the duplicate content. If all your links are the same they may be able to filter them or penalize them. And if they do that are you going to go back to all those social network sites and remove or edit your links? Imagine how much time that would take even if you could do it? Google is the best at figuring these self generated linking schemes out. So you run a risk. But everything you do has risk, so figure out how important it is to save you time vs. taking the time to write unique descriptions. If you have 1,000's of links that are EXACTLY the same that would be pretty easy to filter.
I've been submitting the same exact piece of copy to tons of social bookmarking and other sites like article directories, squidoo, blah blah and everything is doing great. I have no problems using the same content more than once.
