Content created with scripts and programs, rather than by hand.
Some blog owners want to make their blog part of their social networking strategy. That is a laudable goal - but the blog has to have its own distinct content, as well.
Don't build your posts around automated content, such as feeds from other blogs and websites.
Feeds are good accessories - not good content sources.
Feeds from FaceBook, Instagram, Twitter, and other non Blogger content, can be used as blog decorations - and can be valuable, when added as decorations. When used to excess, your blog will look like another spam blog, being developed.
Newsfeeds, as blog content, make your blog just one more scraped content host.
Newsfeeds look just like more scraped or syndicated content, provided willingly or unwillingly. Even though a newsfeed is content provided willingly - and available for all to read - if you publish it as blog content, your blog is still just scraped content.
If your blog has only newsfeed provided content, it won't have unique, indexable content - and won't get any traffic from search engines, whether or not it gets classified as a spam host.
Embedding includes formatting that may cause problems.
Embedded posts, from FaceBook, will cause problems similar to posts composed using Microsoft Word. The meta code in the posts, when published in the posts newsfeed, will corrupt the feed - and will cause later problems with services like FeedBurner.
To use embedded content safely, reformat the posts.
- Edit your post, in Compose mode.
- Select the entire post.
- Hit the "Remove formatting" button, in the toolbar.
- Reformat everything, as desired.
- Finally, Save the reformatted post.
Spam blogs use embedding, feeds, and links, to increase their size.
Both direct links to other blogs and non Google websites, embedded posts, and feeds from other blogs and non Google websites, are part of any well designed spam blog farm. Don't make your blog look like a splog farm node - spend time publishing real content, for your readers to enjoy.
