I am a blogger and I have lots of micro niche sites, only a few are updated daily though. In each of my blog, I have widget that would show my other blogs. So that means, each blog has the link to my 6 other blogs. Is this a bad thing? How will it impact my sites? Is this considered link farming?
No I don't think 6 outbacklinks is considered link farm, link farms contains dozen of links, but I think that it's not wise to link all your blog to each other unless they are topic related.
whoa, that's too many bro. i'd suggest you to link one blog to just 1 other blog. if you link 1 blog to all 6 blog of yours, perhaps big G won't consider it as link farm but you can lose lots of link juice. remember, if you link to a web page, it means you vote for that page. and for each vote you make, you're losing link juice. in the end, link from your blog won't be too much of a high value
Or even better... Use a little phop and rotate maybe 2 links at a time so that they are randomly linking to each other whenever someone hits your blogs...
You are on the borderline of it being a link farm, you do not want googles backhand on your sites. I suggest lowering the number of blogs and rotate the blogs differently. Good Luck.
Having 6 links your site won't be considered by Google as a link farm. Moreover, I guess they are kept on one Google Analytics and Webmaster account so Google easily associates all of them with you (and doesn't pass any link juice from one site to another, by the way). However, you can do something just in case: add nofollow attribute if these links are side wide (appear on all site pages) or put them just one page ("About me", "My other interests" or something of that kind).
IF one article contains more then 10-20 links then i would be considered as a link farm . IF you put 6-10 links of your other blogs in footer of your main active blog then i don't think anyone would consider it as a link farm .
