What makes a backlink bad??
- Thread starter drumltd
- Start date
Then the 'entertainment site' is part of the XXX link neighborhood.
Well the theory I have is as follows
I also treat follow and no-follow links as the same for this test.
I have run the test on 5 sites, and I broadly agree with the results, I'm not saying it won't give any false positives, and I'm not saying it will catch every bad link, but it gives a good starting point to manually check from, which is great when you have 10000s of links to check
Code:
If number of pages indexed in google < 20
Bad Link -> Catches Banned Domains, and small sites with no content.
Else If Domain is Less Than 1 Year Old
Bad Link -> Catches alot of socialbookmark\site info\copycat type sites, that are nothing more than link farms.
Else If Domain Authority is Less Than 10
Bad Link -> These sites tend to be just plain crappy
Else If The page has More than 75 OBL with Less than 50% of them going to our site.
Bad Link -> Site is probably a Spammy Link Magnet and if not Big G will probably think it is anyway.
Else If Anchor Text is used for > 25% of links
Bad Link
Else
Good LinkI also treat follow and no-follow links as the same for this test.

The bad links on high PR sites will still be penalized - think comment spam on .edu blogs. I've got no formula to quantify relevance at the moment, but my general sense is that you should stick to socials/bookmarks/2.0s/niche relevant blogs and forums. Maybe some high quality directories, etc. If you're selling baseball products, why link to a .edu blog post about a snow day in 2012 that has hundreds of other spammed links? Yes the root domain has high PR, but G is likely not looking at that link favorably (not just because of irrelevance but also high OBL, etc.)
Not sure about the extent to which one should analyze the inbound links. Similar to relevance, a general overview can be illuminating. Would be interested in hearing another (more fully elaborated) opinion on that matter as it's a good question drumltd

Add broken html to the list, bad neighborhood sites (if the site is on a shared host), inbound links to name a few.
