You don't need to be a Google Engineer to know that. Google has been giving advices on what type of links you should and should not get.
google loves nature backlinks, but you can't wait those nature links so you have to build yourself backlinks, that 's all. In a word, you have to build yourself do follow backlinks.
You don't have to be a member of Google to see what is a good link. After you spend a couple of years looking at sites, their ranking, their PR and backlinks you start to see patterns and you can tell what kind of links make a difference and what links are worthless. Anyone can put links on most forums that makes them fairly worthless. The whole backlink value is a weight on what is informative and reputable. Anyone one with 30 min to spare running through a forum dropping links is not reputable it is just another poster in the sea of forum posters their is no way for google to tell if their info or link is worth anything of value.
Yes, you need unique articles. If you submit one article not more than 2-3 times there won't be any negative effect. But make different articles if you submit them on many websites. Why do I know it? I'm working at the top Russian SEO company (bdbd.ru). We promote more than 1000 websites at a time and have about 400 employees. Of course, we have to pursue regular researches to find the most effective ways of promoting websites. That's why we have much info about link building to analyze.
Where did you get that information? It's completely false. What you just said right there is that you either have to buy links or have multiple websites hosted from different IPs to put your links in the content without submitting articles. Google doesn't ignore any of the things you said it does. Sure, forum posts don't get as much weight as blog comments, and blog comments don't get as much weight as content links but that doesn't mean they're magically ignored. Get your facts straight.
What are you trying to say? Is your website not indexed with Google? If you are getting your website in SERP's then it is indexed and you dont have to submit it to Google. Try building as many back-links as you can. Use all of back-linking techniques.
I answered in my post http://forums.digitalpoint.com/showthread.php?t=1981442&p=15189988#post15189988 Unfortunately it is not false. There are a lot of free methods of getting incontent links posted by websites' owners. Such links much more effecitve than any kind of comments and links in user generated content.
T-34, I disagree with the last one link clone, as I submit unique articles but I use the same bio and alternate links and my sites are loved by Google.
it is well recogniged among the webmasters that forum signature and comments on dofollow blogs are an effective way of getting good page rank. Getting backlinks through these methods are really usefull. You should correct yurself brother
when people claim Google likes this and doesn't like this, it's all assumptions. technically all links are same
Here is a great resource from SEOMoz. I appreciate their research and testing. All Links are Not Created Equal: 10 Illustrations on Search Engines' Valuation of Links
Wow you must work for Google cause you know exactly what links they use! Google still use forum signatures and Blog comments. And all of your comments are just your opinion
press release links and manually created links are most useful for google. however,signature and forum post links are great help also
