When it comes to free backlinks, there are so many services out there that will do hundreds to millions of them for free. Just remember that with all free backlink services there is a price. Now you may not be paying with money for your backlinks, you could be entering your email to get the links or paying the ultimate price of decreased rankings...
In this discussion I will cover the good and bad things that could happen when using free backlink services.
Not all free backlink services are bad. In fact, I've found a few that actually did a pretty good job at what they were offering for free When you're getting a free backlink service I would never use it on your money website because it could be pretty bad. I would test it out on some random website you find online that has no SEO at all and see what the free service can do.
A long time ago there was a service that ran some type of internal software every time you entered your email. After you entered your email it would run the job and send you a report once it was finished. This was pretty amazing because it would allow me to set up new emails on my hosting to use in the service and get a new job done whenever I wanted it. After that I would just delete the email and be done with it lol.
But that's not where the free work comes into play. What I did was sold this as a service and had people pay me $10 or $20 in order to get some backlinks build within a day. The reports sent to me were super extensive and all I had to do was forward them to my clients I basically was acting as the middle man and I made a decent amount of money doing this. It was a sad day when the website closed it's doors and I had to start doing all the work myself lol.
Free Tier 2 and Tier 3 Links:
When you're using a free backlink service you will always want to aim them at your tier 2 and tier 3 links. This is because they will likely be low quality links and you don't want them aimed at your main pages. You're going to be doing something similar to this when you run your own tiered linking campaigns, so why now have a free service run it for you lol.
You could be killing your rankings by using these free backlink services if you're aiming them at your main pages. I would never recommend using any type of software to build backlinks and aim it at your money site because it usually ends in something bad.
Some of these free backlink services are set up by people who have no clue what they're doing and will only post to websites that auto approve your links. This usually gets you thousands of links from link farms, and that's never a good think to add to your backlink profile.
There's no way to initially tell if a free backlink service is going to be good or not. You will need to test them out and make sure that it's worth aiming at your own tier 2 and tier 3 links before you pull the trigger. If you find a good service that allows you to use the email trick I mentioned above, you can usually run it as a service and make a few bucks each month
