Using the software for link building can lead to sanctions of search engines, which will regard your actions as an attempt to manipulate rankings in the search.
If you can get a link from software, it's useless. Real links come from people, not tools. You need to make something worth linking to (high-quality tools, content, or graphics) and find people who have linked to similar content. Then pitch them your content and ask for a share. To answer your question, Google could penalize your site and you'll get less traffic because of shady links. Even if that doesn't happen, they won't help much.
Those tons of links coming from the link building software is obviously low quality sites in which they are easily vanish in short time period and the worst is telling Google that your site is manipulating the rankings.
Google don't like the link building software, they think the content of the link isn't good for reader, customer. Please make link by yourself, it is slow, but is good for your site.
automation and manual backlinking both have advantage and disadvantage many argue that software automation can harm your site, YES it can but for as long as you know what you are doing and you are doing it carefully and properly and have a good plan it will save you huge time and money. There are a lot of softwares out there that claim automation but not all is perfect it really depends on what you want to achieve just dont use it to spam. Automation have helped us with our clients but it really depends on your goal. Manual backlinking is also bad if you just use it to spam blog comments, use your time and energy on doing manual backlinks on contextual backlinking forums can help you as well see those signatures it can help you but use your signature and anchor wisely otherwise you'll end up the same.
We should considered something when we get a links, such as page authority, niche, domain authority, outgoing links from the page and more. But when the software is automatically generate links, that will spoil your website.
