Backlinks are the backbone of any website. Google keeps on updating its SEO algorithm periodically. Artificial Intelligence is also conquering internet now. So, if you try to cheat Google, you will be definitely penalized soon. So, you have to follow google guidelines when working with SEO.
If you are building backlinks manually, it will help you to get high quality visitors from backlinking domains and also your site will rank in SEO. Even though backlinks alone can’t help to rank high in Google, we need to properly build backlinks from trusted sites.
Instead of that, if you buy SEO services online, there are high chances to get bad backlinks that may decrease your site’s credibility. All SEO services promise that they would provide high quality backlinks but most of them are using software to build backlinks. And also, they will use irrelevant domains to link which can be easily identified by Google as spam. Those backlinks will not be useful at all. So, if you are aware of what they are doing, you can go ahead if not stay away from them and start building quality backlinks on your own.
It is unsafe to buy backlinks from unknown SEO services. If you are 100% sure that they build backlinks manually from relevant domains, you can buy it without any doubt. Google will like it too. On the other hand, if the backlinks are built from irrelevant domains using software, your website ranking will decrease for sure and all your hard work will be wasted. So, think twice and act.
