Should I buy Paid Links ?

In general it is not a good idea to buy paid links. Google always say that they penalise sites where paid links are a frequent occurrence. However the question is how does Google know that your link is a paid link in the first instance.

My advice would be to purchase paid links only where the sites that you are purchasing them from limit the number of paid links.

Avoid spam sites where their soul existence is to sell huge numbers of paid links.

All depends on what site you are buying your links from. I think this would be better to search a site and make a deal with the webmaster to have your link on their page, instead of buying links from a site that is only selling links.

It's interesting to note the subtle difference between paying for an ad on a website which is seen as okay and paying for a link, which in both cases can get the job done! In some cases you can also pay to have your article posted or better yet for free... So maybe the ad route could be another option?

Regardless of what you do - make sure that you have the website details upfront and you examine its authority and trust metrics... Also check how spammy it is.... and remember that there are a lot of sites which show fake PR (I've seen one page sites that claim to be PR5 lol) - so don't just rely on that!

If it passes all of that then it might be worth it... Especially if it is a high ranking, authoritative site, which will give a boost...

But as always you need to be careful... and definitely I would stay away from cheap deals on fiverr (almost all are fake PR) and sites that are obvious that the only purpose is to sell links...

My opinion the best way is to reach out and provide a great guest article...
