Is it better to buy PLR or create my own content?

It fully depends on your needs, as both ways have their pros and cons.

Creating your own content ensures complete originality, however it can be very costly and time consuming, especially in the beginning.

PLR, on the other hand, can save time and provide a great foundation to which you can simply add your own insights and views, thus making the content unique. However, without making proper modifications, you will simply blend in to the mass and won’t be able to stand out.
