Assuming that you blogger is set-up (ready to bank) and all you need to make money is traffic:
- start posting on niche related blogs with useful comments and your link
- post on niche related forums, same as above
- post some videos related to your niche on youtube and promote your link there
- post comments on youtube videos that are related to your product/service
- post on social media platform if the niche is suitable. think twitter, reddit
- upvote your youtube/reddit comments to show-up higher

If done well you should get traffic in hours. If you don't, you either have to adjust comment/niche/platform.
Plenty of guides here to do all that, plus a ton of methods that still work.
Don't expect for any method to work flawless from first try. Test, adjust, test, adjust. Eventually you will profit.
