A: I recommend you focus first on these categories:

- Directory, Local, Review Sites, and Social
- then Deal & Coupon

These are the best link opportunities with the highest chance of being indexed.

About your question about not being indexed, I guess you check in Ahrefs?
It takes up to 30 days for these to appear, so you might as well need to wait a bit.

Aim to 10-20 links per month (not more than that, it's not a sprint, the goal is to have a consistent growth of referring domains and not one big spike and then a flat line).

When you're done with these easy opportunities, you should aim priority for the Level 5 & Level 6 opportunities.

In Level 1, the High DA Profile is the least powerful backlink and should be used as a last resort. The worse is Social Bookmarking, URL Shorteners, and Article Submission.

I need to write a Blog Post on how to take advantage of these categories. Still, in a nutshell, the strategy for these should be to submit low-quality articles to the "Article Submission" service (the article linking to your money site) and then try to do some social bookmarking to this post with URL Shortener to give some juice to these articles.

This is worth doing only if you have already exhausted all other options; I would only waste my time with that if I tried everything else first.
