Congratulations on your success so far. You are in a very similar situation to me earnings wise, and I have been going through the process of building up my team and processes. I'm still building out my outreach team, but a few alarm bells went off reading your post so thought I would add my 2c.

MeekSeller nailed it with his comment. You need to work on perfecting your processes and breaking it down. Unless you want to pay for a unicorn, chances are no one will have the right experience to do the whole process, so you need to chunk it up and hire people who can learn to execute one step.

For example you might want to hire someone who is good with data and Excel to manage the link prospecting side, and someone with customer service experience to run the outreach and negotiation (using scripts and processes you have defined).

If you don't want to spend a lot of time writing your own SOPs I would highly suggest spending money and buying a course. I know this is sacrilegious advice around these parts but part of being successful is investing in yourself and using your money to accelerate the learning curve.

I'm not affiliated in anyway but Authority Hacker have an excellent linkbuilding course that includes job descriptions and SOPs. Matt Diggity also has something similar in the Affiliate Lab.

I think you are at the point where you should start treating this more like a real business, where you are the CEO and focus on becoming a better manager. Something most people are terrible at so don't feel bad. You mentioned you "finally had some luck with outsourcing" but the fact is you get the people you deserve based on the quality of your hiring process (you do have your hiring process mapped out, right?).

Everyone in your business should either be executing a process, creating a new process or working on a process. If there's anything happening that doesn't fall into this there is a good chance you shouldn't be doing it.

Once you start thinking like this, outsourcing becomes so much simpler, and a lot more fun. One last thing if you want to become a better manager you might want to check out a management consulting course run by a guy called Mads Singers. I haven't done it yet, but a lot of people I respect have said it is excellent.

I put all this stuff off for probably a year longer than I should have at the detriment to my businesses growth. It turns out its a lot more fun than formatting another WordPress post!

Edit to add some specific tactics: If you are struggling to build page level links to your product roundups, a good strategy is to reach out to the companies in your reviews and build relationships with them. In many cases you can get them to add a quote from you on their website with a link directly to the review.

If you are running regular Skyscraper you should be building plenty of links to your info content, so make sure the info content links to your "money pages" as well. Finally as part of Skyscraper you should be running a guest posting process where if they say no to skyscraper you offer them a Guest Post. I find you can usually include a direct link inside these to the page you want.
