I have about 8 main sites that feed traffic and a handful of lesser performing ones that occasionally make page 1 SERP. And maybe ten more that I have never developed much. Plus dozens of parked domains. I have thought of taking, say, 4 of those main eight and really making them better and stronger so that they more often reach page 1 SERP. This way, I would dominate better.
I also want to make my #1 site even better and stronger with a complete redesign and link-building.
Any suggestions on what I could have these friends who owe me do on a daily basis? What exactly could I have them do? They are willing to "pay me back" with labor. How much to "charge" their "balance due?" They could work say, 1 hour per day.
