You want both, but don't obsess over it. T2 and T3 will do a great job on getting T1 indexed. (can't believe you have a T4 but that's cool).
Indexing is important, but building new sites and tiers will get you in the money quicker. Save the indexing for when you are completely bored and want to do something useful. I do it every 2-4 weeks.
Oh happy happy joy
Now seo indexer is on every tier, not one central on off point ffs
Back to editing 60 tiers, one at a time
Two places its shown
Under main options and each tier
(insert expletive of choice here) happy happy joy
Finished my 1am maintenance at 2am
With seo indexer off, its running well
@darman82 - The main purpose is to channel linkjuice upward to help with rankings. The byproduct and side benefit of doing that is it helps get your backlinks indexed.
Of course, you can setup an extra tier just because you want to help the last tier get indexed. But it still funnels linkjuice.
The more projects you add, the more links you build. It gets spread over all the projects. I'm sure there is a point where SER can't build anymore, and you either need more proxies - which gives you more threads.
Or you get into a poweruser status where you get additional licenses of SER and additional pc's. At that point you will be happy to do so because you are making a lot of bank
