I'd be interested to hear what you guys have had more success with. Sinking your whole budget into one 'expensive' SEO service (the type found on this forum ranging from around $100-$600), or using 2 or 3 cheaper services that total the same amount? (assuming you use quality services). My thinking is that perhaps it's better to go with several because the variation might leave less of a footprint and provide a more diverse link structure. On the other hand, if you find one really good service then it could be better to put more money into that rather than diversify. What do you think? For the record, I've only ever used one service. As my site is earning more I'm pondering whether to put more money into the service that has served me well already, or to diversify. Also, sorry if this is the wrong forum, I couldn't decide where this post should go!
