I handle your Link Building strategy, placement, and account management end-to-end. - Here's how it works: You pay market rate for the links themselves (no markups, no hidden margins on top of the links). Just what they actually cost. On top of that, you pay a management fee for my work: strategy, placement, and reporting. What you get: - Custom link building strategy aligned to your goals - Direct access to high-quality & relevant websites - Entity stacking, press distribution, guaranteed indexation - Monthly reporting and performance tracking (GSC) - Full account management (just like having an agency, but without the overhead) Pricing: Management fee: $800–1,500/month (depending on campaign scope) Link costs: Fully transparent. You pay exactly what they cost at market rate, no markups. - Why this works: First, we need to have a call where you'll walk me through your business. And I need to know everything that might be relevant to our campaign from a ROI/revenue perspective. What service/product we should focus on? Which one you sell better or have the best margins? The next step is to understand, from an algorithmic perspective, the market benchmarks. And the way to do that is to reverse engineer your competitors SEO and link strategies. Once I add my secret sauce to the game, we can start execution. And here's where you have my most fair and honest play: you're not paying extra for the links. If X hundred dollars is the fair market price, comparing different providers and direct publishers, you pay X, not X + 40% margins. You're not paying for cheap corners cut to pad my margins. You're paying for strategy and execution. That's it. - My experience: I've managed campaigns across iGaming, SaaS, e-commerce, and local services. Let's talk about what your goals are and I'll give you a clear breakdown of cost and strategy.
