We compare kinds of provider rather than naming firms, because the label on the door tells you far less than how the work is actually staffed.
A freelancer
Lowest monthly outlay
Where it wins: Cheap, fast to start, one person who answers the phone and knows your business well.
Where it breaks: One skill set and one calendar. Design, ads, SEO and development rarely live in the same person, and a wedding, an illness or a better client stops your marketing entirely.
Best for: A single-location shop that needs posts and a Business Profile kept alive, nothing more.
A local Siliguri agency
Mid range
Where it wins: Knows the market, the seasonality and the language your customers search in. You can walk into the office. Turnaround on approvals is hours, not weeks.
Where it breaks: Quality varies enormously. Some are genuine teams, some are one person with a reseller panel. The gap is invisible from the website, which is why the questions below matter.
Best for: Most Siliguri and North Bengal businesses that want accountable, measurable growth.
A metro agency in Kolkata, Delhi or Bengaluru
Highest monthly outlay
Where it wins: Deep specialist benches, big-brand process, strong creative production capacity.
Where it breaks: Your account is small to them, so it goes to a junior. They do not know that Sevoke Road traffic behaves differently from Hill Cart Road, or that a Bengali hook outperforms English copy here.
Best for: National D2C brands with large budgets and no local search dependency.
Hiring in-house
Salary plus tools, usually the most expensive route
Where it wins: Full attention, full control, knowledge stays in the building.
Where it breaks: One salary buys one skill. You still pay separately for design, ads tooling and development, and you carry the hiring risk and the training time.
Best for: Businesses already spending heavily on media every month, where a full-time owner pays for itself.
