The monthly-retainer figures in the table above come from prices these Kolkata providers publish on their own websites. Each one links to the page it was read from, with the date we last checked it:
- DotCreative: published monthly SEO packages at Local Business ₹10,000/month, Small Business ₹15,000/month, Midsize Business ₹25,000/month and E-commerce ₹40,000/month. The same page's FAQ states packages “start from Rs.5,000/month for local businesses and go up to Rs.50,000/month for e-commerce” (dotcreative.in, as published on 29 Sep 2026).
- Simple SEO: publishes a guide to what SEO costs in Kolkata, quoting freelancers at ₹8,000–₹20,000/month, mid-sized agencies at ₹15,000–₹50,000/month and premium agencies at ₹50,000–₹1,50,000+/month.

Note: If you require ongoing daily social media posting, dedicated monthly link-building, or complex enterprise software development, a full-service retainer agency or dedicated engineering team is the recommended choice.
