Challenge

They approached Black Marlin Technologies to expand their business and increase their client base. Despite having a website, they could not rank well in the search engines. It resulted in a significant setback because the company primarily focuses on online services.

Solution

Result

Challenge

A new tourism business targeting global customers needed a fully functional website with booking capabilities, a customer-friendly interface, and a plan to drive traffic and bookings through both paid and organic marketing channels. The client required a quick turnaround to launch their business and build visibility in a competitive market.

Solution

We built a fully optimized WordPress website from scratch within 10 days, featuring a robust booking engine and a ChatGPT-powered chatbot trained specifically to assist customers with bookings and inquiries. We launched Google Ads and Instagram Ads targeting global travelers, focusing on driving immediate bookings. We implemented a comprehensive SEO strategy to drive long-term organic traffic. As part of our ongoing service, we launched email marketing and referral programs.

Result

The Google and Instagram ads yielded immediate results, achieving an excellent return on ad spend (ROAS) of 4:1. Within 3 months of implementing our SEO strategy, the client began receiving organic leads, which reduced reliance on paid campaigns. By the 7th month, the client fully transitioned to organic efforts, relying solely on our SEO, social media organic strategies, and email marketing. As a result, the business consistently received bookings, proving the success of our organic strategies.

Challenge

Client is a fashion jewelry brand and had a vision to become a go-to destination for Gen Z in India. The competitors were not only other fashion jewelry brands, but also popular marketplaces. They came to us soon after the website launch and were fairly new in the market with almost nil domain history.

Solution

We used SEMrush, Google Keyword Planner, and Search Console to conduct in-depth keyword research and analyze competitors’ ranking keywords. Based on industry trends, we recommended pages for events like Valentine’s Day, Diwali, Christmas, and New Year to capture peak traffic periods. To attract Gen Z and young professionals, we published blogs beyond fashion jewelry to draw a wider, relevant audience. We grew traffic by launching more collection pages, targeting a broader range of keywords.

Result

Google 1st page ranking for ~1,100 keywords Google Top 3 positions for ~300 keywords In total ~14.8k keywords in SERP Organic traffic growth from 721 to 152k in 15 months
