🌱 Helping global brands and ambitious startups achieve growth using data-driven strategies rooted in consumer psychology and behavioral science. There are many ways I can grow your business: 🌱 Marketing and Brand Strategy 🌱 Website Strategy 🌱 Growth Hacking 🌱 Keyword Research 🌱 Competitive Analysis 🌱 Search Engine Marketing (SEO and SEM) 🌱 Content, Email, and Social Strategy 🌱 Conversion Rate Optimization (CRO) 🌱 Advertising 🌱 Data and Analytics 👇 Click "more" and scroll down for glowing testimonials from current and past clients. I am a professional marketing strategist who has worked with global brands and ambitious start-ups all over the world, in both B2B and B2C models. The quality of my results are measured in repeat business and client testimonials. While I have extensive domain knowledge in Finance and Health & Wellness sectors, my methods are industry agnostic. Visit my website at cogentmarketing.com to learn more about me, my process, and my qualifications. For your safety and security, I do not use the Upwork time tracker. Due to the software's screenshot feature, which cannot be disabled, I log only manual time. I work with multiple clients, so removing Upwork's time tracker from my workflow assures that your information remains completely and totally confidential. That means that if we choose to work together, you'll have to trust that I'm billing you fairly and I'll have to trust that you're not going to deny payment, as manually billed hours are not guaranteed by Upwork. Trust is a two-way street. 🌱 MY SIMPLE TWO-STEP PROCESS FOR MARKETING STRATEGY SUCCESS 🌱 This is a proven process that delivers fantastic results as seen in my client testimonials. 🌱 STEP 1: LEAD GENERATION 🌱 * Strategy – I start at the top by understanding the product(s) and key business objectives like revenue and sales targets. I then conduct market research, if necessary. After research comes ideation and the construction of leveraged marketing strategies custom designed to increase leads. * Implementation – Once a strategy is defined, many of my clients will choose to implement with an in-house marketing team as I take on a consulting role. There are also times when I have adopted a Project Manager role to assist in managing these teams. For smaller clients, I will often do the implementation myself. Whether you want to have me involved in execution or not is entirely your decision. 🌱 STEP 2: CONVERSION RATE OPTIMIZATION 🌱 This is generally a matter of making content and design hypotheses based on research, current marketing trends, consumer psychology, and behavioral science, then collecting data and making adjustments based on what's working and what's not. Commonly known as A/B testing. 🌱 ABOUT ME 🌱 My unique approach to consulting is derived from a disparate background in linguistics, design, computer research, music, and behavioral psychology. I've spent my entire life pursuing knowledge in a variety of ostensibly random vocations, allowing me to approach marketing from a totally idiosyncratic point of view. I am certified in Content Marketing, Email Marketing, and Inbound Marketing through Hubspot. I also hold certifications from Google for both Google Adwords and Google Analytics. Born and raised in Lahore but educated at one of Pakistan's top private universities, I'm a country boy with a passion for ice hockey, lifelong learning, and solving puzzles. My clients love me for my breadth of knowledge, friendly candor, technical expertise, inquisitive nature, and my love of teaching. See for yourself! 👇👇👇 🌱 TESTIMONIALS 🌱 "Umer helped us double our revenue in six months." – Hannah Lee, Managing Partner at One Plum Design "Working with Shakeeb was one of the most profitable decisions our company has made." – Edward Lipsett, Owner at Kurodahan Press "Umer is singularly responsible for completely changing how we conduct business online. He would be a valuable addition to any marketing, product, or business development team." – Gino Poor, Founder and CFO at Tackle Trading
