The web design industry has a trust problem. Thousands of businesses in Tanzania, East Africa, and globally have paid for websites that never delivered the results they were promised. Slow sites. Templates sold as custom. Developers who disappeared after delivery. Support that stopped the moment payment cleared.
This guide gives you 7 concrete checks to perform before you pay any agency or freelancer. Follow all 7 and you'll eliminate 90% of the risk.
Check 1: Look at Their Live Portfolio On Your Phone
Not their proposal documents. Not their mockup screenshots. Their actual, live websites. Open each one on your phone and ask:
- Does it load in under 3 seconds?
- Does it look and work properly on mobile without zooming in?
- Does the design look modern or like it's from 2015?
- Does every link and button work?
- Is there variety or do all their sites look identical? (The same-looking sites = one template used repeatedly)
If an agency says "our portfolio isn't public" or "clients didn't want their sites shared" walk away. Good work gets shared. And while you're evaluating their sites, check our list of signs your website needs a redesign the same quality indicators apply.
Testing a portfolio on your actual phone is the most honest evaluation of a web designer's mobile-first capability.
Check 2: Ask About SEO Before the Budget Conversation
Many agencies say "yes, we do SEO" but only mean they'll add a title tag. Real SEO at the build stage includes:
- Schema markup (structured data) on all relevant pages
- Sitemap generation and Google Search Console setup
- Proper meta tags on every page not just the homepage
- Page speed optimisation (compressed images, minified code)
- Mobile-first implementation
Ask them to explain what they do for SEO. If they look confused or give vague answers, they're not doing real SEO. Our guide on what SEO is and why it matters will help you evaluate their answers intelligently.
Check 3: Get a Written, Itemised Quote
A professional agency gives you a written proposal that specifies:
- Exactly which pages are included
- What technology/platform will be used
- Whether hosting and domain are included (and costs if not)
- SEO and email setup included or extra?
- Timeline with a clear delivery date
- Post-launch support what's covered, for how long, at what cost?
A verbal quote is no protection at all. If scope isn't written down, it doesn't exist. Before agreeing to anything, understand the full picture of what a website costs in Tanzania so you can evaluate whether the quote is fair.
Check 4: Understand Who Owns the Code
This is one of the most important questions you can ask and most business owners don't think to ask it. After delivery, do you own 100% of the website code?
The right answer is: "Yes, you own everything all source files, the database, all assets, all credentials."
Red flag answers include: "You have access to the admin panel," "You can manage content but the code is ours," or any equivalent that means you can't take your website to a different developer without starting over. Vendor lock-in is a business risk avoid agencies that build it into their model.
Check 5: Test Their Communication Speed
Send them a WhatsApp message or email today. How long do they take to respond? Not just for sales enquiries ask a specific technical question: "What page speed score do your sites typically achieve?" or "Do you include schema markup as standard?"
The communication speed and quality you experience during the sales process is a reliable preview of the support experience after you pay. Agencies that respond quickly and thoroughly before payment tend to do the same after.
Check 6: Ask for References From Similar Businesses
An agency that has built websites for tourism companies knows the challenges of tourism websites. One that has built for service businesses understands service business needs. Ask: "Do you have clients in a similar industry to mine that I could speak with or whose sites I could look at?"
If they can't provide any relevant examples, they may be competent but learning on your budget.
Check 7: Understand the Post-Launch Support Terms
"We offer ongoing support" means nothing without specifics. Ask:
- If something breaks after launch, what's the process?
- Is there a cost for bug fixes in the first 30/60/90 days?
- What's the hourly or per-task rate for changes after the support period?
- Is there an ongoing maintenance package available?
A website requires occasional attention updates, security patches, content changes. Know exactly what you're getting before you commit.
Red Flags: Walk Away If You See These
- 🚩 Price seems impossibly low quality web development has a cost floor. Pricing dramatically below market rate means corners are being cut somewhere
- 🚩 No portfolio or only mockups/screenshots real developers have live sites to show
- 🚩 100% payment required upfront professional agencies use milestone-based payment (typically 50/50)
- 🚩 No written contract or agreement this protects both parties; anyone refusing to put terms in writing is a risk
- 🚩 They can't answer SEO questions a website built without SEO understanding is a wasted investment
- 🚩 The timeline feels unrealistically short "your 20-page website will be ready in 3 days" is not a feature, it's a warning
The bottom line: The best indicator of a good agency is a combination of live work you can verify, transparent communication, and clear written terms. Price is a factor, but it should be the last thing you evaluate after quality, ownership, and trust are confirmed.
Frequently Asked Questions
Both can work well. Local agencies understand the Tanzania market M-Pesa integration, local SEO, Kiswahili content, cultural context. International agencies may have broader portfolios but lack local market knowledge. For most Tanzanian businesses, a local agency that meets all 7 criteria in this guide will deliver better value than a more expensive international one that doesn't know the market.
A skilled freelancer can deliver excellent results at a lower price point the risk is continuity (what happens if they're unavailable). An agency offers a team, backup cover, and more structured processes usually at a higher price. The most important factor isn't the model; it's applying the 7 checks in this guide regardless of whether you're evaluating a freelancer or an agency.
Come prepared with: your business overview (what you do, who your clients are), any competitor websites you admire, a rough list of pages you need, your approximate budget range, and your timeline requirements. The more specific you can be, the more accurate your quote will be. Agencies that ask you these questions upfront are the ones worth working with.
