There are so many web development companies out there and they all say the same things. How do you actually tell which ones are good?

Check their portfolio first. If their previous work looks outdated or doesn't function well that tells you everything you need to know

Portfolio matters but also pay attention to how they communicate during initial conversations. Do they ask about your business goals or just try to sell you packages immediately? I spent weeks researching before finding the right fit. Looking at a web development company site gives you a sense of how they present themselves professionally. If their own website is slow or poorly designed that's a red flag. Also read actual client reviews beyond just testimonials on their homepage. Good developers understand business objectives not just coding. They should explain things clearly without overwhelming you with technical jargon you don't need
