⟩ Tell us what services do they offer?
Commonly it assumes that a web design company offers web development, hosting, copywriting, e-commerce solutions, digital marketing services like SEO, social media or PPC management are related to each other whereas, in fact, these are different services from each other which require the different skillset.
Never assume that a company is good at one thing just because they are offering another. Almost every web design and development company are now offering digital marketing services too but don’t rely on them and let them handle all the digital work unless you get a solid, the desired result.
