Ordering the development of a website and placing it on the Internet is not enough for the resource to become popular and start generating income. This requires high-quality promotion using search engine optimization (SEO), contextual, display advertising, etc. You also need to regularly fill the portal with interesting and unique content so that Internet users have an incentive to come back to you again and again.
Technical support is also important: timely elimination of errors, bugs, protection from hacks and attacks. But a design that reflects the interests and preferences of your potential customers is at the forefront. A design that disposes from the first seconds and subconsciously inclines to make purchases.
