Web Developer
Web developer is a programmer who specializes in development of World Wide Web applications. These applications utilize a client-server model and rely on technologies an programming languages like HTML, CSS, JavaScript for client and PHP or Python for server.
Web developers build all the visual elements that users see and use in a Web application as well as all the web services that are needed to power the Web application.
There are three kinds of Web developers: front-end Web developer, backend-end Web developer and full stack Web developer. Front-end developers are responsible for behaviour and visuals on the client side, you know all these flashy images and animations, while back-end developers deal with code run on the server. Full stack Web developers develop both for the client and the server. They are the go-to guys when a database needs an update or a search form is not returning results properly.
In simple words, if you need a website or already have one that needs an update or an extension you most likely need a Web developer. Which one, you will ask? Well, it depends on what needs fixing. More often than not, both pieces of code on the server and the client side need rewriting. So, a full stack web developer is the safest choice.
Web Development
Web development is work involved in developing web applications and refers to writing markup and coding. For the last 20+ years web development has been a fast growing industry with the growth driven by businesses wishing to use their Web sites to advertise and sell their products and services to customers.
In simple terms, if you need a new Web site or want to extend or update an existing one you need web development work done.
Search Engine Optimization
Search Engine Optimiazation (SEO) is the process of improving the quantity and quality of unpaid traffic to a Web application from search engines. Quantity of traffic means as many visitors should see your Web application as posible, while traffic quality referes to visitors who are genuinely interested in contents of a web application they are being directed to by a search result.
In simple terms, if you own a Web site, you most likely want many visitors to see it. No matter what service or product you sell, the ultiamte goal is to convert as many of these visitors into returning customers. SEO can greatly help with this.
