Some web designers/developers like to install WordPress manually to get a custom install of the components they want and don’t want. Others will need to manually install because their web host does not have the “1-click-installation” capability. If this applies to you then you’ll need to have a quick read through of my Manual WordPress Set-Up Guide.
As far as actually doing the nuts and bolts building and design of your site, you also have plenty of options. You can hire someone to design and code a website, or you can try your own hand. You can use an online service to create web pages, or build it offline using a desktop software tool. Or, if you're a coding dynamo, use a plain text editor to create a site from scratch. How you mix and match these decisions depends on your skills, time, budget, and gumption.

SEO Web Design is a way of designing and developing websites to make them search engine friendly. Making a website SEO friendly means the search engines can crawl each page on the website efficiently, interpret the content effectively, and index it in their database. Once indexed, they can then serve the most relevant and valuable web pages to their users based on the topics they search for. The better the SEO strategies and the more an SEO team is integrated into the web design process, the better the chance of indexation and ranking on the first page of the search results.
