As for now, SEO (acronym for Search Engines Optimization) can be divided into two separate fields: On-site and Off-site optimization.
Let’s discuss an important part of the later one.

While going through the first steps of designing a new website, or redesigning an existing one, it is extremely important to give some weight into Information Architecture. Websites who are designed from scratch with user accessibility in mind, tend to receive more love from SE, and of course, from the visitors themselves.
A Designer need to know to whom the website is intended for, and then with the help of some research, to create a system which is intuitive and comfortable for visitors.

Since the great importance of this matter, it is not to be taken lightly, and one should consider outsourcing its’ Information Architecture, Design and Organization.
Information Architecture done correctly, sometimes planned weeks before the first line of HTML ever written, can make all the difference between a site that gets 3-4 hits per day to a high ranking website with hundreds of visits, leads and a high conversion rate.

You’d be amazed to discover that websites’ owners often forget their visitors (or maybe you won’t). They ask the designer to work on the site until it looks great on their 9″ black & green computer screen; even if it means that the site will not be accessible to the majority of their users (I’m speaking from experience that really happened!).So first of all, if you are still using one of these old 9″ black & green computer screens ג€“ don’t be so cheap! Buy a normal one. 19″ would be nice but the minimum is really just 17″.
Second, and this tip is important in many aspects in life: If you already invest your money and hire a professional to design your website or blog, listen to what they have to say. Trust their experienced advices & instincts. Do not hire someone you don’t trust to begin with, or you will waste a lot of time hesitating before you actually get any work done. When you do feel you hired the right person (me perhaps?) make sure to incorporate your intimate knowledge of your business with your designers’ skills, talent and experience.
That should help the designer to make the best website they can for you and get you the best value for you money.
