Spend time doing some research. What web set up do other organisations or individuals similar to you and yours have? Do you like it? How might it be improved? Which other websites do you like and why?
Will your online presence need regular updates or will it be a brochure site, ie. a static one that rarely changes?
How interactive do you want your webspace to be vs. how much time do you have to be interactive? For example: if you put a Contact Us page on a website, you will need to dedicate time to answering the messages you receive; if you use social media, you will need to monitor and update it.
Size matters – consider how extensive your webspace really needs to be vs. how much time you’ve got to put into it.
Content is king. Your online presence needs to be visually interesting, relevant and informative for your users. Whether you're building it yourself or getting someone else to do it for you, you will need to provide images and text at the very least. You might also have graphics and a logo. Be certain you have permission to use any images and graphics and make sure you give credit where credit's due.
SEO = Search Engine Optimisation. This is very important, because it will affect how easy it is for search engines to find your website and how close it will be to the top of the list when users search online.
Be organised and clear about what you want before starting to build. It's like baking a cake: the whole thing will be far easier (and more successful) if you've got tidy work surfaces, preheated the oven, got your tins ready and measured out your ingredients... before mixing it all together!
