Search engine optimisation
For your website to remain relevant and competitive on the internet it must be specifically targetted to a particular niche market. For instance, if you are a motor spare parts dealer and the majority of your clients are centered in the mainland area of Lagos state, rather than selecting a broad or generic keyword/keyphrase like 'spare parts' or 'spare parts dealer', it would be more profitable to use a more specific phrase like 'spare parts dealer in Lagos Nigeria' which are known by professional SEO as known in search engine optimization as long tail keywords. Your website would likely rank high in Google for using such long tail keywords than for using a generic keyword like spare parts dealer.
As far as search engine optimization is concerned, content is king! So you need to ensure that your website has well written content that's free of gramatical errors and that your content is regularly updated. This is why it helps to have a blog associated to your website. This will enable you write fresh content that will be of benefit to your customers. There is nothing Google loves better than seeing fresh original content on your website that is regularly updated. Your online business will suffer severly if your website is not regularly updated. This is because when search engines like Google crawl your website and don't notice any changes, sooner or later they will stop indexing your site and your website rank will drop drastically.
