Why you should do SEO
Your potential customers google for products and services they are looking for. Like PPC (pay per click) advertising, SEO will help your website to appear on these search results, allowing potential customers to find your business. Furthermore, if you already have a PPC account up and running or are planning to get started with PPC in the future, research shows that having your website appear in both the paid (PPC) and organic (SEO) listings has more beneficial effect as compare to just one channel. This can be explained by the increased respect and authority given to your brand by searchers because your brand is more favorable placement in the search results.
What to Expect
SEO can be a process of building your websites credibility and relevance over time. Whilst results may not be visible for 6-12 months, thus SEO is seen as a long-term marketing strategy. SEO is worth the effort because once the results start to become prominent it can be a very cost effective and sustainable source of traffic to your website.
