SEO and SEM are the tools you need to drive users to your website and increase traffic.
While search engine optimization is more concentrated on organic results based on content and unpaid search, search engine marketing strategies also include paid ads. An effective SEO/SEM strategy will increase traffic to your blog or company website, and that means more potential customers.
SEO & SEM Process
"Dude, where is my site?"
Do a search. Do you see your website? If not, then only a fraction of viewers will ever find you because only a fraction of viewers ever goes beyond page one of search results. SEO/SEM is the first step to improvement.
Make A Plan
Keyword research will point to how to optimise keywords, HTML tags, metadata and other content-related information to improve your rank on Google and other search engines. May have to include a paid ad campaign too.
Search engines change their algorithms so periodic reviews are crucial. Ads bring short-term results but keeping your site up to date staying search engine friendly brings enduring results. Let your budget and priorities be your guide.
