I've been doing SEO for almost 9 years. There are generally three tenants in SEO:
1. Technical - Not only auditing the website to address SERP roadblocks but looking areas to increase your exposure across all verticals. For example, mobile/app optimization, international SEO, website migration and relaunches, SERP Analysis, site architecture, log file analysis, Google News, AMP, Facebook Instant and more.
2. Content - Outlining and reviewing your keyword mapping strategy in order to maximise and optimise your sites content performance.
3. Links - Analysis, audit and competitor and tactical plan to earn reputation, links, and topic authority.
I review your site, identify its strengths, weaknesses, opportunities, and threats and based on your objectives we formulate a long-term SEO strategy for you to take away and implement or assist in executing.
