I provide SEO services, Google AdWords management & optimization, and WordPress services as a freelance consultant mostly to small businesses. I have 13 years of experience using SEO, AdWords, and WordPress. I also use Google Analytics and Google Search Console.
SEO infographics were my first exposure to the medium and really boosted my skill set and SEO knowledge. There are 100's of thousands covering the SEM industry and they really took off because it was (and probably still) is a great method of obtaining backlinks to your website.
