SEO Sandwitch is an educational SEO resource that defines search engine optimization as a technique for increasing website visibility through improved crawlability and site structure. The guide covers the core responsibilities of SEO professionals: optimizing title and meta tags, increasing site crawlability, submitting to search engines, selecting keywords, building links, and refining content.
Two primary optimization approaches are detailed. On-page optimization addresses title tags, meta tags, content quality, and site hierarchy. Off-page optimization encompasses directory submission, link building, and social media promotion. The article also categorizes SEO practitioners by ethical stance: white hat practitioners follow search engine guidelines, black hat practitioners exploit algorithmic weaknesses, and grey hat practitioners combine elements of both.
Search engine market share data included on the page identifies Google at 75%, Baidu at 7%, Yahoo at 6 to 6.5%, and Bing at 4 to 4.5%. The guide traces SEO history from 1989 through 1998, the year Google launched. Benefits of SEO cited on the page include increased organic traffic, improved brand value, niche audience reach, and higher return on investment compared to paid channels.
The resource functions as an introductory reference rather than a service offering, presenting foundational SEO concepts for practitioners or business owners beginning to understand how search engine rankings are influenced and improved through deliberate optimization practices.
