Description of “Diggity SEO On-site SEO Guide v1.18”

The Diggity SEO On-site SEO Guide v1.18 is a comprehensive and continually updated handbook on on-site optimization strategies, authored by Matt Diggity, a seasoned SEO professional with years of testing-backed experience. This guide is designed for digital marketers, business owners, and SEO practitioners who want a clear, data-driven roadmap for improving website rankings in an ever-changing search landscape.

At its core, the document emphasizes that on-site SEO is the foundation of all successful search engine optimization. Diggity uses a helpful analogy: backlinks may provide the “fuel,” but without a well-built “car” in the form of strong on-site optimization, websites remain stuck on page two or lower. To solve this, the guide walks readers through every essential component of optimization, breaking down techniques into actionable steps.

The document begins with Version History, showing its evolution since 2014, with the latest update in January 2025 addressing Google’s shifting trust algorithms. This history reinforces that the strategies provided are not outdated theories but refined practices tested against current conditions.

In the Introduction, Diggity shares his background and credibility, outlining his roles in multiple successful SEO-related businesses, including The Search Initiative and the Chiang Mai SEO Conference. He explains that his strategies stem from controlled testing rather than speculation, offering readers confidence in the methodology.

The first major section, High-Priority Keyword Holders, explores where keywords have the most impact: URLs, title tags, meta descriptions, and headers. Diggity explains the nuances of exact match domains (EMDs), partial match domains (PMDs), and branded domains, providing guidance on when to use each. He stresses precision, brevity, and natural phrasing, warning against outdated keyword stuffing practices.

The Content section is a deep dive into structuring and optimizing on-page text. Readers learn how to use header tags correctly, balance keyword density, incorporate synonyms, and optimize for multiple keywords without cannibalization. Diggity also introduces advanced concepts such as entity analysis, which leverages Google’s natural language processing to improve topical relevance. Practical tips are included for securing featured snippets, adding authority links strategically, and optimizing images, videos, and map embeds to boost engagement.

Another key concept is Siloing, which involves structuring internal links to maximize the power of backlinks. By organizing content into topical clusters and interlinking strategically, websites can distribute link equity effectively while reinforcing relevance. Diggity highlights the importance of linking subpages back to the homepage to recycle authority.

Schema Markup is addressed next, with step-by-step instructions for implementing structured data to help Google better understand website content. The guide explains how schema can enhance local SEO, improve click-through rates, and even earn coveted review stars in SERPs.

In the section on Fresh Content, Diggity underscores the importance of regularly updating websites. He advises creating at least one new blog post per month and refreshing existing pages with small but meaningful updates to satisfy Google’s Freshness Algorithm.

Keyword Cannibalization is presented as a common pitfall, where multiple pages compete for the same keyword, reducing overall rankings. The guide provides solutions such as optimizing metadata differently, using synonyms, and adjusting internal anchors to clarify each page’s unique purpose.

Finally, the guide offers WordPress Setup Recommendations, including essential plugins like Yoast, Rank Math, and Contact Form 7, as well as adjustments to permalink structures and crawl budgets. Diggity’s recommendations ensure that technical foundations align with SEO best practices.

Throughout the guide, the tone is practical and direct, mixing foundational SEO principles with advanced tactics. Each section is supported by examples, pro tips, and references to further resources.

In summary, the Diggity SEO On-site SEO Guide v1.18 is a valuable resource for anyone serious about achieving page-one rankings. It combines years of real-world testing with clear instructions, covering everything from keyword placement and content structure to schema and internal linking. By following its strategies, readers can create websites that are not only optimized for search engines but also structured for long-term growth and adaptability in a constantly evolving digital landscape.
