Social SEO
The practice of optimising content for discovery and ranking within social media platform search functions (TikTok, Instagram, YouTube, Pinterest) — increasingly important as users bypass Google Search to search directly within social platforms.
Definition
Social SEO refers to optimising content for search discovery within social media platforms, where a growing proportion of users — particularly Gen Z — conduct topic research. The major social search surfaces: (1) **TikTok Search** — TikTok has developed a significant search behaviour, especially for "how-to", product reviews, and lifestyle queries. TikTok video SEO involves optimising captions (which TikTok indexes), video titles, on-screen text (which TikTok\'s OCR reads), spoken words in captions (auto-transcribed), and relevant hashtags. (2) **Instagram Search** — Instagram search covers accounts, hashtags, places, and audio. Caption keyword optimisation and alt text on images (accessible from advanced settings) contribute to Instagram discoverability. (3) **Pinterest Search** — Pinterest functions as a visual search engine and shopping discovery platform. Pin titles, descriptions, and board names are keyword-indexed. Pinterest SEO is distinct from other social SEO because it drives significant referral traffic to websites (unlike Instagram, which limits link access). (4) **YouTube Search** — covered in YouTube SEO, YouTube is a full search engine with algorithm signals distinct from Google web search. (5) **LinkedIn Search** — for B2B content, LinkedIn article and post discovery depends on profile and company page keyword optimisation. Social SEO and web SEO intersection: content that performs well in social search often drives branded search demand on Google (people searching for the creator or content they saw on a social platform), and social shares generate backlinks from third-party sites that embed or reference viral social content.
Why it matters for SEO
For consumer brands and content creators, a meaningful and growing portion of audience discovery now happens through social platform search rather than Google Search. Ignoring social SEO while focusing exclusively on Google means missing an increasingly significant discovery channel — particularly for audiences under 35.
How DeepSEOAnalysis checks this
DeepSEOAnalysis focuses on web page technical SEO rather than social platform content optimisation. The Open Graph and Twitter Card meta tag checks ensure content displays correctly when shared on social platforms, which affects click-through rates from social to the website.

Brand SEO
Brand SEO is the practice of optimising how your brand appears in search results — controlling branded search results, managing Google Knowledge Panels, building E-E-A-T brand signals, and ensuring brand mentions across the web support your search visibility. It differs from traditional keyword SEO (ranking for non-branded queries) by focusing on the brand as the ranking entity rather than individual pages.
