What is SEO in social media?

24 June 2026 · By John Carlsson

SEO in social media means using the words people search for in your profile bios, captions, titles and post text, so your profiles and posts are easier to find. Platforms such as TikTok, YouTube, Instagram, Pinterest and LinkedIn have their own search, and well-optimised profiles can also appear in Google results.

Social media SEO, or SEO in social media, refers to applying search optimisation principles to social media profiles and content, with the goal of making them more discoverable within those platforms or through general search engines. This involves researching and incorporating relevant keywords into profile bios, post captions, titles, and written content. Well-optimised social profiles can appear in both platform-native searches and broader web search results.

How social media platforms have become search engines

TikTok, Instagram, YouTube, Pinterest, and LinkedIn all have internal search functions that users use to discover content, businesses, and people — in many cases, younger users are turning to these platforms for search that would previously have gone to Google.

Each of these platforms uses its own ranking logic, but the fundamental principles of SEO in social media are similar to traditional SEO: content that uses the words people are searching for, from accounts that demonstrate credibility and engagement, tends to surface more prominently. For many businesses, appearing in platform search within their target audience's preferred app is as valuable as appearing in Google.

Practical techniques for SEO in social media

The most directly actionable technique is keyword research applied to social profiles rather than web pages: understanding which terms your target audience uses on each specific platform and incorporating them naturally into your profile bio, display name where possible, post captions, and content descriptions. Hashtags function similarly to keywords on platforms that use them. Alt text on social media images (now available on most platforms) serves the same purpose as website image alt text — both making content accessible and providing a text signal for platform algorithms. The consistency of your account's topic focus also matters: accounts that consistently publish about one subject area tend to be surfaced more reliably for searches on that topic.

How social media presence affects traditional web SEO

Social media doesn't directly improve Google rankings in the way backlinks do — Google has stated it doesn't use social shares as a ranking signal. The indirect effects are real, though: popular social media content can earn backlinks from people who share or write about it, increased brand awareness drives more branded searches (which are a strong quality signal), and social profiles themselves often rank prominently in branded search results. The most practical connection between social media and web SEO is that good social presence builds the brand awareness and earned backlinks that feed into authority building over time.

Frequently asked questions

How do you use SEO in social media to optimise a profile?

Optimising a social profile starts with keyword research for each specific platform, working out which terms your target audience actually uses there. Those terms should then be worked naturally into your profile bio, your display name where possible, post captions and content descriptions. Hashtags act much like keywords on platforms that use them. Alt text on images, now available on most platforms, makes content accessible and gives platform algorithms a text signal. Keeping your account focused on one consistent subject area also helps, because accounts that regularly publish about one topic tend to be surfaced more reliably for searches on it.

Do social media shares help Google rankings?

Social media does not directly improve Google rankings in the way backlinks do, and Google has stated that it does not use social shares as a ranking signal. The indirect effects are real, however. Popular social content can earn backlinks from people who share it or write about it. Greater brand awareness leads to more branded searches, which are a strong quality signal. Social profiles also often rank prominently in branded search results. The most practical link between social media and web SEO is that a good social presence builds the brand awareness and earned backlinks that feed authority over time.

Why are social media platforms now treated as search engines?

TikTok, Instagram, YouTube, Pinterest and LinkedIn all have internal search functions that people use to discover content, businesses and people. In many cases, younger users now turn to these platforms for searches that would previously have gone to Google. Each platform has its own ranking logic, but the core principles resemble traditional SEO: content that uses the words people search for, from accounts showing credibility and engagement, tends to appear more prominently. For many businesses, showing up in platform search inside the app their target audience prefers can be as valuable as appearing in Google results.
