Around 2018, one of the hottest debates in the SEO community was whether social signals, such as likes, shares, comments, and followers, had any influence on Google rankings. Correlation studies showed that pages ranking at the top often had strong social engagement, leading many marketers to conclude that social activity was a ranking factor. Google, however, told a different story. Understanding what happened then helps clarify how social media and SEO relate today.

Their team integrates social promotion with SEO strategy so that every piece of content reaches more people and earns the authority signals search engines value.
What Are Social Signals?
Social signals refer to the collective engagement a website or piece of content receives on social media platforms like Facebook, X (formerly Twitter), LinkedIn, Pinterest, and Instagram. They include shares, likes, retweets, comments, pins, and follower counts. The theory was that content with more social engagement must be more valuable, so search engines would reward it.
What Google Said About Social Signals in 2018
Throughout 2018 and the years around it, Google representatives consistently stated that social signals were not a direct ranking factor. John Mueller, a Google Search Advocate, explained that Google does not use social shares or likes to rank pages. Earlier, Matt Cutts had noted that Google could not reliably crawl all social data and that relying on signals which could disappear or be blocked would be risky.
There were several practical reasons behind this position:
- Many social platforms restrict crawling, so Google cannot see complete engagement data.
- Social metrics are easy to manipulate with fake accounts and purchased likes.
- Most social links use nofollow attributes, which do not pass traditional link equity.
- Engagement fluctuates quickly and is not a stable measure of quality.
Why Correlation Studies Suggested Otherwise
Studies from that era showed that top-ranking pages often had more social shares. But correlation is not causation. High-quality content naturally attracts both social shares and backlinks. The backlinks and user engagement were likely driving rankings, while social shares were simply another symptom of great content. In other words, the same underlying quality produced both outcomes.
The Indirect SEO Benefits of Social Media
Even though social signals were not direct ranking factors in 2018, social media still provided meaningful SEO benefits, and those benefits remain relevant.
Increased Content Visibility
Sharing content on social platforms exposes it to people who might never find it through search. Some of those people are bloggers, journalists, or website owners who may link to it, creating valuable backlinks.
Brand Awareness and Branded Searches
Consistent social activity helps people remember your brand. When they later search for your name or products, branded search volume increases, which reflects demand and trust.
Faster Discovery and Indexing
Popular content shared widely tends to attract visits and links quickly, which can help search engines discover new pages sooner.
Social Profiles in Search Results
Social media profiles often rank for branded searches, giving businesses more control over the first page of results for their name.
Audience Insights
Social engagement reveals which topics resonate with your audience. These insights can guide keyword research and content planning for SEO.
How Things Have Evolved Since 2018
Since 2018, the relationship between social media and search has grown more complex. Google began indexing more social content, such as select posts and short-form videos, in search results. Platforms like TikTok, YouTube, and Reddit have become search destinations in their own right, especially for younger audiences. Meanwhile, AI-driven search experiences draw on discussions from forums and social communities when forming answers.
Social signals still are not a direct ranking factor for traditional web pages, but visibility across social platforms now influences how often a brand is discovered and cited in broader search ecosystems.
Best Practices for Using Social Media to Support SEO
- Share every new piece of content across relevant platforms with tailored messaging.
- Make it easy for visitors to share your content with visible sharing buttons.
- Engage with industry influencers who may reference or link to your work.
- Keep brand names, descriptions, and links consistent across all profiles.
- Repurpose blog posts into videos, carousels, and infographics to extend reach.
- Use social listening to find content ideas and questions your audience asks.
Integrating Social and Search Strategies
The most successful brands treat social media and SEO as complementary channels. Social builds awareness and distribution, while SEO captures demand from people actively searching. Combining both within a unified digital marketing plan ensures content reaches its full potential. Pairing that with professional SEO services turns increased visibility into lasting rankings.
Final Thoughts
So, did social signals matter to Google in SEO 2018? Not directly. Google was clear that likes and shares were not used as ranking factors. However, social media played an important indirect role by amplifying content, attracting backlinks, and building brand recognition. That lesson still applies today: use social platforms to spread great content, and the SEO benefits will follow through the signals Google actually measures.
