Social media and SEO is the relationship between what a company publishes on social networks and its visibility in search engines. It is not a causal relationship: likes, shares and followers do not feed into Google's ranking algorithm. It is a relationship of occupied space. Social profiles and content rank on the first page of Google in place of company websites, get cited by AI assistants and generate brand searches that later reach the site.
One number to make the point straight away. Across 25 UK searches about LED displays, the domain that ranks in the top 10 most often is not a company in the sector: it is youtube.com, on 11 of the 25 queries. The best-placed specialist and eBay, which sells those products, reach 10 each.
What Google has said, with names and dates
The question has an official answer, repeated by three different spokespeople over fifteen years.
Matt Cutts, then head of the webspam team, stated in 2014 that follower and like counts are not included in the algorithm. John Mueller repeated it in 2015 and again in 2021, with the line that became the standard quote: "Sorry, we don't use likes as a ranking factor". Gary Illyes added the technical part in 2017: "PageRank wise most social media links count as much as a single drop in an ocean". Links from social profiles are almost all nofollow and pass no authority, so they do not work as backlinks in the sense that matters for ranking. The full collection of statements is on Search Engine Journal, and Patrick Stox at Ahrefs reaches the same conclusion from his own data.
This is where the most common misunderstanding comes from: since social signals do not move rankings, social activity supposedly has no effect on search. The conclusion skips a step, and the data below shows which one.
Social platforms take first-page positions instead of you
Google does not reward your YouTube channel because it has lots of views. But Google does index that channel, that video, that Facebook page and that Reddit thread, and puts them on the first page alongside company websites. Every position taken by a platform is a position no website can occupy.
We counted how often social domains reach the top 10 on two baskets of UK B2B queries, built on the two sectors we track for B2B clients in Italy. The first basket is 25 queries about LED displays and video walls, the second 25 queries about commercial and industrial solar. Data from Google UK, September 2026.
| Domain | Basket A: 25 queries (LED displays) | Average position A | Basket B: 25 queries (commercial solar) | Average position B |
|---|---|---|---|---|
| youtube.com | 11 | 6.4 | 5 | 9.0 |
| pinterest.com | 5 | 5.2 | not in top 10 | – |
| facebook.com | 3 | 8.7 | not in top 10 | – |
| reddit.com | not detected | – | 1 | 10.0 |
| Total social domains | 19 | 6.4 | 6 | 9.2 |
| Best-placed direct competitor in the sector | 10 | 2.4 | 7 | 1.9 |
| Marketplaces (eBay / Amazon) and comparison sites (basket B) | 15 | 4.9 | 15 | 6.2 |
In basket A, social domains together take 19 top-10 slots against 10 for the best-placed direct competitor. In an industrial sector, where nobody expects social content, YouTube on its own ranks on more queries than any specialist. Basket B is different: the platforms take only 6 slots, and the space goes to energy suppliers and comparison sites. On the Italian versions of the same two sectors, which we track daily for two clients, social domains weigh more: in LED displays they add up to 700 top-10 appearances in thirty days against 366 for the best-placed competitor.
The average positions tell the other half of the story: social domains sit between fifth and tenth position, specialist sites around second, marketplaces and comparison sites in between. Social platforms do not win the SERP, they fill it. On a B2B first page that rarely shows more than ten organic results, two or three positions taken by platforms change how many clicks are left. It is the same mechanism that makes raw organic traffic harder and harder to read without looking at the make-up of the SERP, a topic we covered in the guide to SEO strategy.
The practical consequence is less obvious than it looks: the platform worth publishing on is not chosen from demographics, it is chosen by looking at which platform already ranks in your SERP. In basket A it is YouTube, so video SEO is a direct investment in rankings. In basket B no platform holds a strong position, the comparison sites do, and the logic changes completely.
AI answers feed on social content
The second channel is more recent and far less discussed. Conversational assistants cite sources, and the sources they cite most are platforms of user-generated content.
Semrush analysed 230,000 prompts on ChatGPT, Google AI Mode and Perplexity over thirteen weeks, from 14 July to 12 October 2025, for more than 100 million citations. Reddit is the most cited domain overall, followed by Wikipedia, LinkedIn, YouTube and Forbes. On Google AI Mode, LinkedIn appears in almost 15% of answers. The study also records how unstable the picture is: on ChatGPT, Reddit's presence drops from around 60% of answers in August to around 10% in October 2025. Method and charts are in the Semrush study on the domains most cited by AI.
A second analysis, by Peec AI on 30 million sources across ChatGPT, Google AI Mode, Gemini, Perplexity and AI Overviews, puts the top three in the same order: Reddit, YouTube, LinkedIn. The summary is on Search Engine Land.
Two caveats before you take these numbers into a meeting. They are international samples, with prompts weighted towards the US: we are not aware of a UK-only equivalent, and a British B2B buyer's habits on Reddit are not necessarily those of an American consumer. And the presence of AI Overviews on industrial B2B queries can be low: on the two Italian baskets we track, in August 2026 AI Overviews appeared on between 1 and 3 keywords out of 135 in the first and on 1 or 2 out of 143 in the second. In markets like these, the battle for AI citations is fought inside ChatGPT more than inside Google, as we have seen working on how to appear in ChatGPT answers and more generally on generative engine optimisation.
How many people in the UK use social media to research a company
The Digital 2026 report for the United Kingdom by We Are Social and Meltwater measures the behaviour that sits upstream of everything else: 49.3% of UK adult internet users use social media to find information about products, and 38.7% use social channels to learn about brands and find their content. The figures are summarised on the We Are Social UK blog.
Time spent shows where attention goes: on Android devices, TikTok takes 1 hour 14 minutes a day, YouTube 1 hour, Instagram 46 minutes.
A figure that circulates widely is more extreme and should be kept separate. A survey by Researchscape International for Yext, carried out in June 2024 on 2,312 adults who had bought something online in the previous year, across France, Italy, Germany, the United Kingdom and the United States, found that an estimated 88% of users look to social media for more information about a brand and that 67% of Gen Z use social platforms directly to search for information about products or services. It is a sample of recent online shoppers across five countries, and 88% refers to social media users, not all internet users: the gap of almost 40 points with the UK's 49.3% says as much about who was asked as about behaviour, and anyone building a strategy on the higher number is planning for a different audience. The survey is published on the Yext blog.
The four real paths between social and search
1. Occupying the SERP
A well-kept profile that ranks for the company name takes space away from reviews, directories and third-party pages. In B2B it is often the only way to control the second half of the first page for your own brand, together with the Google Business Profile listing.
2. Citation in generative answers
A video, a LinkedIn post or a forum reply are indexable pages that assistants can cite. If you want to measure it, AI visibility tools are now mature enough to track which answers a brand appears in.
3. Brand demand
People who see content on social media often do not click: they search for the name on Google a few days later. That search shows up in Search Console as a brand query, not as social traffic, and in many reports it ends up credited to SEO. On the Visilay site, between 27 May and 24 August 2026, the most clicked query of all was "visilay": 22 clicks from 73 impressions, average position 1, CTR 30.1%. It is a small volume, but it shows how the mechanism works: brand demand is created elsewhere and harvested in organic search.
4. Entity recognition
Google's documentation on Organization schema includes the sameAs property, described as "the URL of a page on another website with additional information about your organization", for example a profile page on a social media or review site. It helps Google understand that those profiles and the website are the same entity. There is also the ProfilePage markup, which feeds the Discussions and Forums section in the results. It takes two lines of structured data, and hardly anyone implements them.
None of the four paths goes through likes. Three of the four depend on the fact that a social page is an indexable web page, something that almost always gets lost in the debate on "social signals".
What changes platform by platform
| Platform | What gets into search | Minimum action that makes sense |
|---|---|---|
| YouTube | Individual videos in the SERP and in video boxes, citations in AI Overviews | Title and description written around the query, transcript uploaded |
| Company pages and posts indexed, strong presence in AI answers on B2B queries | Complete company page, posts that answer technical questions | |
| Threads on the first page for comparison and opinion queries | Take part in existing threads about your sector, without spamming | |
| Instagram and Facebook | Profiles in brand SERPs, local presence | Name, category and links consistent with the Business Profile listing |
| TikTok | Search inside the platform, rarely seen in Google results for B2B queries | Optimise for search inside the app, not for Google |
On YouTube and TikTok the work is different from what you do on the website and deserves two separate approaches: YouTube SEO works on a real search engine, TikTok SEO on a recommendation engine with a search bar on top.
How to measure the contribution without fooling yourself
There is no attribution model that links a post to a ranking. There is, however, an honest way to measure, in three steps.
- Take the volume of brand queries in Search Console for the 90 days before starting social activity. That is your baseline. The queries report filtered on the company name is enough.
- Record referral traffic from the platforms in Google Analytics, bearing in mind that it always underestimates: apps open links in in-app browsers and part of the traffic arrives as direct.
- After 90 days, compare brand queries, not social sessions. If impressions on the company name rise while advertising spend stays flat, the signal can be attributed.
The fourth check is the one almost nobody does: search Google for your five main commercial keywords and count how many first-page positions are taken by social platforms. If there are two or more, that channel is not a communications activity, it is part of your search space. We wrote about how to put these numbers into a sensible dashboard in the guide to SEO KPIs.
Three ways to waste the work
Buying likes and followers. If social signals are not part of the algorithm, inflating them does nothing for rankings. All it produces is a profile with an inconsistent engagement rate, which the platforms penalise in distribution.
Using social media as a link building strategy. The links are nofollow and are worth, to quote Illyes, a drop in the ocean. Useful links come from people who see the content on social media and then cite it from their own site: it is a second-order effect, and should be planned as such in your link building strategy.
Republishing the full article on LinkedIn or Medium. It creates a second version of the same text that competes with the original and splits the signals. An excerpt with a link is better, for the reasons explained in the article on duplicate content.
If your sector is industrial and you are wondering whether it is worth it, the case described in the guide to SEO for manufacturing shows an Italian manufacturer that moved from position 88 to 2 on a commercial query and reached a 25.55% share of voice on its cluster, ahead of Amazon: the heavy lifting was on the website, but the first page it won is the same one where YouTube and Facebook appear. We work on this kind of project through our SEO and AI SEO services, and the logic of the four paths applies just as well to anyone setting up a B2B SEO strategy from scratch.
Frequently asked questions
No. Matt Cutts stated in 2014 that follower and like counts are not included in the algorithm, and John Mueller confirmed it in 2015 and 2021. Social media affects search in other ways: platforms take positions in the SERP, get cited by AI assistants and generate searches for the company name.
Not directly. Correlation studies show that well-ranked pages also get many shares, but the relationship runs the other way: good content gets shared and also gets linked, and it is the links that move rankings.
It depends on the SERP in your sector, not on demographics. On a basket of 25 UK B2B queries about LED displays, YouTube ranks in the top 10 on 11 of them. On 25 commercial solar queries it does so on 5, and Facebook on none. The right way to choose is to search your main keywords and see which platform shows up.
No. They are almost all nofollow and pass no PageRank. Google's Gary Illyes said in 2017 that in PageRank terms most social links are worth a drop in the ocean. The value of those links is the traffic they bring and the chance that someone, having seen the content, cites it from their own site.
It is if the platforms hold positions on your first page or appear among the sources AI assistants cite for your queries. Both checks take half an hour: search your five main keywords and count the positions taken by social domains, then ask ChatGPT or Perplexity a typical question from your sector and look at which sources it cites.
There is a reversal the industry rarely admits. For twenty years the question has been how much social media helps SEO, as if SEO were the end and social the means. Looking at these baskets, the opposite doubt arises: the platforms have become the place where search happens, and Google's SERP the place where those platforms meet. A company that publishes only on its own website is competing on a first page where part of the results come from places where it does not even have an up-to-date profile.
