TikTok and Instagram now drive over 60% of product discovery — surpassing Google — and short-form video delivers the highest ROI of any content format at 41%. For SMEs spending £500–£5k/month on social, that means your channel mix from 2024 is already out of date. This week: audit your social CAC by platform, cut any format with sub-1.4% engagement, and put at least 20% of your paid social budget behind short-form video creative.

TikTok and Instagram now outrank Google for product discovery — and your social ROI benchmarks need to catch up#
Here's the number that should change your Monday morning budget meeting: TikTok, Instagram, and YouTube collectively account for over 60% of product discovery in 2026, according to Sprout Social's analysis of 120+ social media statistics. Google, the channel most SMEs still anchor their acquisition strategy around, has been surpassed. Twelve months ago, paid search was the default first move for most SME founders with a £2k/month marketing budget. Organic social was a nice-to-have. Short-form video was something you tested with leftover budget. That calculus has flipped. The engagement rate benchmark for social media in 2026 sits at 1.4%–2.8% across platforms. If you're running brand content on Instagram or Facebook and seeing below 1.4%, you're not underperforming — you're invisible. Short-form video (Reels, TikTok, YouTube Shorts) is delivering 41% of total video ROI, the highest of any format, and 94% of organisations report influencer marketing outperforms traditional digital advertising, often at 2×–3× the return. For context on how fast this has moved: TikTok adoption among small businesses was 17% in 2023. It's now 33%, per the Small Business & Entrepreneurship Council. That's not a trend. That's a structural shift in where buyers find products before they ever type a search query. The implication for SMEs is direct: if your 2026 social strategy is still weighted toward static image posts on Facebook and occasional Instagram carousels, you're benchmarking against the wrong year. The platforms haven't just updated their algorithms — the buyers have moved.
What this means for a business spending £500–£5,000/month on marketing#
Take a Shopify homeware brand doing £60k/month in revenue, running £2,500/month across Meta Ads and Google Shopping. Until recently, that split — roughly 60% Google, 40% Meta — was defensible. Google captured high-intent search buyers; Meta handled retargeting and prospecting. In 2026, that same buyer is discovering the product on a TikTok video from a micro-influencer or a Reel served by Instagram's algorithm, then converting via a link in bio or a TikTok Shop product pin. If the brand isn't present at the discovery stage, Google Shopping is only capturing the buyers who already know what they're looking for — a shrinking slice. The cost reality: Meta CPMs for UK retail are running £8–£14 in Q2 2026 for prospecting audiences, up from £6–£10 in 2024. TikTok prospecting CPMs are still £4–£8 for the same retail categories, with higher organic amplification potential if the creative performs. That's a meaningful CAC difference on a £1,500/month paid social budget — potentially £18–£22 CAC on Meta versus £11–£15 on TikTok for equivalent audience targeting. For local service businesses with tighter budgets (£500–£800/month), the math is starker. Static Facebook ads at a £6 CPM with a 1.2% CTR and 3% landing page conversion rate give you a rough CAC of £167. A short-form video ad with a 2.4% CTR and the same conversion rate halves that to £83. The creative costs more to produce, but one good 30-second video — shot on an iPhone, edited in CapCut — can run for 6–8 weeks before fatigue sets in. 68% of small-business owners now say social posting and paid ads will drive the most value in 2026, per Constant Contact's January survey. The founders who are winning are the ones who have stopped treating short-form video as experimental.
The three moves smart SME marketers are making right now#
**1. Shift 20–30% of paid social budget to short-form video placements immediately** In Meta Ads Manager, move spend from static image ad sets into Reels-specific placements. Set a separate ad set targeting Advantage+ placements with Reels/Stories only — don't let the algorithm blend your video budget into Feed. Start with a £300–£500/month test. Your benchmark: aim for a 2×+ ROAS within 6 weeks or kill it. Use CapCut Business or Canva's video editor to produce 3–4 creative variants and A/B test hooks in the first 3 seconds. Watch your 3-second video view rate in Ads Manager — below 25% means your hook is the problem, not your audience. **2. Set up platform-specific engagement tracking in Google Analytics 4** Create UTM parameters for every social platform — separate campaigns for TikTok, Instagram Reels, Instagram Feed, and Facebook. In GA4, build a custom report under Explore > Funnel Exploration that shows sessions by source/medium, add-to-cart rate, and purchase conversion rate. Your benchmark: social traffic converting at below 1.2% to purchase means your landing page, not your ad, is the bottleneck. Run Hotjar on the landing page for one week to confirm. **3. Test a micro-influencer activation at £150–£300 per creator** With influencer marketing delivering 2×–3× returns versus traditional digital ads, even one paid UGC post from a creator with 5k–20k followers in your niche is worth testing. Use platforms like Intellifluence or Creator.co to find UK creators for under £200 per post. Repurpose the content as paid dark posts in Meta Ads Manager. Track attributed revenue via UTM links — this is where most SMEs leave money on the table by not closing the measurement loop.
How AskBiz tells you exactly which social channel is actually driving revenue — not just clicks#
A founder of a UK skincare brand, three months into a TikTok push, types into AskBiz: *"Which social media channel drove the most revenue last month, and what was my CAC per channel?"* AskBiz connects to their Shopify store, Meta Ads account, and Google Analytics 4 via its Marketing Analytics integration and returns this in under 10 seconds: *'Last month, TikTok drove £8,400 in attributed revenue — your highest-performing social channel. CAC via TikTok: £14.20. Meta Ads CAC: £31.80. Instagram organic: £6.10 CAC but only 18 orders. Your TikTok ROAS sits at 3.8× versus Meta at 1.9×. At your current budget split (£1,200 Meta / £400 TikTok), shifting £500 from Meta to TikTok would project an additional £1,900/month in revenue at current conversion rates.'* That's the decision the founder can act on before Friday. Without that channel attribution clarity — which most SMEs are missing because they're relying on platform-reported ROAS rather than actual revenue data — they'd have kept over-indexing on Meta based on a vanity metric. AskBiz's Proactive Alerts also flag when a channel's ROAS drops below a threshold you set — so if your TikTok ROAS slips from 3.8× to 2.1× after a creative refresh, you get the alert before the monthly report tells you.
Warning signs your social ROI is worse than you think#
Check these four signals in your accounts this week: **Meta Ads Manager → Campaigns → Columns (Customise) → ROAS**: If your blended paid social ROAS is below 2× and you're in retail or eCommerce, your creative or targeting has a problem — not your budget. **GA4 → Acquisition → Traffic Acquisition**: If social channels show bounce rates above 72% or sessions-to-purchase conversion below 1%, your ad-to-landing-page message match is broken. **Instagram/TikTok native analytics → Content → Reach vs. Profile Visits**: If reach is climbing but profile visits are flat (below 3% of reach converting to a profile visit), your content is getting served but not creating intent. **Klaviyo or Mailchimp → Campaigns → Source**: If email subscribers attributed to social have a 90-day LTV below £40 and your product AOV is £60+, you're attracting the wrong audience from your social ads — a targeting problem, not a product problem.
Your action plan for the next 7 days#
**Before Friday:** Log into Meta Ads Manager and pull a breakdown of your last 30 days by placement (Ads Manager → Breakdown → By Delivery → Placement). Identify which placements are consuming budget with a ROAS below 1.5× and pause them. Reallocate that daily budget to Reels placements with your best-performing creative. **Set up once:** In Google Analytics 4, go to Admin → Custom Definitions → Custom Dimensions and add a 'social_platform' dimension tied to your UTM campaign parameters. This gives you clean, channel-level conversion data in every report going forward — no more blended 'social' traffic masking which platform actually converts. **Track weekly:** Your social CAC by platform. Export it every Monday from your ad platforms and drop it into a simple Google Sheet — Date, Platform, Spend, Orders, CAC, ROAS. Four weeks of this data tells you more than any agency monthly report. If you're on AskBiz's Growth plan (£19/month), ask it every Monday: *'What was my social CAC by channel this week?'* — it pulls the answer directly from your connected ad accounts.

What is a good social media ROI for a small business in 2026?
A blended social media ROAS of 2×–4× is the realistic benchmark for SMEs spending £500–£5k/month in 2026. Short-form video campaigns on TikTok and Instagram Reels are hitting 3×–5× ROAS in retail categories. If you're below 2×, audit your creative format first — static images in 2026 consistently underperform video placements by 30–50% on cost-per-click.
What is the average engagement rate on social media in 2026?
The 2026 benchmark for social media engagement sits at 1.4%–2.8% across platforms. Short-form video content (TikTok, Reels, YouTube Shorts) trends toward the upper end. If your brand posts are consistently below 1.4%, cut that format. Double your output on whatever format is clearing 2%+ — that's your algorithm signal.
Why is my social media marketing not generating sales?
The most common cause: your ad-to-landing-page message match is broken. Check in GA4 — if social traffic has a bounce rate above 70% and a purchase conversion rate below 1.2%, the problem isn't your audience targeting, it's what happens after the click. Use Hotjar to watch session recordings on your landing page. Fix the page before you increase ad spend.
What does social media ROI mean for a small business?
Social media ROI measures the revenue or value generated from your social spend relative to its cost. For an SME, it's most usefully tracked as ROAS (revenue ÷ ad spend) per platform and CAC (total social spend ÷ new customers acquired). A Shopify brand spending £1,000/month on TikTok Ads generating £3,800 in attributed revenue has a 3.8× ROAS — calculated in Meta Ads Manager or GA4 with proper UTM tracking.
