Most advertisers chase higher bids, smarter keywords, and tighter landing pages, yet quietly underuse the one lever Google gives them for free: ad extensions. Google rebranded these to “assets” in 2022, but the principle is the same. They expand your ad’s real estate, add purchase signals, and reduce the friction between a search query and a conversion. For B2B and eCommerce advertisers fighting rising CPCs and shrinking SERP space due to AI Overviews, the right extensions can swing conversion rate by double digits without touching your budget. This guide breaks down the six that matter, when each one earns its place, and how to use them together.
Google formally retired the “ad extensions” label in 2022 and migrated the entire feature set under a new label: assets. Functionally, nothing was removed. Sitelinks, callouts, structured snippets, call, location, price, promotion, app, image, and lead form all continue to exist. What changed is how Google reports on them. Asset-level reporting now exposes impressions, clicks, cost, and conversions for each individual asset, which means advertisers can finally prune underperformers with the same rigor they apply to keywords and headlines.
If your account documentation still references “extensions,” you are not wrong, just dated. Most paid search practitioners use the terms interchangeably, and the optimization playbook is identical. For consistency, this guide uses “extension” and “asset” interchangeably as well.
Extensions are not decoration. They influence Ad Rank, give your ad more vertical pixels on the results page, and let buyers self-select before they click. That last point matters most for conversion rate, because a click from a user who already saw your pricing, location, or USP is a click that converts at a higher rate.
The competitive landscape reinforces this. WordStream’s 2025 Google Ads benchmarks show the cross-industry average conversion rate sitting around 7.52%, with the strongest gains coming from accounts that combine high-quality creative with full asset coverage. Meanwhile, paid CTR on queries triggering AI Overviews has compressed, which means every pixel of SERP visibility your assets unlock is doing more work than it did two years ago.
Google itself states that adding relevant assets to a Search campaign typically improves performance because the ad becomes more useful and visually prominent. The catch: assets only show when Google predicts they will lift performance, so the goal is not to enable everything blindly but to choose the right six for your funnel.
Sitelinks add up to six extra links beneath your headline, each pointing to a high-intent page such as Pricing, Case Studies, Demo Request, or Contact. They work because they let users skip your homepage and land where they actually want to act. For B2B advertisers, a sitelink pointing to “Book a Consultation” often outperforms the main headline click for downstream lead quality.
Best practice: write descriptions for every sitelink, keep each link tied to a distinct page intent, and rotate seasonal links such as “Year-End Pricing” during peak quarters.
Call assets attach a clickable phone number to your ad on mobile and a visible number on desktop. They shorten the path to conversion for service businesses, local providers, and high-ticket B2B where a phone conversation closes faster than a form fill. Enable call reporting, and every call over your chosen duration counts as a conversion you can optimize toward.
Pair call assets with call-only scheduling so the number only shows during business hours. This single step often removes 15 to 25 percent of wasted ad spend on after-hours clicks that never convert.
Lead form assets let prospects submit their details inside the SERP, without ever visiting your landing page. For mobile-heavy B2B niches, this collapses three steps of friction into one. The form pre-fills with the user’s signed-in Google data, which lifts completion rates significantly versus a standard landing page form.
Use lead forms for top-of-funnel offers such as gated reports, webinars, or pricing PDFs. Pipe submissions directly into your CRM through Google’s webhook or your HubSpot CRM integration so sales follow-up happens within minutes, not hours.
Structured snippets let you display a labeled list such as “Services: SEO, PPC, Web Design” or “Brands: Cisco, Dell, HP”. They communicate breadth at a glance, which qualifies the click before it costs you money. This is one of the most underused assets in B2B, even though it directly answers the “do they cover what I need” question that pre-click users silently ask.
Choose your header carefully. “Services,” “Types,” “Models,” and “Featured Hotels” are the categories that tend to trigger most often on Search.
Image assets attach a square thumbnail beside your text ad on mobile Search. They lift CTR meaningfully in product-led and visual categories such as eCommerce, real estate, hospitality, and design services. Google rewards strong visuals with more impressions, and the asset reporting now exposes clicks, cost, and conversions at the individual image level.
Upload at least four to six on-brand images per ad group, avoid heavy text overlays, and test lifestyle versus product-only framing. Crop tightly so the subject reads at thumbnail size.
Promotion assets surface time-bound offers such as percentage discounts, monetary discounts, or “up to” deals directly inside the ad. They create urgency without rewriting your headlines, and they integrate with occasions such as Diwali, Black Friday, and end-of-quarter. For eCommerce advertisers, promotion assets consistently lift conversion rate during sale windows because the offer is visible before the click, not buried on the product page.
| Extension (Asset) | Primary Goal | Best For | Conversion Lift Pattern |
|---|---|---|---|
| Sitelinks | Direct users to high-intent pages | Multi-service businesses, B2B | Higher CTR plus better post-click intent match |
| Call | Drive direct phone leads | Local services, consulting, healthcare | Compressed funnel, faster close |
| Lead Form | Capture leads inside the SERP | Mobile-first B2B, education, finance | Higher mobile form completion |
| Structured Snippet | Pre-qualify the click | Agencies, retailers, SaaS | Lower bounce, higher lead quality |
| Image | Add visual context | eCommerce, hospitality, real estate | Stronger CTR on mobile Search |
| Promotion | Convey urgency and savings | eCommerce, retail, seasonal offers | Higher conversion rate during sale windows |
The right combination depends on what your buyer needs to see before clicking. A B2B SaaS account usually benefits most from sitelinks plus structured snippets plus lead form. A multi-location service business gets the largest lift from call plus location plus sitelinks. An eCommerce brand wins with image plus promotion plus sitelinks during sale periods.
A few rules that hold across industries:
Three patterns repeatedly erase the gains extensions should deliver. First, advertisers add assets once and never revisit them, leaving stale promotions and broken sitelinks live. Second, sitelinks point to generic homepages or category pages with no conversion path. Third, accounts enable every asset type without considering whether the audience actually uses them, which dilutes Google’s ability to learn what performs.
Treat extensions like a creative system, not a checkbox. Build a quarterly review into your PPC workflow, and benchmark CVR before and after every meaningful change. If you want a deeper foundation in PPC fundamentals before scaling, our breakdown on how to improve PPC ads with sitelink extensions walks through the structural setup in more detail.
One more pattern worth flagging: accounts that run extensions in isolation from the landing experience. If your sitelink promises “Transparent Pricing” but the destination page hides the price behind a form, you have just bought a click that will never convert. Audit every asset against the page it leads to, and either fix the landing page or change the asset. The cleanest accounts we see treat extensions and post-click experience as one connected funnel, not two separate teams.
Most accounts we audit have three to four extensions enabled when they should have eight. Closing that gap is rarely about more spend. It is about disciplined setup, clean reporting, and creative that matches what the searcher needs at the moment of intent. Our team builds asset libraries, runs asset-level experiments, and ties everything back to revenue inside your CRM.

If you are evaluating whether to fix this in-house or bring in a partner, start with a 30-day asset audit. Pull asset-level reports for your top three campaigns, identify which assets have zero impressions, and either rewrite or remove them. That single exercise often surfaces enough quick wins to fund the next quarter of testing.
Google rebranded ad extensions to “assets” in 2022, and the platform now uses the asset terminology across the interface and reporting. Most advertisers still use both terms interchangeably in conversation, and the function remains the same. Whether you call them extensions or assets, they are the additional pieces of information layered on your ad to lift visibility, click-through rate, and conversion outcomes.
Aim for at least four to six relevant asset types per campaign, layered across account, campaign, and ad group levels. Google only displays assets it predicts will improve performance, so adding more options gives the system room to test. Avoid forcing assets that do not match your funnel, such as image assets for a pure phone-lead business, because relevance still beats volume in Google’s selection logic.
Both, but through different mechanisms. Extensions lift CTR by expanding your ad’s footprint and showing more relevant information upfront. They lift conversion rate because users who clicked already saw qualifying signals such as price, location, or service categories. That pre-click qualification reduces bounce, raises post-click intent, and shortens the path from search to lead or sale, which compounds into stronger campaign ROI.
There is no universal winner because the answer depends on your funnel. Service businesses see the strongest gains from call assets and lead form assets. eCommerce brands convert best with image and promotion assets during sale windows. B2B advertisers usually get the highest incremental lift from sitelinks tied to pricing or demo pages combined with structured snippets that pre-qualify the click.
Yes. Performance Max relies heavily on assets including headlines, descriptions, images, videos, sitelinks, callouts, and structured snippets. The richer your asset group, the more channel combinations Google’s AI can test across Search, YouTube, Display, Gmail, and Maps. Asset-level reporting inside Performance Max now shows impressions, clicks, cost, and conversions, so you can prune weak assets and reinforce the ones driving measurable revenue.
Review assets monthly and refresh them at least once per quarter. Update promotion assets ahead of every sale window, swap out sitelinks tied to outdated pages, and rotate image assets when CTR declines. Stale assets fatigue quickly, especially in retail and seasonal categories. A quarterly refresh discipline, supported by asset-level performance data, keeps your account competitive against rising CPCs and shrinking organic SERP visibility.
