Supplement PPC Case Study
How We Lifted Conversion Rate 54% for Supplement Spot

Digital Success improved Supplement Spot's conversion rate by 54% by restructuring its Google Ads account, pruning keywords, rewriting ad copy, building Google Shopping campaigns around customer purchase behavior, optimizing landing pages and adding retargeting.

The challenge: high ad spend, no return

Supplement Spot is well known for its anti-aging and natural health supplements, and its dietary, skin and beauty products are its strongest sellers online. The brand was running PPC campaigns and spending heavily, but the campaigns weren't delivering results. Transactions were coming in, but the return on investment wasn't there.

Our supplement PPC approach: study the products, then rebuild the campaigns

We started by studying Supplement Spot's whole product range, including its best sellers, and identified every area where the campaigns could improve.

The results

How to read the sections that follow. Each section carries a tag. Campaign evidence means activities and results documented in this engagement. Industry context and recommended practice are general guidance from Digital Success; they were not measured in this campaign and are not results. Illustrative examples are labeled as such and are not client data.

How Supplement Shoppers Search and Buy

INDUSTRY CONTEXT + ILLUSTRATIVE EXAMPLES (NOT SUPPLEMENT SPOT'S REPORTED KEYWORD SET)

Supplement shoppers search by need, by ingredient, by product type and by brand, and many compare options before buying. In paid search, those intents deserve different campaign structures. The formats below are illustrative; Supplement Spot's actual keywords and product groups were not published.

Documented in this campaign: the team analyzed customers' purchase behavior and niche to design the Google Shopping campaigns, ran Google and Bing paid search, and added retargeting. The case study does not publish the keyword or product-group structure.

Beyond Conversion Rate: Measuring Supplement PPC Profitability

CAMPAIGN EVIDENCE + RECOMMENDED PRACTICE

Supplement Spot's starting problem was a return problem, not a volume problem: transactions were coming in, but the return on investment was not. The reported result is a 54% improvement in conversion rate (indexed, 100 to 154), with transactions described as improved. Conversion rate is the right first lever for that situation, but it is not, by itself, proof of profitability.

Illustrative arithmetic, not a reported result. Cost per acquisition equals cost per click divided by conversion rate. If cost per click had stayed constant, a 54% higher conversion rate would cut cost per acquisition by about 35%. The case study does not report cost per click or spend, so the actual effect on acquisition cost cannot be confirmed from it.

Advertising Supplements: Claims, Policies and Landing Page Trust

INDUSTRY CONTEXT (NOT CAMPAIGN DATA; NOT LEGAL ADVICE)

Supplements are a closely scrutinized category. Ad platforms maintain policies that restrict certain health claims and ingredients, and U.S. regulators such as the FTC and FDA set expectations for how supplements are marketed, including substantiation for health-related claims. These rules change, so advertisers should check current Google Ads, Microsoft Advertising and regulatory guidance directly. The case study does not describe any compliance work.

What this means for supplement PPC management in practice:

• Write ads and landing pages within claims you can substantiate. Review copy against current platform policies before launch.
• Lead with concrete offers. The campaign featured discounts and offers prominently in ads (documented). An offer gives an ad something specific to promise that does not depend on a health claim.
• Build trust on the landing page. Clear ingredient information, shipping and return terms, and visible reviews, where available, support conversion for a category buyers approach carefully.

PPC and SEO Together: Using Paid Data to Guide Organic Growth

RECOMMENDED PRACTICE (NO ORGANIC SEARCH WORK IS DOCUMENTED IN THIS CAMPAIGN)

This engagement was paid media only. For ecommerce brands, though, paid search is a fast source of search-intent data that can also inform an organic strategy:

• Search term reports show the exact phrases behind converting clicks. Strong performers are candidates for category-page and content optimization.
• Shopping performance by product shows which products convert, indicating where product-page copy, reviews and structured data deserve investment.
• Landing page tests that lift paid conversion rate, like the landing page work documented here, can inform the design of organic landing pages.
• Paid search delivers controllable demand quickly; organic search builds visibility that compounds. Neither channel's long-term effect was measured in this case study.

Key takeaways for ecommerce PPC management

• Spend isn't the same as return. Transactions alone didn't mean the campaigns were profitable. The fix was structure, targeting and conversion optimization.
• Match campaigns to buyer behavior. Google Shopping campaigns were designed around how Supplement Spot's customers purchase.
• Fix the landing page, not just the ad. Conversion rate rose when the ad, offer and landing page worked together.

What This Case Study Does and Does Not Establish

This page documents what Digital Success did and the results reported above. It is not a controlled experiment, and some questions cannot be answered without data that was not published.

What the reported evidence supports

• Conversion rate improved by 54% following the campaign rebuild (indexed to the starting level = 100), and transactions improved.
• The rebuild covered account structure, keyword pruning, ad copy and offers, Google Shopping, Google and Bing paid search, retargeting and the landing page.

What it does not establish without additional data

• Absolute conversion rates, ad spend, revenue or the measurement period.
• Whether return on investment turned positive, or by how much. Return was the stated problem, but it is not quantified.
• Which change drove the gain: structure, copy, offers, Shopping, retargeting or the landing page.
• Any effect on organic search visibility. No organic work is documented.
