Industrial Tape Maker · Website + Digital Marketing
Coretech
We built the corporate website for Coretech, a manufacturer of industrial specialty tapes, and operate its digital marketing end to end — Google and Naver search ads, GA4 data analysis, and SEO.

Overview
Coretech manufactures and processes single- and double-sided industrial specialty tapes in-house, offering lamination, slitting, roll-cutting, and die-cutting as a one-stop service.
As the official Korean distributor for Germany's TESA and an official 3M dealer, it supplies tape solutions across electronics and appliances, automotive, construction and interiors, printing, and more.
To move beyond phone- and quote-driven industrial sales, we built a new corporate website (cttape.co.kr) that lets customers discover products online and convert into inquiries and orders.
Silmaril doesn't stop at the website — we continuously run the full digital marketing program: Google and Naver search ads, GA4-based data analysis, and SEO.
Role & Contributions
- Planned, designed, and built the corporate website (cttape.co.kr) — an information architecture with a product catalog, industry categories, cutting/processing guides, a resource library, and a support center
- Designed the conversion path from product/material search to product inquiry, tape sample requests, and electronic ordering
- Planned and ran Google Ads campaigns — keyword strategy, operations, and budget optimization
- Operated Naver search ad campaigns (Power Link and more) targeting industrial-tape keywords
- Built a measurement stack with GA4 and Google Tag Manager, analyzing traffic, search terms, and conversions
- Strengthened organic visibility on Naver and Google through SEO — metadata, structured data, and product/industry keyword content
- Acted as an ongoing operating partner, combining search-ad, organic-search, and GA4 data to keep improving the marketing
Key Work
Corporate Website Build
We built the site ourselves — from product/industry/processing guides to a resource library and support center — so industrial buyers find what they need fast.
Google Ads Operations
We run Google Ads campaigns for industrial-tape, TESA, and 3M keywords, optimizing budget against conversions.
Naver Search Ads
On Naver, where Korean B2B search concentrates, we run Power Link and other search ads to attract prospective accounts.
GA4 Data Analysis
With GA4 and GTM we measure acquisition paths, search terms, and inquiry/order conversions, distilled into reports that drive decisions.
SEO
We maintain metadata, structured data, and keyword content so products surface in organic search, not just paid.
Inquiry & Ordering Funnel
Product inquiry, tape sample requests, and electronic ordering for new and existing accounts are woven into the site's conversion flow.
Challenges & Solutions
Industrial Products Invisible in Search
- Situation
- Industrial tape is traded mostly by phone and quote, so Coretech's products barely surfaced in online search.
- Task
- Make Coretech visible the moment a prospective account searches.
- Action
- We claimed core keywords with Google and Naver search ads while strengthening organic visibility for product and industry keywords through SEO.
- Result
- By combining paid and organic search, we widened Coretech's points of exposure at the search stage.
Ad Budget Efficiency
- Situation
- In B2B industrial goods, keyword costs and inquiry value vary widely, so chasing impressions alone burns budget fast.
- Task
- Grow traffic that actually turns into inquiries and orders within a limited budget.
- Action
- Watching search-term reports and conversion data, we continuously adjusted keywords, creatives, and bids and pruned low-performing keywords.
- Result
- We established a model that allocates budget by inquiry/order conversion rather than raw impressions.
Data Instead of Gut Feel
- Situation
- There was previously no way to measure which channels and keywords actually led to inquiries.
- Task
- Be able to see and improve marketing performance with data.
- Action
- We built a measurement stack with GA4 and GTM tracking acquisition, search terms, and conversion events, and analyzed it regularly.
- Result
- We created a cycle that confirms which ads, keywords, and pages perform — and feeds that back into the next round of operations.
Tools & Stack
Impact
- Added a new touchpoint — organic search traffic — to industrial sales that ran on phone and quotes.
- One team runs search ads, organic search, and GA4 together, so the website and marketing don't drift apart.
- Established data-driven marketing that allocates budget and keywords by inquiry/order conversion, not impressions.
