Custom Links And Discounts Shopify Apps – Analytics & Insights

Affiliate Marketing ReferrLy holds the top spot for custom links and discounts with 35.7% market share, but the gap to challengers is closing, -19.0pp ahead of UpPromote Affiliate Marketing (54.8%). Affilitrak Affiliate Marketing sits at #3 with 6.0% share, rounding out the top tier. Together, the top 3 apps absorb 96.4% of all custom links and discounts installs — a highly concentrated landscape with limited room for new entrants. Yuko Affiliate Marketing is the standout mover this month, climbing 4 positions — a momentum signal worth tracking. Worth noting: the top-ranked app and the highest-share app aren't the same here — App Store rank and our market share metric (computed from review counts and other factors) move on independent dynamics, so cross-checking both views matters in this category.

Affiliate Marketing ReferrLy leads at 35.7%, only -19.0pp ahead of UpPromote Affiliate Marketing (54.8%), with rankings stable this month. When the top two custom links and discounts apps demonstrate similar real-world adoption, fit-for-store usually matters more than rank — comparing pricing model, integration depth, and support hours separates them better than the share gap does.

Affiliate Marketing ReferrLy climbed from #2 (May 2026) to #1 (Oct 2026) — a 1-position gain among custom links and discounts apps over the charted window. Across the top 5 plotted custom links and discounts apps, 4 improved their ranking while 1 declined — the category is moving upward overall. Affiliate Marketing ReferrLy's share held near 35.7% from May 2026 to Oct 2026 — a stable install base for custom links and discounts apps rather than active gain or loss.

Stable rankings across the top 5 plotted custom links and discounts apps mean merchants have largely settled on their preferences — challengers below the top 5 face an uphill path to break in.

United States dominates demand for custom links and discounts apps with 43.0% of all tracked installs — a single market that effectively defines the category's product priorities. United Kingdom follows at 8.8%, with Germany at 7.3%. Together, the top 3 markets account for 59.1% of custom links and discounts app installs worldwide. Canada (4.6%) and Australia (4.5%) round out the top 5.

With 43.0% of custom links and discounts app installs concentrated in United States, the leading apps in this category typically prioritize United States-based merchants for localization, currency, and support hours — merchants in United Kingdom (8.8%) and other regions sometimes find better fit in apps that over-index outside United States.

UpPromote Affiliate Marketing reached 1,000 reviews in 52 months since launch — the fastest ramp among the top 5 custom links and discounts apps tracked here. Affiliate Marketing ReferrLy crossed the same milestone in 64 months, 12 months behind.

3 apps on this chart haven't yet crossed 1,000 reviews: Shopify Collabs at 437, Affilitrak Affiliate Marketing at 264, impact.com Affiliate Marketing at 202 cumulative reviews. Shopify Collabs is closest to the milestone — its current count puts it roughly 44% of the way to 1,000.

The 12-month spread between UpPromote Affiliate Marketing and Affiliate Marketing ReferrLy reaching 1,000 reviews suggests a competitive custom links and discounts category — leaders pulled ahead by roughly a year, but no single app dominated launch-to-milestone speed. The ramp differences likely reflect both product quality and timing-of-launch rather than one clear category winner.
