Case study: impact of backlinks on a LATAM e-commerce

Note: the data in this case study is anonymized and presented illustratively. The figures reflect the order of magnitude of real campaigns from our team — they are not reproducible nor a guarantee of results.

Documented cases with verifiable data are scarce in Spanish-language SEO literature. Most content about linkbuilding for e-commerce circulates as general claims, disconnected from real-world contexts. This article reconstructs a concrete intervention: a mid-sized e-commerce site with between 800 and 1,200 indexed URLs, operating primarily in Mexico with recent expansion into Colombia. The data covers a twelve-month period (March 2024 – February 2025) and was extracted from Google Search Console, Ahrefs, and the client's internal analytics platform.

For those who want to understand the broader industry context before diving into the case, the article Linkbuilding en el mercado LATAM: estado actual y desafíos offers an up-to-date overview of editorial ecosystem conditions in the region.

Site context and starting point

The site operates in the home décor and organization segment, with a catalog of approximately 340 active products. At the start of the intervention, the domain had a lean backlink profile: 47 referring domains according to Ahrefs, concentrated in low-quality directories and unlinked mentions in forums. The recorded Domain Rating (DR) was 18.

Monthly organic traffic estimated by Ahrefs was around 3,200 sessions, with a sustained decline over the six months prior to the project launch. The majority of traffic came from branded or navigational searches. Category pages — the most strategically important for capturing transactional demand — were ranking at average positions above 35 for their primary keywords.

The site had not suffered any documented manual or algorithmic penalties. According to the initial technical analysis, the visibility decline was the result of a combination of thin content on category pages, lack of domain authority, and growing competition from marketplaces with significantly stronger backlink profiles.

Diagnosis of the existing link profile

The analysis of the backlink profile at the starting point revealed three concrete problems:

• High concentration of exact-match brand anchors (over 70% of anchor texts pointed to the store name or the bare URL).
• A complete absence of links from media domains or publications specializing in décor, home, interior design, or lifestyle.
• Links coming from low-authority directories, some showing signs of private blog networks (PBNs), which represented a potential risk ahead of algorithmic updates.

This diagnosis drove two initial decisions: avoid aggressive disavow of existing links (the risk was manageable and the questionable domains represented a low volume), and focus the first quarter exclusively on building editorial authority from scratch.

Strategy implemented and execution phases

The campaign was divided into three four-month phases, each with distinct objectives.

Phase 1 (months 1–4): building the editorial foundation

The goal of the first phase was to establish a set of backlinks from domains with a DR above 30, verifiable topical relevance, and their own organic traffic. Three types of sites were prioritized: décor and interior design blogs with Spanish-speaking audiences, lifestyle portals with home sections, and general digital media outlets with trend supplements.

Fourteen articles were published on third-party sites during these four months. The content was not rewritten product descriptions: in every case, genuine editorial content was produced (organization guides, seasonal trends, material comparisons) that included the link in a contextual manner. The anchors used followed a varied distribution: 40% with descriptive category terms (e.g., "kitchen organizers," "home storage"), 35% with partial brand anchors, and 25% with generic or URL anchors.

For a deeper look at the rationale behind these proportions, the article Linkbuilding para e-commerce: estrategias según tipo de tienda explains in detail how to adapt anchor distribution based on the site's stage of development and catalog type.

Phase 2 (months 5–8): densification and geographic diversification

With the editorial foundation in place, the second phase targeted two simultaneous objectives: increasing the volume of referring domains and beginning to incorporate sites from the Colombian market, in line with the client's commercial expansion.

Twenty-two additional pieces were published, with a broader mix: regional news portals, media outlets specializing in e-commerce and consumer technology (covering the online shopping experience), and three collaborations with content creators who maintained their own blogs with strong authority profiles.

This phase introduced a practice that proved significant: publishing content in Colombian media that linked specifically to category pages, not to the homepage. This decision aimed to pass authority directly to the URLs with the greatest transactional potential. The results of this targeting shift are discussed later.

Phase 3 (months 9–12): consolidation and destination page optimization

The final phase combined linkbuilding with on-page work on the category pages that had gained positions but had not yet reached the first page. Eighteen additional pieces were published, focusing on higher-authority domains (DR 45+) and sites with audiences showing verified buyer profiles.

In parallel, the client's content team rewrote the introductions for the 12 most important categories, incorporating denser editorial content, structured FAQs, and UX best practices to facilitate conversion. This on-page intervention was outside the scope of the linkbuilding engagement, but its effect on the final results is inseparable and is explicitly noted in the analysis.

Data observed at the close of the period

By the end of the twelve months, the site's backlink profile had grown from 47 to 189 unique referring domains. The DR moved from 18 to 41. The following are the changes in visibility and behavior recorded by Google Search Console and the client's analytics platform.

Organic visibility

• Total monthly impressions in GSC went from 48,000 to 214,000 between the starting month and month 12.
• Category pages that began at average positions above 35 ended the period at an average position of 12.4 for their primary keywords.
• Four category URLs reached positions in the top five results for terms with monthly search volumes above 1,000 queries in Mexico.
• Organic traffic estimated by Ahrefs at the close of the period was 18,400 monthly sessions, compared to 3,200 at the starting point.

Sales behavior from the organic channel

The client shared aggregated conversion data segmented by channel. Sales attributed to the organic channel (last-click, based on the analytics platform configuration) showed 340% year-over-year growth. Two clarifications are necessary regarding this figure:

• The growth cannot be attributed exclusively to linkbuilding. The on-page improvements from month 8 onward, the addition of product reviews, and an email marketing campaign activated in month 6 all contributed to the conversion results.
• The last-click attribution model underestimates the role of informational searches at the start of the buyer journey. Some of the organic traffic that did not convert directly may have facilitated later conversions through other channels.

That said, the correlation between ranking gains on category pages and the increase in organic sessions with transactional intent is clear in the GSC data: queries including modifiers such as "buy," "price," or "shipping" grew consistently from month 5 onward, as positions began to consolidate.

Perfect attribution in SEO does not exist. What can be documented is the correlation between ranking gains on transactional pages and the increase in sessions with purchase intent, controlling for other variables to the extent the data allows.

Differences between the Mexican and Colombian markets

Performance in Colombia fell short of expectations. Category pages targeting the Colombian market gained positions in Google.com.co, but the additional traffic volume was proportionally lower than what was recorded in Mexico. Two factors explain this gap:

First, the number of publications in Colombian media was lower (9 out of 54 total), and their average DR was lower than that of the Mexican sites used. Second, and more significantly, several category pages were not localized for the Colombian market: they used terminology and price references in Mexican pesos, which increased the bounce rate.

This observation is consistent with what the general sector analysis documents in Linkbuilding en el mercado LATAM: estado actual y desafíos: backlinks from local domains have a greater impact when the destination pages are effectively localized for the target market's audience.

What worked and what did not

What had the greatest impact

• Publishing on sites with verified organic traffic. Domains with active organic traffic passed signals more quickly than domains with a good DR but stagnant traffic. In several cases, the link generated direct referral traffic before the SEO impact was visible.
• Linking to category pages, not the homepage. Links pointing directly to category URLs showed a more direct correlation with ranking improvements on those pages. Linking to the homepage concentrated authority in a node that was already relatively strong.
• Anchor diversity from the start. The decision not to rely on exact-match anchors avoided turbulence during the Helpful Content Update and core updates recorded during the period.
• Consistency in publishing cadence. There were no spikes in activity followed by extended pauses. The steady pace of 3 to 6 publications per month produced a gradual growth profile.

What did not produce the expected effect

• Collaborations with creators without independent blogs. Three of the Phase 2 collaborations were with creators who published primarily on social media and whose blogs were less than six months old. These links had no observable impact during the analyzed period.
• Content published on sites without consistent indexation. Two publications on small regional portals were never indexed by Google within the analysis period, leaving them outside the count of active referring domains.
• Insufficient localization of destination pages. As noted, performance in Colombia fell below its potential because the linkbuilding work was not accompanied by adequate on-page content localization.

Continuous measurement was decisive in detecting these inefficiencies early. For those looking to structure a monitoring system during an active campaign, Cómo medir el impacto real de una campaña de linkbuilding details the recommended indicators and review cadence.

Implications for other e-commerce campaigns in LATAM

This case is not representative of all e-commerce sites in the region or of all product segments. The conditions that make it comparable or not comparable to other projects must be evaluated on a case-by-case basis. That said, there are takeaways that hold validity beyond this specific client.
