TuBack.linkHow it works
David TrotondaThe important question is not whether links matter. The good question is how they matter, what type of authority they help build and when that authority converts into real sales for an online store.
After reviewing official documentation of Google, the academic origin of PageRank and large SEO and ecommerce studies, the conclusion is quite clear: backlinks are not a magic button, but they are still one of the strongest external signals to compete in Google when a page already has useful content, correct intent and a store that converts.
This article explains the full chain: an external link helps discover, validate and contextualize a page; many good links from different domains increase perceived authority; authority helps to compete for better positions; the best positions receive many more clicks; and those clicks, if they reach a store with a good product and a good experience, become orders.
executive summary
The data does not say that any backlink will raise a store. They say something more interesting: pages and domains with more external authority tend to appear better in the results, especially in competitive searches. Google, furthermore, publicly acknowledges that references and links from prominent sites can be a signal of quality and trust.
For ecommerce, the economic impact appears when four variables are connected: average position, organic CTR, store conversion and average ticket. Going up from a low position to a high one can multiply clicks even if search demand does not change. If those clicks have a purchase intention, the growth in authority can end up being noticeable in sales.
| Piece | What the research shows | Reading for ecommerce |
|---|---|---|
| Links or references from prominent sites are a sign of quality and trust. | It is not enough to say that you are trustworthy: it is important that other relevant sites talk about your store. | |
| PageRank | The web can be understood as a graph where links convey importance. | Links are still a form of public reputation, although Google uses many more systems today. |
| Ahrefs | There is a correlation between referring domains, organic traffic and positioned keywords. | If you compete in categories with demand, a store without links usually starts at a disadvantage. |
| Backlinko | In 11.8M results, number 1 had on average 3.8x more backlinks than positions 2-10. | It's not pure causality, but it's a strong sign of how competitive SERPs behave. |
| CTR studies | Position 1 can capture a huge portion of clicks compared to lower positions. | Increasing ranking not only gives visibility: it changes the real volume of sessions. |
| Ecommerce benchmarks | The average ecommerce conversion usually moves around 2%-3%, with large differences by category. | More qualified organic traffic can translate into measurable orders. |
First: what does true authority mean?
In SEO there is a lot of talk about domain authority, Domain Rating, Domain Authority, URL Rating or Page Authority. These metrics are useful for comparing websites, but they are not an official counter within Google. Google does not enter Search Console and adds a little number called DR.
Real authority is broader: which external sites link to you, which sites mention you, whether those sites are relevant, whether the content around you makes sense, whether your brand appears consistently, and whether the landing page responds well to the search intent.
That is why a healthy strategy does not consist of buying just any link. It consists of creating a verifiable external presence: company profiles, ecommerce rankings, complete profiles, editorial mentions, guides, comparisons, real reviews, catalogues, marketplaces and content where it is natural to link your store.
| fake authority | royal authority | Practical decision |
|---|---|---|
| Lots of cheap links without context | Links from useful, relevant and trackable pages | Prioritize quality and consistency over volume. |
| Repeated exact anchors | Brand, canonical URL and natural mentions | Use store name and descriptive context. |
| Directories full of spam | Complete listings in places where a store makes sense | Choose platforms that allow you to explain products and trust. |
| Artificial rise of one metric | Better understanding of brand, category and reputation | Measure traffic, positions, conversion and sales. |
What Google officially says about links
The public documentation of Google does not reveal the complete algorithm, but it does leave important clues. In its explanation of how it determines rankings, Google says that its systems try to prioritize useful content and that one of the signals of quality may be that other prominent sites link or reference content.
Google Search Central also explains that search works in three phases: crawling, indexing and publishing results. Links especially help with discovery and context: Google finds URLs through known pages and then analyzes whether they deserve to be indexed and displayed.
The tricky part is that Google also has clear anti-spam policies. Trying to manipulate rankings with artificial links can cause loss of positions or exclusion. The correct reading for ecommerce is: look for real links, useful for users and with store context, not shortcuts.
- A good link helps discover a URL and associate it with an entity, a category and a brand.
- An external mention can boost trust if it comes from a relevant and prominent page.
- A link that is manipulated, hidden or created only to deceive the search engine enters the risk zone.
- Authority is no substitute for content, architecture, speed, product, pricing, or trust.
- The best strategy is to look like a real store because you are a real store, not to make weird prints.
PageRank: why Google was born looking at links
The original PageRank paper, published by Lawrence Page, Sergey Brin, Rajeev Motwani and Terry Winograd, raised a simple and powerful idea: the link on the web looks like an academic citation. If many pages link to a page, and some of those pages are also important, that page probably deserves more attention.
Google today is much more complex than the original PageRank. It uses machine learning, quality systems, semantic relevance, freshness, location, page experience and many other signals. But the underlying concept remains key: the web has a public structure of references, and that structure helps organize information.
For an ecommerce, this translates like this: you do not compete only with your internal content. You also compete with the external reputation that your domain has achieved. Two stores with similar products can have different results if one has mentions, listings, reviews, rankings and real links, and the other only exists within its own domain.
| Idea from PageRank | Ecommerce translation | Example |
|---|---|---|
| Links act as references | Other websites recognize that your store exists | An ecommerce ranking links your listing. |
| Not all links are worth the same | It matters who links and in what context | A complete card does not weigh the same as a lost comment. |
| The importance is distributed throughout the graph | A strong domain can help internal pages | The home page receives links and transmits authority to categories. |
| Context also matters | The relevance of the linking site affects the interpretation | Fashion linked from a fashion guide makes sense. |
Large studies: links and rankings go together
SEO studies cannot demonstrate the internal algorithm of Google. Normally they are correlation studies: they look at millions of results and observe which factors appear most frequently in high positions. This does not prove absolute causality, but it does allow useful patterns to be detected.
Ahrefs analyzed billions of pages and found that 96.55% were not receiving estimated organic traffic from Google. In their analysis, one of the main reasons was the lack of backlinks, and the study shows a clear correlation between referring domains, organic traffic and the number of ranked keywords.
Backlinko, with the help of data from Ahrefs, analyzed 11.8 million results from Google. Their summary indicates that global domain authority correlates with higher rankings, that pages with more backlinks tend to rank above those with fewer, and that result number 1 had on average 3.8 times more backlinks than results 2 to 10.
The honest read is this: the links don't explain everything. But when a search is competitive, it is very difficult for a new page, without external authority and without a recognizable brand, to displace competitors who have been accumulating references for years.
| Study | Relevant information | Be careful when interpreting it |
|---|---|---|
| Ahrefs Search Traffic Study | 96.55% of pages without estimated organic traffic. | Not everything is about links: demand and intention also influence. |
| Ahrefs | Pages with more referring domains tend to have more traffic and more keywords. | Correlation does not mean that any link causes rise. |
| Backlinko 11.8M SERPs | Number 1 had on average 3.8x more backlinks than positions 2-10. | Strong sites also tend to have better content and branding. |
| Backlinko | The diversity of reference domains seems important. | Better 10 real domains than 100 worthless links from the same site. |
From positions to clicks: this is where the money starts
Moving up positions matters because the distribution of clicks in Google is not linear. Going from position 10 to 8 can help, but going from 5 to 2 or from 3 to 1 can completely change the volume of visits.
First Page Sage, in its meta-analysis of CTR, estimates for classic organic results a 39.8% CTR in position 1, 18.7% in position 2, 10.2% in position 3, 5.1% in position 5 and 1.6% in position 10. Sistrix, with another methodology, found that the first organic result mobile captured 28.5% of clicks on average, and the CTR changes a lot depending on the type of SERP.
Advanced Web Ranking maintains monthly CTR benchmarks with millions of keywords and allows segmentation by device, country and industry. The important idea is not to memorize an exact number, but to understand that the position brutally modifies the available clicks.
| Position Google | Indicative CTR First Page Sage | Visits with 10,000 searches/month |
|---|---|---|
| 1 | 39.8% | 3,980 visits |
| 2 | 18.7% | 1,870 visits |
| 3 | 10.2% | 1,020 visits |
| 5 | 5.1% | 510 visits |
| 8 | 2.1% | 210 visits |
| 10 | 1.6% | 160 visits |
Numerical example: from authority to sales
Imagine a natural cosmetics store that wants to position a category for a search with 10,000 monthly searches. Now it is in position 8. With an indicative CTR of 2.1%, it receives about 210 visits per month from that keyword.
After improving content, product, structured data and getting relevant links from listings, rankings, blogs and category mentions, it rises to position 3. With an indicative CTR of 10.2%, it would increase to about 1,020 visits per month. The difference would be 810 additional monthly visits just for that search.
If the store converts at 2.74%, which is the global benchmark that Dynamic Yield shows for ecommerce on its conversion rate page, those 810 extra visits could generate about 22 additional purchases. With an average ticket of 60 euros, we are talking about 1,320 euros extra per month. If the category scales to several keywords, the figure is multiplied.
| variable | Before | After |
|---|---|---|
| Position | 8 | 3 |
| Estimated CTR | 2.1% | 10.2% |
| Monthly searches | 10,000 | 10,000 |
| Organic visits | 210 | 1,020 |
| Extra visits | - | 810 |
| Ecommerce conversion | 2.74% | 2.74% |
| Extra orders | - | 22 approx. |
| Average ticket | 60 euros | 60 euros |
| Extra income | - | 1,320 euros/month approx. |
Why this works especially well in ecommerce
In ecommerce, many searches have a clear commercial intention: buy vegan sneakers, natural cosmetics for sensitive skin, Nordic lamps, hypoallergenic dog food, personalized gifts for couples. When a store positions on these queries, the user is not reading out of pure curiosity: he is comparing, evaluating or close to buying.
Wolfgang Digital, in its Online Retail Report, shows that organic continues to contribute a relevant part of ecommerce revenue: in its retail sample, organic search represented 23% of revenue, while paid search dominated with 36%. Its reading is clear: the organic no longer lives alone, but it continues to be a critical part of a combined strategy to not depend totally on ads.
The advantage of organic authority is that it accumulates. An ad stops working when you stop paying. A well-positioned category can continue bringing visits as long as it maintains relevance, product, stock, experience and external authority.
| Channel | Advantage | Risk |
|---|---|---|
| Organic SEO | It can accumulate traffic and reduce payment dependency. | It takes time and needs authority, content and technique. |
| Paid search | It scales quickly and allows you to control keywords. | Depends on budget and increasing CPC. |
| Referral/backlinks | It can bring authority, referral traffic and trust. | If forced, it may look like spam. |
| Email/retention | Converts well on its own audience. | You need to capture the demand first. |
Not all links sell the same
A link can help in three ways: SEO authority, referral traffic and brand trust. The best backlink for ecommerce is the one that combines at least two of these layers.
For example, a listing in an ecommerce ranking can convey authority and also explain what the store sells. A business profile can reinforce entity even if it does not send many direct sales. An editorial review can bring qualified buyers. A directory without context, on the other hand, can contribute very little even if it has a high metric.
| Link type | SEO Authority | Referred traffic | Trust/entity |
|---|---|---|---|
| Ecommerce ranking sheet | High if the page is indexable and relevant | Medium | High |
| Royal editorial review | High | High | High |
| Complete social profile | Medium | Medium | High |
| Marketplace or catalog | Medium | High if there is demand | High |
| Empty generic directory | Low or uncertain | Low | Low |
| Spam comment | Risk | Low | Negative |
Domain authority also helps new pages
A store with accumulated authority not only positions the home better. You can also launch new categories, guides or products more easily because the domain already has external links and an internal structure that distributes authority.
Ahrefs explains this when talking about pages without backlinks that still receive traffic: many belong to strong domains that can transfer PageRank internally. For ecommerce this is key: if your home, your main tabs and your categories receive links, the new pages do not start from absolute scratch.
The practical consequence is that you should not only chase links to the home page. You need an architecture that allows you to distribute authority towards profitable categories: sustainable fashion, natural cosmetics, dining room furniture, dog food, personalized gifts or whatever your store sells.
- Get brand links to the home page to consolidate your entity.
- Get contextual links to categories when external content talks about that category.
- Links internally from guides and sheets to collections with margin and demand.
- Avoid creating hundreds of fine categories without demand or internal links.
- Measure which pages receive links and which pages generate income.
The practical formula to calculate SEO ROI
The ROI of building authority should not be sold as faith. It can be modeled. You will not know the exact result before working, but you can estimate scenarios.
The simple formula is: monthly searches per expected CTR per conversion per average ticket. Then you subtract the cost of content, tools, creation of files, outreach and maintenance.
Example: if five commercial keywords add up to 30,000 monthly searches, going from an average CTR of 2% to 6% means going from 600 visits to 1,800 visits. That's 1,200 extra visits. With a 2.5% conversion and a ticket of 55 euros, that's 30 orders and 1,650 euros per month. If authority work costs 900 euros per month for six months, you need to look at the cumulative ROI, not just the first month.
| Step | Formula | Example |
|---|---|---|
| Current traffic | Searches x current CTR | 30,000 x 2% = 600 visits |
| Target traffic | Searches x target CTR | 30,000 x 6% = 1,800 visits |
| Increase | Goal - current | 1,200 extra visits |
| Extra orders | Extra visits x conversion | 1,200 x 2.5% = 30 orders |
| Extra income | Orders x average ticket | 30 x 55 euros = 1,650 euros |
| ROI | (Revenue extra - cost) / cost | Depends on margin and time horizon |
How to build links without getting into trouble
The sure way to build authority is for each link to have a human reason. If someone comes to that page, they should understand why your store appears there. If there is no editorial, commercial or informative reason, it is probably not worth it.
For ecommerce, the first links should be of basic presence and trust: Google Business Profile if applicable, Merchant Center Free Listings, Facebook Business, Instagram, TikTok, LinkedIn, YouTube, Apple Business Connect, Bing Places, ecommerce rankings, brand listings, marketplaces and real vertical directories.
Next comes the most powerful part: content and relationships. Honest reviews, category guides, comparisons, collaborations with creators, mentions in blogs, downloadable resources, own studies and rankings where the store appears with context.
| Phase | Objective | Examples |
|---|---|---|
| Base | Let Google understand the entity | Business profiles, official networks, ecommerce file. |
| Catalog | Let Google understand products | Merchant Center, product schema, marketplaces. |
| Relevance | That the store fits into a category | Fashion, beauty, home, food, B2B directories. |
| Editorial authority | Let others speak about the store with discretion | Reviews, guides, studies, comparisons. |
| Trust | That the user dares to buy | Real opinions, clear policies, verifiable mentions. |
Measurement: what to look for in Search Console and Analytics
Don't measure authority only with DR or DA. These metrics help, but the business is looked at with its own data: impressions, average position, CTR, clicks, organic sessions, organic revenue, landing conversion and assisted conversion.
The good pattern is usually seen in phases. First, they increase tracking and impressions. Afterwards, some keywords go from positions 30-50 to 10-20. Then they enter the top 10. When they enter the top 3, clicks can grow strongly. Finally, if the page has good intentions and good experience, orders arrive.
You also have to look at quality. If clicks increase but not sales, it may be that the keyword is informative, that the landing does not match the intention, that the price does not compete or that the product sheet does not generate trust.
| Metric | Where to see it | What does it mean |
|---|---|---|
| Impressions | Google Search Console | Google now shows your pages more. |
| CTR | Google Search Console | Your snippet and position attract clicks. |
| middle position | Google Search Console | You are getting closer to the top 10 or top 3. |
| Organic sessions | GA4 or analytics | The clicks reach the store. |
| organic conversion | GA4/ecommerce | Traffic buys or generates leads. |
| Organic revenue | GA4/ecommerce | Authority translates into money. |
| Referring domains | Ahrefs/Semrush/Search Console | External reputation grows. |
Checklist of backlinks that contribute the most to ecommerce
If a store starts from scratch, it wouldn't start with a hundred weird links. I would start with the links that help Google and users verify that the brand exists, that it sells real products, and that it belongs to a specific category.
- Complete business file with name, category, logo, URL and consistent data.
- Google Merchant Center Free Listings for physical products and clean feed.
- Official social profiles with coherent bio and canonical link.
- LinkedIn Company Page if there is a company, team or B2B.
- File in ranking/ecommerce directory where the store is explained in detail.
- Marketplaces or catalogs that fit the type of product.
- Vertical directories by category: fashion, beauty, home, food, technology or industrial.
- Editorial reviews and buying guides with real context.
- Own linkable content: studies, comparisons, calculators, templates or rankings.
- Internal links from guides to categories with demand and margin.
Fonts used and how to read them
The research mixes official sources, academic papers, SEO correlation studies and ecommerce benchmarks. The correct way to read them is together: Google explains the framework, PageRank explains the origin, Ahrefs and Backlinko show patterns, CTR studies quantify the value of moving up positions and ecommerce benchmarks convert traffic into estimated sales.
No source can promise that a specific link will raise a specific position. What they do allow us to say is that external authority continues to be a key piece to compete, and that in ecommerce that competition has an economic impact when the store converts.

Conclusion
Backlinks are not magic, but they are not decoration either. They are a public form of reputation. When they come from relevant sites, with context and with a real reason to link, they help Google to better discover, understand and value a store.
Authority alone does not sell. It sells when it pushes correct pages to better positions, those positions attract clicks, the clicks have commercial intent and the store converts. That is the complete chain that an ecommerce must measure.
That's why modern link building should not be a list of URLs. It should be an authority plan: first entity, then catalog, then category relevance, then editorial mentions and always measurement of positions, clicks and sales.
