Backlink Search: A Prospecting Workflow That Finds Links

Quick answer: A backlink search is outward-facing research: you are looking for pages that could plausibly link to you, not auditing the links you already have. It runs across five surfaces, meaning competitor profiles, search operators, the local media and association layer, your own existing relationships, and unlinked mentions of your brand.

Most people who search for this are handed a tool review, which answers a different question. Checking is inward-facing: what do I have, is it still there, is any of it a problem. Searching is outward-facing: who could link to me, why would they, and who do I contact. The second is a research discipline with a repeatable process, and the tool is a small part of it. This post is that process, written for someone doing the work in Singapore, where the surface being searched is unusually small and saturates faster than any guide written from a large market will warn you. It does not cover how indexes are built, what the free tiers withhold, or how to read any particular product, which are separate subjects. Our SEO services page covers the commercial framing.

Surface One: Competitor Link Profiles

The obvious starting point, and the one that runs out fastest.

Pick real competitors, not aspirational ones. The businesses you actually lose deals to, at your size, in your city. Profiles of national brands and regional players will fill your sheet with sources you cannot reach.

Work at domain level and sort by reachability, not by score. Open each domain and ask one question: could a business like mine plausibly appear here. Association member lists, supplier and stockist pages, curated directories, local publications and event organisers all pass. Research papers, personal blogs of individuals in another country and pages behind a paywall do not.

Run the intersect. Domains linking to two or more competitors but not to you. Those are the sources with a demonstrated willingness to link to businesses in your category, which is the single strongest qualifying signal available at this stage.

Then look at the differences, not just the overlaps. A domain linking to exactly one competitor is often a relationship rather than a category pattern, and relationships are sometimes reproducible. A distributor page, a client case study, a speaking engagement.

Expect saturation, and plan for it. In a local niche, the same association, the same two trade publications and the same three directories will recur across every competitor. We have generally found this surface exhausted within three to five weeks of serious work, after which it returns almost nothing new. That is not a failure of method, it is the size of the market, and the response is to move to the surfaces below rather than to keep re-running the report. This is why we scope prospecting as a front-loaded research phase rather than an indefinite monthly line, and it sits inside our SEO audit and consulting work.

Surface Two: Search Operators on the Open Web

This is the surface most people skip and the one that keeps producing after competitor profiles dry up. You are querying the live web rather than a third-party index, which means you can find pages no crawler has prioritised.

Useful patterns, adapted to Singapore. Replace the bracketed parts.

• site:.sg "member directory" [your sector]
• site:.sg "our members" OR "member list" [trade term]
• site:.edu.sg "industry partners" OR "industry advisory"
• site:.gov.sg "useful links" OR "related links" [sector]
• site:.sg intitle:"resources" [sector term]
• "singapore" "[sector]" "recommended suppliers"
• site:.sg "write for us" OR "contribute" [sector]
• site:.sg "sponsors" [event type] 2026
• site:.sg "preferred partner" OR "authorised dealer" [brand you stock]
• "[your brand]" -site:[yourdomain].com to surface unlinked mentions
• site:.sg "[competitor brand]" -site:[competitordomain].com to find who talks about them

Two disciplines make this productive. First, search the language your sector actually uses, including local terms and abbreviations, because a directory built for the trade will use the trade’s words. Second, vary the country signal: .sg catches a lot but plenty of Singapore organisations sit on .com, so repeat the better-performing queries with "singapore" as a phrase instead of the domain restriction.

A note on the contributor searches. Looking for publications that openly accept contributions is legitimate research, and writing something genuinely useful for a trade publication is ordinary professional practice. Paying a fee for a placement is a different transaction entirely and it breaches Google’s link spam policies. If a site’s contributor page leads to a rate card, that is a marketplace rather than a publication, and it belongs in the discard column.

Surface Three: The Local Media and Institution Layer

In Singapore this surface is small enough to enumerate rather than search, which is a genuine advantage and almost nobody uses it.

Build the list once, by hand. The national and business press titles. The trade and sector publications relevant to you, which is usually between two and six. The statutory boards and agencies whose remit touches your sector. The chambers of commerce and bilateral business councils. The professional bodies and trade associations, including the ones you are not yet a member of. The polytechnics and universities with departments related to your field. The event and awards organisers in your sector. The genuinely curated local directories, which is a short list.

That document is an asset and it does not expire quickly. It took us an afternoon per sector to build the first versions and they have needed only light maintenance since. A tool cannot generate it because half of these pages are crawled rarely and rank for nothing.

Then work it as a relationship list, not a link list. For each entry, write down what would have to be true for them to mention you: a data point they need, a comment on a regulatory change, a member profile, a sponsorship, a panel seat, a student project. That column is the actual work. In contracting and trades, the association and supplier layer dominates almost everything else, which is the pattern behind our contractor SEO work.

Those sectors are also where the institution list pays back fastest, because licensing bodies, materials suppliers and project owners all maintain pages that link out as a matter of routine. Our contractor results write-up shows the groundwork that comes first, from an unclaimed Google Business Profile to 29 reviews and 18 monthly enquiries.

Surface Four: Relationships You Already Have

The highest-conversion prospecting available and consistently the last place anyone looks.

Suppliers, distributors and brands you stock. Many maintain dealer, stockist or partner pages. If you are not on it, ask. If you are on it without a link, ask for the link.

Software and platform certifications. Partner directories exist for most of them and are usually a form submission.

Clients and customers. When a project has gone well, the other party is frequently happy to be named or to publish a short case study of their own.

Professional bodies and memberships you already pay for. Complete the profile, include the URL, and check it annually. Redesigns remove these silently.

Landlords, malls, business parks and coworking operators. Tenant directories are real pages that link out.

Event participation you have already done. Past speaking slots, panels and sponsorships often have archived pages still carrying links, or missing them.

Suppliers you refer work to, and who refer to you. A mutual page is a normal commercial artefact when the relationship is real.

Run this as a stocktake before any outreach campaign. On most accounts we review there are several of these sitting unclaimed, and recovering them takes hours rather than months. For businesses selling online, the stockist and marketplace layer behaves differently again, which is covered on our e-commerce SEO services in Singapore page.

Surface Five: Unlinked Mentions

Someone has already decided you are worth naming. Asking them to link is the shortest path in the discipline.

Find them with brand searches, excluding your own domain, and repeat for common misspellings, your founders’ names, your product names and any former trading name.

Set up monitoring so future mentions surface within days rather than being discovered a year later.

Ask simply. A two-line email to the person who wrote the piece, thanking them and asking whether they would mind linking the mention, converts well because the editorial judgement has already been made.

Include the awkward ones. Forum threads, LinkedIn articles, association newsletters and event recaps all count, and several will be nofollow, which does not make them worthless.

Qualifying What You Find

A list of two hundred unqualified domains is worse than a list of fifteen qualified ones, because the unqualified list invites volume outreach and volume outreach is how businesses end up on the wrong side of the policies. Score each candidate out of ten.

A candidate scoring 7 or above goes into active outreach. Between 4 and 6, park it and revisit if you develop a stronger reason to be there. Below 4, discard and do not revisit. Anything with a price list attached to link placement is a discard regardless of what else it scores, because the transaction rather than the site is the problem.

One deliberate omission from that rubric: the vendor authority score. We leave it out because it changes the ordering in the wrong direction. High-scoring directories with no standards float to the top, and small, genuinely read local publications sink. Reading the page for twenty seconds beats the metric consistently, and in a market where the whole candidate list is countable, you can afford to read every one.

The Cadence That Actually Works in a Small Market

Front-load the research. Two to three weeks of concentrated searching across all five surfaces produces a prospect sheet that will keep a programme fed for months. Spreading the same work thinly across a year produces a worse list slowly.

Then switch to a maintenance rhythm. Roughly two hours a month: check unlinked mentions, revisit the parked candidates, re-run one or two operator queries, and add anything new from the institution list.

Volume expectations should be modest and are not a failure. In a local niche, a programme adding one to three genuinely good referring domains a month is doing well. Anyone promising ten a month at a fixed fee is describing a supply they control, and a controlled supply of links is a purchased one.

Record enough to be useful. Domain, the specific page, the named contact, the score, the reason they would mention you, the date contacted, the outcome, and the date to follow up. Without the reason column the sheet becomes a mailing list, and mailing lists get ignored.

Our interior design case study shows why assets a business already holds deserve attention before cold prospects. The 4-person firm already had Qanvast and RenoTalk profiles and a Google Business Profile whose earlier verification attempt had failed and lapsed. Rather than starting with new targets, the GBP was verified and rebuilt with 60 project photos, and the platform profiles were optimised with consistent branding, an updated portfolio and review management. Over 5 months, alongside new style and project pages, GBP reviews grew from 6 to 34 and organic project enquiries from 7 to 22 a month. Existing relationships cost nothing to find.

The Searches That Waste Time

Sorting by authority score and working down. Produces a list of high-metric, low-standard directories.

Scraping thousands of domains for a mail merge. Low response, reputational cost, and it selects for the sites that accept anything.

Chasing national press before you have anything reportable. Journalists need a story. Build the data or the position first.

Re-running competitor intersect monthly after it has saturated. In this market it stops producing within about a month. Three of the same eleven names is not new information.

Filtering out nofollow prospects. Removes several of the best local publications from consideration for a reason that barely matters.

Pursuing global sites with no Singapore connection. Weak relevance, low conversion, and your buyers are not there. The counterexample worth naming: where a business genuinely serves regional clients, the surface widens and the arithmetic changes, and that is a real strategic decision rather than a prospecting one. It shapes how we approach accounts like the ones on our car dealer SEO page.

Project-based businesses sit in between, because a single completed job can produce a citable story on a client site, a supplier site and an industry publication at once. Our interior design results write-up shows the on-site half of that, with project pages built for the firm’s 12 best past projects.

Field notes: Our B2B ecommerce case study shows what a finished prospect list looks like when it is built around the buyer’s industry rather than a tool’s output. For the wholesale kitchenware supplier in Ubi, the link sources were the Singapore Business Federation directory, the Enterprise Singapore supplier registry, HardwareZone Business and 12 industry-specific trade directories covering F&B, hospitality and food manufacturing. Every one of them is a place a procurement manager might actually start a supplier search, so each placement doubled as a route to buyers as well as a link. The submissions ran from Month 4 to Month 8, after 14 category pages and 6 industry vertical pages had been built to give those links somewhere worth landing. Over the 8 months, Domain Authority went from 11 to 22 and monthly organic trade enquiries from 5 to 28, results of the full programme of architecture, content, schema and directory work rather than the links alone. The real effort goes into deciding which sources belong on the list in the first place; once that research is done, the outreach itself is the easy part.

Our Take

A backlink search is research, and it should be resourced like research: concentrated, front-loaded, documented, and done by someone who will read the pages rather than sort the spreadsheet. The tool contributes one of five surfaces and it is the one that runs out first.

The trade-off worth resolving rather than leaving open: front-loading the research costs you two or three weeks before a single email goes out, which feels slow when a client is waiting to see activity. Resolve it by looking at what the alternative produces. Prospecting drip-fed alongside outreach reliably produces a thinner list, more cold sends, lower conversion and a programme that mistakes email volume for progress. Three weeks of proper searching in a market this small can cover a year of work.

Most agencies begin prospecting with a competitor intersect report because it is fast and it fills a slide. In Singapore it is also the surface that saturates first, usually inside a month, and a programme that has not built the other four surfaces by then has nowhere to go but colder and worse. Start with the relationships you have already earned, build the institution list by hand because no tool will, and treat the operator searches as the engine that keeps running after the report stops. Then qualify by reading. Expectations differ substantially by sector, which is why we plan this per vertical across our industry work rather than as a universal monthly target.

What a properly resourced research phase costs, and how it separates from the ongoing outreach it feeds, is set out on our pricing page.

For a team of two or three people the honest version is narrower again: do the relationship stocktake, build the institution list once, and accept a slower cadence rather than buying volume. That scope is on our small business SEO page.

We treat backlink search as active research rather than a report to pull, and in our experience the prospects worth pursuing rarely show up in a standard competitor-gap export. Our team manually reads the surfaces this guide describes for every client campaign, because a site that looks relevant on paper often turns out, on a five-minute read, to be the wrong fit entirely.

Frequently Asked Questions

What is the difference between a backlink search and a backlink check?

Direction. A check looks inward at the links you already have: do they exist, are they still live, is anything among them a problem. A search looks outward at pages that could link to you but currently do not. They use some of the same tools and answer completely different questions, and conflating them is why so many prospecting exercises turn into audits that produce no new opportunities.

Which search operators are most productive in Singapore?

The ones targeting member lists and partner pages, because those are the sources with a demonstrated habit of linking to businesses in a category. Combining a site:.sg restriction with phrases such as “member directory”, “our members”, “industry partners”, “preferred partner” and “authorised dealer” is consistently the most productive pattern. Repeat the better queries with “singapore” as a phrase instead of the domain restriction, because plenty of local organisations sit on a .com.

How long should prospecting take before outreach starts?

Two to three weeks of concentrated work for a single sector in a market this size, covering all five surfaces. That will typically produce enough qualified candidates to feed a year of outreach. Starting outreach on day two with a thin list feels faster and produces worse results, because the first emails go to the least qualified prospects and teach you nothing except that cold sends do not convert.

How many new referring domains is realistic per month?

One to three genuinely good ones in a local niche, and that is a programme working properly rather than one underperforming. The available pool is small and the valuable sources require something real from the business. Anyone offering a guaranteed ten a month at a fixed fee is describing a supply they can control, and a controlled supply of links is a purchased one, which breaches Google’s link spam policies.

Should I contact the generic company email address?

Only as a last resort, and note that a missing named contact is itself a scoring signal. Find the person: the editor of the relevant section, the association’s membership officer, the communications lead, the person who wrote the piece that mentioned you. Response rates to a named individual with a specific and short request are not comparable to a generic inbox, and in a market where the whole candidate list is countable, spending ten minutes finding the right person is a rational use of the time.

Is guest posting still worth pursuing?

Contributing genuinely useful writing to a publication your market reads has always been legitimate and still works, particularly with the trade titles, which need material and are reachable. The thing to avoid is the marketplace version, where a fee buys a placement on a site with no real audience. The test is simple and does not require judgement: if the contributor page leads to a price list, it is a marketplace, and it goes in the discard column.

What do I do when competitor intersect stops producing names?

Treat it as the expected end of that surface rather than a problem, and move to the other four. In our experience that happens within about a month of serious work in a local niche. The operator searches keep producing, the hand-built institution list keeps producing, and the relationship stocktake usually has rows nobody has claimed. The deeper shift is that the question changes from who links to my competitors into what would make a local publication want to mention me, which is editorial work rather than search work.

Should I use authority scores to prioritise prospects?

Not as the primary sort. Vendor scores consistently promote high-metric directories with no editorial standards and demote small local publications your buyers genuinely read, so the ordering they produce runs against commercial value. Use relevance, audience reality, editorial standards, reachability and Singapore specificity, and read the page before scoring it. In a market where the candidate list runs to dozens rather than thousands, reading every one is affordable.

How do I find unlinked mentions of my business?

Search your brand name while excluding your own domain, and repeat for common misspellings, founder names, product names and any previous trading name. Then set up ongoing monitoring so future mentions surface within days. These convert better than any other category of prospect because the editorial decision has already gone your way, and the request is small: a two-line email to the author asking whether they would mind linking the mention.

Can I outsource the searching and keep the outreach in house?

You can, and it is often a sensible split, but the handover needs the reason column filled in. A list of domains and scores with no note of why each one would plausibly mention your business is a mailing list, and whoever does the outreach will default to a template. Insist that every row carries the specific hook: the data they need, the membership they offer, the partner page you qualify for, the article that already names you.
