Most link-building advice starts with a backlink database: export a competitor's links, filter the list, pitch the sites. It works, but slowly, because most of those links came from a relationship, a news moment or a paid placement that you cannot repeat. A site that published a competitor two years ago is not necessarily looking for writers today.
Sites that want contributors say so in public, on a page, in a handful of predictable phrases. Searching for those phrases next to your topic turns up the sites that are asking for submissions right now. This guide explains how that search technique works, which phrases to use, how to separate real publications from link farms, and how to run the whole search at once with the Backlink Finder, part of the SEO tools on Toolz.
TL;DR: To find sites that accept guest posts, search Google for your niche plus the phrases those sites publish, such as "write for us", "become a contributor" and "guest post guidelines". These phrases are called search footprints. The Backlink Finder runs six footprints at once, removes platforms like Reddit, Quora, Medium and Fiverr that match without accepting posts, keeps one row per domain with the page that matched, and exports CSV. It is free, no signup, with three searches a day. It does not judge site quality, so read every site before pitching, and follow Google's link spam policies.
What is a search footprint?
A search footprint is a phrase that a particular kind of web page reliably contains. Searching for the phrase filters the index down to that page type.
Guest post pages are an unusually clean example. A site that wants outside writers needs to tell them how to submit, so it publishes a page with a heading like "Write for Us" or "Contributor Guidelines". A site that does not want submissions has no reason to use those words. Put the phrase in quotes next to your topic and Google returns pages that are both about your topic and inviting contributions.
Footprints are not new or secret. Link builders have used them for as long as search operators have existed. What changes is which phrases to use, how to combine them, and how much cleanup the raw results need.
Which footprints find guest post opportunities?
The Backlink Finder runs these six queries. With "sustainable fashion" as the niche:
"sustainable fashion" "write for us"
"sustainable fashion" "guest post"
"sustainable fashion" "become a contributor"
"sustainable fashion" "guest post guidelines"
"sustainable fashion" "submit a guest post"
sustainable fashion intitle:"write for us"
Each finds a slightly different slice of sites.
| Footprint | What it tends to find | Notes |
|---|---|---|
| "write for us" | Dedicated contributor pages | The most common phrasing, and the largest result set |
| "guest post" | Guidelines pages and published guest posts | Broad; also matches articles labeled as guest posts |
| "become a contributor" | Larger publications with contributor programs | Often a formal application process |
| "guest post guidelines" | Sites with written submission rules | Usually well-organized editorial processes |
| "submit a guest post" | Pages with a submission form or email | Close to the pitch step |
| intitle:"write for us" | Pages whose title is the invitation | Filters out passing mentions in body text |
The niche is quoted in the first five queries so Google matches the exact phrase. The sixth leaves the niche unquoted and puts the footprint in intitle:, which requires the phrase in the page title rather than anywhere on the page. That catches sites whose contributor page title is exactly "Write for Us" but whose body text describes the topic in other words.
Other footprints exist, such as "contribute to", "accepting guest posts", "guest author" and "guest contributor". The six above cover the phrasing most sites use, and adding more mostly returns the same domains.
Why search footprints instead of a backlink database?
Footprints find intent. A backlink database finds history. Both have a place, but they answer different questions.
| Method | Answers | Strength | Weakness |
|---|---|---|---|
| Footprint search | Who is asking for contributors now? | Short path from list to published link | No quality or authority data |
| Competitor backlink analysis | Who has linked to similar sites? | Shows proven link sources | Many links are not repeatable |
| Broken link building | Which pages link to dead resources? | Offers the site a fix | Slow to find and qualify |
| Digital PR and data studies | Who will cite original research? | High-authority links | Expensive to produce |
| Unlinked brand mentions | Who mentions you without a link? | Easy ask, warm audience | Needs an existing brand |
A site with a live "write for us" page has already decided it wants submissions. That makes the first conversation easier than cold outreach to a site that has never published an outside writer.
How does the Backlink Finder clean the results?
Raw footprint results are messy. The same site appears under several queries, and platforms full of discussions about guest posting match the phrases constantly. The tool applies three cleanup steps.
Deduplicates by domain. Six footprints against one site can return six different pages of that site. They are one opportunity, so results are grouped by hostname (with a leading "www." ignored) and the first match is kept. Because queries are processed in the order listed above, a site that matches "write for us" keeps that page rather than a later match. Subdomains count as separate sites, so blog.example.com and example.com are listed separately.
Excludes platforms that never accept posts. Fifteen domains are removed outright, including any of their subdomains: google.com, youtube.com, facebook.com, pinterest.com, linkedin.com, twitter.com, x.com, instagram.com, reddit.com, quora.com, fiverr.com, upwork.com, amazon.com, medium.com and wikipedia.org. A Reddit thread discussing guest posting is not a site you can pitch, and a Fiverr gig selling guest posts is the opposite of what you want.
Keeps the page that matched. Each row shows the domain, the page title, a snippet and a Guidelines link to the exact page that carried the footprint. That page usually contains the submission rules, so you can qualify the site before writing to anyone.
Each query returns one page of up to ten Google results, so a search yields at most 60 results before deduplication. A broad niche typically ends with a few dozen distinct domains. If one of the six queries fails, the other five still return, so a single rejected operator does not cost you the whole search.
How do you tell a real publication from a link farm?
Read the site. A footprint search finds pages that carry the phrase, and some of those pages belong to sites that publish anything for a fee. Links from those sites carry risk, not value.
Google's spam policies on link spam name "large-scale article marketing or guest posting campaigns with keyword-rich anchor text links" as an example of link schemes that can hurt rankings. The problem is not guest posting itself. It is guest posting done at scale, for links, on sites that exist to sell them.
Use these checks on every domain before you pitch.
| Signal | Good sign | Warning sign |
|---|---|---|
| Topic focus | Most posts are about one subject area | Casinos, CBD, crypto and pet care on the same blog |
| Archive | Years of posts, regular schedule | A few months of posts, dozens per day |
| Authors | Named writers with bios and other work | "Admin" or anonymous guest authors on everything |
| Guidelines page | Editorial standards, topics wanted, word counts | A price list, or "dofollow links guaranteed" |
| Outbound links | Links that support the article | Several commercial anchor-text links per post |
| Audience | Comments, social shares, a newsletter | No sign anyone reads it |
| Disclosure | Clearly labeled sponsored content, if any | Paid posts presented as editorial |
If a site asks for payment to publish, the link should be qualified. Google's documentation on qualifying outbound links says paid links should carry rel="sponsored", and a site that promises otherwise is telling you something about how it treats Google's rules.
A worked outreach workflow
Here is a practical sequence from search to pitch, using the tool's output.
- Search a niche of two or three words. "Sustainable fashion" works better than "fashion" (too broad, too many generic lifestyle blogs) or "organic cotton baby clothes" (too narrow for footprints to match). Niches must be between 2 and 80 characters.
- Export the CSV. The download is named after your niche, for example
guest-post-sites-sustainable-fashion.csv, with columns for Domain, Title, URL and Snippet. Open it in a spreadsheet and add columns for Status, Contact, Pitch date and Notes. - Qualify each domain in five minutes. Open the Guidelines link, then the homepage and the latest few posts. Apply the checks in the table above. Mark each row keep, maybe or drop.
- Read the guidelines for the keepers. Note the topics wanted, word count, link policy and how to pitch. Many sites want a pitch with two or three headline ideas, not a finished article.
- Find angles. For each keeper, look for a gap in their archive that you can fill with real expertise. A pitch that names a specific missing topic gets more replies than a generic offer.
- Pitch, track and follow up once. Record the date in the spreadsheet. One polite follow-up after a week or two is normal; more than that is noise.
For finding the gap in step 5, the Ask Questions tool searches Reddit for recent questions about a topic, which often turns up exactly the article a niche site has not published yet.
What should the guest post itself link to?
One contextual link to a genuinely relevant page is normal and safe. Several keyword-stuffed links to money pages are the pattern Google's spam policies describe.
A good guest post link points at something that helps the reader of that article: a detailed guide, a free tool, original data. Use natural anchor text that describes the destination, and let the host decide how to mark the link. If the host marks it nofollow or sponsored, the article can still send readers and build your reputation with that audience.
It is also worth making sure the pages you link to are in good shape before the post goes live. A page with clear structured data is easier for search engines to understand, and a page that is missing from your XML sitemap can take longer to be discovered by crawlers than it should.
What are the limits of footprint searching?
Four limits are worth knowing before you rely on the list.
No quality scoring. The tool does not check domain authority, traffic, spam signals or whether a site is still active. Every qualification step is manual.
Only indexed phrases. A site that takes submissions through a form with no matching text, or calls its page "Pitch Us", will not appear. Sites that accept contributors privately by invitation never appear.
Results shift. Search results change as Google's index updates, so the same niche can return a slightly different list on different days.
Ten results per footprint. The tool reads the first page of results for each query. For a very large niche, running a few narrower sub-niches finds more sites than running the broad term repeatedly.
Is the search private, and are there limits?
The niche you type is sent to a Toolz server, which runs the six queries against a paid search API and returns the cleaned list. That is necessary, because the API key cannot be exposed in a browser. Nothing else about your session is sent for the search, and the page labels what it sends under the input.
Because every search costs six paid queries, each visitor gets three searches per day, resetting at midnight UTC. If you hit the limit, the page says so. The CSV export is built in your browser from the results already on screen, so exporting does not use a search.
When you are ready to build a prospect list, search for guest post sites in your niche, export the CSV, and qualify each domain against the checklist above before you write a single pitch.
