🔍 Competitor analysis in the guest posting market: how and why

Competitor analysis in guest posting is reverse engineering their link strategy: you figure out which platforms they publish on, which links they get, and where their weak spots are, then use that to overtake them faster and cheaper. The goal is not to copy someone else's profile, but to find platforms competitors haven't reached yet and close the link gap. Below we'll walk through step by step how to find your real rivals, break down their donors, and turn that data into a list of platforms for your own publications.

💡 Quick overview: how to run competitor analysis

• Identify your real competitors in search results, not just in business.
• Pull their link profiles in Ahrefs, Semrush, or Moz.
• Find the link gap: donors that link to competitors but not to you.
• Evaluate each platform by relevance, traffic, and openness to guest posts.
• Build your own priority list instead of blindly copying someone else's.

Why look at competitors at all

Links still decide who ends up at the top of search results, and most sites don't take advantage of that. According to Backlinko, in a 2025 study about 95% of all pages on the internet have zero backlinks. That means simply having quality links already sets you apart from the vast majority, and competitor analysis shows you the shortest path to those links.

The cost of inaction is also visible in traffic. According to Ahrefs, based on a 2023 study, 96.55% of all pages get no traffic from Google at all. Most often the reason isn't the content, but the fact that nobody links to the page and search engines don't consider it authoritative. Competitor analysis helps you understand where others get their authority from, so you don't have to invent a strategy from scratch.

Finally, competitors save you time. Instead of randomly searching for guest post platforms, you get a ready-made list of sites that have already accepted your rivals' content. That immediately cuts out dead and irrelevant sites and leaves you with proven entry points. Essentially, your rivals have already done part of the field reconnaissance for you, and it would be a shame not to use that to start not from a blank slate, but from a tested base of platforms.

Step 1: find your real competitors

The biggest mistake at the very start is confusing business competitors with search competitors. Your market neighbor may not do content at all, while traffic on your topics is being taken by a blog you never thought about. That's why competitors are defined by search results: enter the key queries in your niche and see who consistently holds the top positions.

Put together a list of five to seven sites that regularly appear for your topics. Those are the link profiles you'll be analyzing. It helps to split them into two groups: direct competitors at your level and stronger platforms worth aspiring to. The first group shows achievable goals, the second sets the direction for growth.

Don't limit yourself to one search engine and one region. Sometimes a strong niche competitor is only visible in narrow queries or in results for adjacent topics, and that's exactly where the most interesting donors are. Go through a dozen key queries of varying frequency and note which sites appear most often. Repeat appearances matter more than a single hit: if a resource consistently holds top positions across several of your topics, it definitely deserves a spot on your analysis list. Random one-pagers and aggregators without their own content can be filtered out right away so you don't waste time on them when analyzing links.

Step 2: break down their link profile

Once the list is ready, pull your competitors' link profiles in any of the tools: Ahrefs, Semrush, or Moz. You're not interested in every single link, but in referring domains, editorial links, and anchors. Domains that link to several of your competitors at once almost certainly accept guest content and should go into your priority list.

The connection between domains and rankings is not random. According to Backlinko, in a 2025 study, a page in the first position on Google has on average 3.8 times more backlinks than pages in positions two through ten. So when you break down a leader's profile, you're essentially looking at a map of what needs to be replicated and surpassed.

Also pay attention to your competitors' fresh links from recent months. They show where a rival is active right now and point to platforms that currently accept guest posts, not ones that closed down a couple of years ago.

Step 3: find the link gap

The link gap is a list of domains that link to your competitors but don't link to you yet. Almost all SEO tools can build this report automatically: you upload your site and two or three competitors, and the output gives you ready-made outreach targets. The more competitors got a link from a given domain, the higher its value.

But the gap isn't the whole strategy. According to Editorial.Link, in a 2026 survey 66.6% of specialists said that finding unique link opportunities brings more benefit than simply copying a competitor's profile. The practical takeaway: the gap gives you a starting list, but the real advantage comes when you find platforms your rivals haven't reached yet.

Step 4: evaluate and prioritize platforms

Not all donors are equally useful, so every platform on the list should be evaluated against several criteria. It's convenient to put them in a simple table and assign scores so decisions are made based on data, not intuition.

Start with platforms at the top of the list: high relevance plus openness to guest content gives the fastest result. Strong but closed sites can wait until you have a portfolio of publications and arguments for your pitch.

What not to do

Blindly copying someone else's donor list is the most common trap. If you simply repeat a competitor's path, at best you catch up to them, but you never overtake them. Besides, links cost money and time. According to Editorial.Link, in a 2026 survey the average acceptable cost of one quality link was $508.95, so spending resources on repeating someone else's strategy without your own angle is especially frustrating.

It's equally dangerous to fixate on the biggest platforms. A small niche site with a live audience often brings more targeted traffic and a more natural link than a giant where your content will get lost. A balance between authority and relevance almost always beats chasing size alone.

How to turn analysis into a publication plan

Data without action is useless, so the final step is translating analysis into a concrete plan. Take your prioritized list of platforms and spread it over the coming months: strong and open donors go first, harder targets get scheduled further out. That way analysis stops being a one-off report and becomes an outreach roadmap.

For each platform, immediately define your angle: what topic you'll pitch and how it complements what's already published. This step saves weeks, because by the time you write to the editor you already have an idea ready, not just a site address. It helps to keep everything in one spreadsheet: domain, contact, topic, correspondence status, and date of the next step.

Separately mark platforms that none of your competitors have. Those are the ones that give you a chance to break ahead, not just catch up. If you find a relevant site with a live audience where competitors haven't published yet, put it at the top of the list: the first link from such a donor is almost always worth more than the tenth link from a platform where everyone has already shown up.

Finally, set a date for your next audit. The market changes, competitors get new links, platforms open and close. A regular quarterly review of the list keeps your strategy current and prevents rivals from quietly pulling ahead.

Common mistakes in competitor analysis

• Confusing business competitors with search result competitors.
• Analyzing all links in a row instead of focusing on referring domains and editorial links.
• Blindly copying someone else's profile without looking for your own unique platforms.
• Ignoring relevance in pursuit of large but off-topic sites.
• One-off analysis instead of a regular quarterly audit.

⁉️🤔 Common questions about competitor analysis in guest posting

How do I find sites where competitors publish guest posts?

Open a competitor's link profile in Ahrefs or Semrush, filter links by "editorial" type, and examine the anchors. Sites with repeated links to several competitors most likely accept guest content: check for "Write for us" or "Guest post" pages.

What tools do I need to analyze a competitor's link profile?

For basic analysis, Ahrefs, Semrush, or Moz work well: they show donors, anchors, and link growth dynamics. Free alternatives, Ubersuggest and Google Search Console, give a partial picture. Combine two or three tools to reduce data margin of error.

What is link gap analysis and why is it needed?

The link gap is a list of platforms that link to competitors but not to you. The analysis shows specific sites for priority outreach: the more competitors got a link from a given domain, the higher that donor's value for your strategy.

Should I just copy competitors' links?

Copying a donor list is useful as a starting point, but blind repetition gives no advantage. Look for platforms where competitors aren't present yet, pitch deeper content, and cover adjacent topics to attract audiences your competitors ignore.

How often should I run competitor analysis in guest posting?

A scheduled quarterly audit lets you track new platforms and changes in rivals' strategies. If a competitor's traffic spikes or they launch in a new niche, run an unscheduled analysis right away: lost time here directly affects your search rankings.
