🚀 Competitor analysis for a guest blogger: a step-by-step breakdown

Why analyze competitors before a guest post

Competitors have already tested hundreds of headlines, platforms, and topics for you, and you can simply read the results. Their published guest articles show which platforms actually deliver traffic, which topics resonate with the audience, and where niche leaders still have gaps that you can fill.

Most authors write guest posts blindly: they grab the first platform they find and a topic "off the top of their head." The outcome is predictable, the article sinks. Competitor analysis turns guesswork into data. And the numbers back this up: according to Ahrefs, 60% of guest posts are published on sites with a Domain Rating of 60 or higher, because those are the platforms that actually produce results.

Below is a working 6-step algorithm, real tools, a metrics table, and specific numbers that will help you outpace competitors instead of copying them.

💡 **Quick overview: how to outpace competitors in **guest blogging

• Identify 5-10 direct competitors through organic search and backlink reports
• Find the platforms where they publish and filter by Domain Rating 60+
• Run a content gap analysis: topics they cover that you don't
• Strengthen the format: long posts of 1,500+ words get 68% more shares (Orbit Media)
• Close competitors' weak spots with unique experience and data
• Measure results by referral traffic, not by the number of links

Who your competitor actually is

Your competitor is not someone with a similar blog, but someone who ranks for your target queries. These two lists often don't match. A food blog author may compete for guest slots with a marketing agency if both are aiming for the same productivity platform.

Divide competitors into three levels. Direct: authors in your niche who publish on the same sites. Indirect: those who compete for the same audience's attention through different content. And "search" competitors: pages that Google shows above you for your target keywords. Interestingly, 47% of SEO specialists in 2025 consider their main competitors to be those selling a similar product, even though in search results they often compete with entirely different sites.

To build the real list, enter your domain in Ahrefs Site Explorer and open the "Organic competitors" report. It will show sites that overlap with you on keywords. Then you look not at their blog as a whole, but specifically at their guest posting activity.

How to find sites where your competitors publish

The fastest way to find sites is to take a competitor's backlink profile and filter for guest links. Open the Backlinks report in Ahrefs or Semrush, sort by link type, and find domains where the author appears as a guest contributor. Those domains are your ready-made list of sites to pitch.

Why does this work so well? Because guest links are the foundation of the internet's link mass. According to Ahrefs, in 2025, 56.4% of pages have at least one backlink obtained through a guest post. And Outreach Monks research shows that 65% of all backlinks come specifically from guest posts. Sites that accept your competitors will almost certainly accept you too, if your pitch is stronger.

Don't chase volume. Ten high-authority sites are better than a hundred weak ones. According to Ranktracker, a link from a DR 70+ domain has 5.2 times more ranking impact than a link from DR 30, and a backlink from a relevant site in the same niche is worth 2.7 times more than a link from an unrelated site. Site quality is what matters.

Content gap analysis: finding topics you don't have

Content gap analysis is the search for topics your competitors have successfully covered, but you haven't yet. The tool compares the keywords your competitors rank for with yours and produces a list of "holes" ready to be filled.

In Ahrefs Content Gap, you add your domain at the top and up to 10 competitors below, then click "Show keyword opportunities". Filter the results by search volume of 20 or more and keyword difficulty (KD) up to 30. This will reveal the low-hanging fruit that's easy to rank for. Each such topic is a potential guest post that already has demand.

Distinguish between two types of gaps. A domain gap occurs when a competitor has an entire topic that you don't have at all. A page-level gap occurs when you both have an article on a topic, but their page ranks for more keywords. The first type gives you ideas for new guest posts, the second suggests how to rewrite existing ones more effectively.

Metrics to evaluate a competitor by

Compare competitors across several metrics at once, not just one. Domain Rating alone is misleading: a site with high DR but zero page traffic will give you less value than a relevant page with real visitors. Below are the key indicators and why each one matters.

Why are referring domains more important than DR? Ahrefs studied 218,713 domains and found a clear correlation between the number of referring domains to a page and its organic traffic, and it's the strongest of the link-based ranking factors. DR is useful as a proxy for authority, but it's the live referring domains and real page traffic that tell you whether a slot is worth fighting for.

Ten links from relevant, authoritative sites will give you more than a hundred links from topically unrelated sites. Relevance works as a multiplier, not as a nice bonus.

How to outperform a competitor, not copy them

Analysis isn't for copying, it's for doing better. When you see that a competitor covered a topic superficially, your job is to cover it more deeply: add data, personal experience, fresh numbers, and a format they don't have.

Start with length and format. Orbit Media research shows that guest posts longer than 1,500 words get 68.1% more tweets and 22.6% more Facebook likes. Long, well-structured content both ranks better and spreads further. Add statistics to that: 88% of content marketers include images in their materials, 60% use data and figures, and 45% add expert quotes. If a competitor does not do this, you get an advantage automatically.

And remember E-E-A-T. Google explicitly warns that large-scale guest posts for links violate its guidelines, so focusing on quality and author experience is not an option, it is a necessity. At the same time, 86% of SEO specialists have already built AI into their strategies. That means templated text without personal experience drowns in the general noise. Your real knowledge of the niche is something AI cannot fake.

Mini case study: what closing the gap looks like in practice

In practice, when we analyzed guest profiles in the marketing niche, the same scenario repeated over and over. An author finds that three competitors publish on a site with DR 65, but all their guest posts are short notes under 800 words with no data. They pitch the same site a 1,800-word piece with a table and three recent studies. Based on the data above, that format predictably gets 68% more shares, and a site with DR 60+ falls exactly into the segment where companies get 97% more inbound links from a blog. Not a made-up "+32% conversion," but a predictable effect from the right format on the right site.

What tools to use for analysis

For a solid analysis, two or three tools are enough, not a dozen. The main thing is to cover three tasks: find competitors, study their links and platforms, and find content gaps. Here is how they map out.

• Ahrefs or Semrush: the flagships for backlink analysis, finding organic competitors, and content gaps. Paid, but they pay off in serious niches.
• Google Search Console: a free source of your own queries, so you can see where you are already close to the top and which gap to close first. This is Google's official tool.
• Web analytics: the basic discipline of measuring traffic and behavior. Its fundamentals are worth understanding before you interpret other people's numbers.

Be careful with interpretation. Correlation between links and traffic is not the same as causation: Ahrefs explicitly notes that their research shows a relationship but does not prove causality. Use metrics as a guide, not as a law.

How to measure your own results

Measure success by referral traffic and leads, not by the number of links you got. A link from an authoritative platform can bring referral traffic for years, but only if the content is relevant to its audience. So counting "how many links I placed" is a dead end.

Track three metrics. Referral traffic from the platform will show whether real readers came. Rankings for target keywords will show whether you are growing in search results after publishing. And engagement: guest posts from opinion leaders boost social media activity by up to 60%. These three numbers are more honest than a link counter.

Keep a steady pace. Experts recommend 2-3 guest posts per month, and that is enough to grow authority without burnout. The quality of one strong publication beats five weak ones.

⁉️🤔 Popular questions and answers

How many competitors should you analyze before a guest post?

Take 5-10 direct competitors, that is enough for a reliable picture. Ahrefs Content Gap lets you compare up to 10 domains at once. Fewer than five gives an unrepresentative sample, and more than ten leads to duplicated data and a drawn-out analysis with no extra benefit.

What Domain Rating is considered good for a platform?

Aim for DR 60 and above: according to Ahrefs, 60% of guest posts are published on sites like that. A link from a DR 70+ domain has 5.2 times more impact than one from DR 30. But also check the page's actual traffic, because a high DR with no visitors is useless.

Does guest blogging still work in 2025?

Yes, and it remains the leading link building strategy. According to Outreach Monks and Ahrefs, 65% of all backlinks come from guest posts, and 56.4% of pages have at least one such link. What changed is the key: instead of mass publishing on weak sites, targeted placement on authoritative and relevant platforms now works.

How long should a guest post be?

Aim for 1500+ words. Posts of that length get 68.1% more tweets and 22.6% more Facebook likes, according to Orbit Media. Long-form content covers the topic more deeply, ranks better, and gives more reasons to be cited. But do not pad it just to hit a word count, because every paragraph should deliver value.

How is content gap analysis different from regular competitor analysis?

Competitor analysis answers the question "who are my rivals and where are they strong." Content gap goes further: it finds specific topics and keywords where competitors rank and you do not. That turns observation into an action list, meaning ready-made guest post ideas with already proven demand.

Can you get by with free tools?

Partially. Google Search Console will show your own queries and positions close to the top for free. But for deep analysis of other people's links and platforms, you need Ahrefs or Semrush, because free alternatives give too incomplete a picture of a competitor's backlink profile to build a strategy on it.

💎 Summary and conclusions

Competitor analysis is not a one-time action, it is a system. To start, do this: collect 5-10 direct competitors through the organic report, pull their guest platforms from the backlink profile, filter by DR 60+, and run a content gap to find topics with demand. Then hit their weak spots with long-form content of 1500+ words, with data and personal experience, where competitors are lazy.

The main pitfall: do not chase the number of links. Ten placements on relevant authoritative platforms will beat a hundred random ones, because a relevant link from your niche is worth 2.7 times more than an unrelated one. And remember correlation versus causation: metrics give you a guide, but what decides is the quality of your content and the real value for the platform's audience.
