How to Do a SERP Analysis That Tells You Which Keywords You Can Actually Win

SEO Vein Finder's What we checked panel: the search filters, the funnel counts narrowing 417 candidate keywords down to 26 that passed both thresholds, and per-keyword verdicts showing each keyword's minimum referring-domain count against the 300 maximum, with keywords over the limit marked Too competitive.

A SERP analysis answers one question: if I write a page targeting this keyword, can it realistically rank? The honest way to answer it is to look at the pages that already rank and measure how strong they are. This guide walks through that workflow the way SEO Vein Finder does it — with real top-10 results and referring-domain counts, not a black-box difficulty number.

What you are actually looking for

Search engines lean heavily on links when deciding which pages deserve the top positions, so the number of unique websites linking to a ranking page's domain — its referring-domain count — is a strong, inspectable proxy for how hard that page is to displace. The key insight: you do not need to beat the strongest result on the page. You need to beat the weakest one, because that is the slot a new article can take.

A keyword where every ranking page sits on a domain with hundreds of thousands of linking sites is a wall. A keyword where even one top-10 page sits on a small site with a few hundred linking domains is a door. SERP analysis is the process of telling those two apart before you write a word.

The workflow, step by step

Step 1.Search a seed keyword with your own thresholds

Start from a seed keyword in the Keyword Search view. Before running, set the filters that define "worth it" for your site: a minimum monthly search volume, a maximum referring-domain count for the weakest top-10 page, and the search intents you care about (for example Compare and Ready to buy if you write buyer-focused content). These thresholds are yours — the tool scores everything against them, not against a generic average.

Step 2.Read the results table

Each keyword that survives your filters gets a row with its monthly volume, the referring-domain count of its weakest ranking page (on Google and on Bing), and three scores: Volume, Ease, and the combined Opportunity score with its tier. Sort by Opportunity to bring the best winnability-versus-demand trade-offs to the top. A High tier means the competition is weak relative to your threshold and the demand is real.

Step 3.Inspect the weak spots in What We Checked

This is the actual SERP analysis. Expand the What We Checked panel and open any keyword to see the top 8 organic results with a domain-level referring-domain count for each one. You are looking for the pattern that signals an opening: a small, thin site holding a top position while the results around it are heavyweight brands. When the #1 result is a niche site with a few hundred referring domains and everything below it is a giant, that keyword is winnable — and you can see exactly why, result by result.

Step 4.Check the funnel, not just the winners

The same panel shows how the candidate pool narrowed: how many keywords came back from discovery, how many passed your intent and volume filters, how many were checked against the live results, and how many passed both thresholds. Keywords that failed are listed with the reason — for example a weakest-page count above your maximum — so a rejected keyword is a measured decision, not a mystery.

Step 5.Run a Domain Gap check on a competitor

When you want to know which keywords a specific competitor wins that you do not, switch to the Domain Gap tab. Enter your domain and theirs; the tool finds keywords they rank for that you do not, then runs those keywords through the same volume, referring-domain, and scoring pipeline. You get a ready-made list of proven topics, already filtered for weak competition.

What a good result looks like

A keyword worth writing about has three properties: volume above your minimum, at least one clearly weak page in the top results, and an intent that matches the content you plan to publish. When all three line up, the Opportunity score reflects it — 60% Ease from the referring-domain weakness, 40% Volume from the demand — and the keyword lands in the High tier. From there you can add it to your content plan, generate the article, and publish it to WordPress or Blogger without leaving the tool.

Frequently asked questions

What is a SERP analysis?

A SERP analysis means looking at the search results page for a keyword and judging whether a new page from your site could realistically rank there. Instead of trusting a single difficulty number, you inspect the pages that actually rank: who they are, how strong their link profiles are, and whether any of them look beatable.

Why use referring domains instead of a keyword difficulty score?

A keyword difficulty score is a proprietary blend computed differently by every tool, and you cannot see what went into it. A referring-domain count is a concrete number tied to the specific pages ranking for that keyword. If the weakest page in the top results sits on a domain with few linking sites, that is an opening you can verify yourself.

How many results does SEO Vein Finder check per keyword?

For each keyword that passes your volume and intent filters, SEO Vein Finder pulls the live top results on Google and Bing and shows the top 8 organic results in the What We Checked panel, with a domain-level referring-domain count for each one.

Can I try this workflow without an account?

Yes. The demo's Keyword Search view runs the same workflow on static sample data — results table, scores, and the What We Checked panel — with no signup. Running live searches on your own keywords requires an account.
