The standard approach to competitor research on X is to read their tweets, study their content, and guess at their strategy. That approach shows you what a competitor chose to say publicly. It does not show you what they chose to pay attention to privately.
A following list is a private signal made public. Every account a competitor follows is an account they decided was worth watching, an information source, a community, an influencer, a space they are positioning themselves in. The overlap between your following list and a competitor's tells you where your strategic attention aligns and where it diverges. That is more useful than almost anything they post.
Circleboom's Account Comparison & Benchmark Report retrieves both following lists through official X access, computes the exact accounts you share in common, and returns them as a scored, filterable, actionable dataset, with full profile data for every shared account.

Why following overlap is the signal most competitor research misses
X shows you a competitor's following list if you visit their profile. What it does not show you is how that list relates to your own. The overlap between two following lists is invisible unless you compute it explicitly, and native X has no tool to do that.
That invisibility is expensive. The accounts both you and a competitor follow are the sources you share: the influencers you both monitor, the communities you both participate in, the conversations you both track. Knowing that shared set tells you something about common strategic ground. More importantly, it isolates the gap. The accounts they follow that you do not are their exclusive signals. The accounts you follow that they do not are yours.
Native X gives you a scrollable, unsorted, unenriched list of a competitor's following. You cannot filter it by quality. You cannot compare it against your own. You can scroll through it and guess, or you can compute the intersection directly and see what is actually shared.
What the overlap reveals
Shared following is a different signal than shared followers. Followers indicate audience. Following indicates attention. When two accounts in the same niche both follow the same analyst, the same community account, or the same emerging voice, that convergence is meaningful, both accounts independently decided that source was worth tracking.
The overlap composition tells you three things at once. Accounts that appear in the intersection are common ground: the influencers and sources both strategies converge on. The accounts in your competitor's following list that you do not follow are their exclusive signals, sources or communities they are tracking that you have not found yet. The accounts in your following list that are not in theirs are your edge.
All three views require the same computation. The gap between your list and theirs is only visible once the overlap is known.
How to compare your Twitter following list with a competitor's
Circleboom retrieves both following lists through the official X Enterprise API, computes the intersection, and returns the result with full profile data for every shared account.

Because Circleboom is an official X Enterprise Developer, the entire comparison runs through sanctioned API access, no scraping, compliant throughout.
1. Log in and connect your account Log in to Circleboom Twitter and authorize your X account through OAuth. This loads your account through the Enterprise API and enables the comparison tools.

2. Open Account Comparison & Benchmark Report Navigate to the Twitter Search Tool section and open Account Comparison & Benchmark Report. The input page shows two @ username fields with a connection icon between them and a Comparison History panel on the right that stores previous runs for quick re-access.

3. Enter both accounts and select Following Type your username in the first field and your competitor's in the second. Select the Following radio button, this compares the accounts both of you follow in common, not your follower bases. Click Compare X Accounts.
4. Review the intersection The results page shows the exact number of common accounts found and how many accounts were fetched from each side. Results appear in a sortable table with tweet count, account age, follower count, following count, follow ratio, and engagement tier for each shared account. Up to 5,000 common accounts are displayed, sorting by different columns surfaces different subsets beyond the default view.
5. Filter and act on the results Sort by follow ratio to surface the highest-credibility shared accounts first. Use the Find in Bio & Name filter to narrow by topic or keyword. From the results, follow accounts directly, add them to a Twitter List, whitelist them, or export the full intersection as CSV. The comparison result is cached after the first run, use the refresh function when you need an updated intersection based on current data from both accounts.
That sequence turns a scrollable, unsorted native list into a structured, actionable dataset. The intersection is visible in one view instead of being something you piece together manually.
What the comparison changes about your following strategy
Once the intersection is visible, your following list stops being something you built passively and becomes something you can manage with a reference point. You can see which accounts represent genuine shared ground with a competitor, and which ones are unique to either side.
The strategic use is in the gap. Running the comparison and filtering the results to find accounts your competitor follows that you do not surfaces sources you may be missing. These are accounts a competing strategy decided were worth tracking before you did. Adding the highest-quality ones from that gap to your own following is one of the fastest ways to close an information asymmetry that would otherwise stay invisible.
The Comparison History panel stores every previous run with the date it was executed. Running the same comparison across different periods shows how the overlap changes over time, whether your strategic attention is converging with or diverging from a competitor's as both accounts evolve.
The private signal that public tweets never show
A tweet is a statement chosen for public consumption. A follow is a decision made privately, and the accumulation of those decisions is where real strategic intent lives. Comparing following lists reads that private layer, not what a competitor wants you to see, but what they actually pay attention to.
A competitor who follows a cluster of accounts in a specific technical niche is signaling research direction. A competitor who follows the same analysts you do is competing for the same information edge. None of this is visible in their content. The comparison gives you access to that layer without them knowing you are looking, and what it reveals is often more predictive of where a competing account is headed than anything they have posted.

The mistake to avoid
The most common mistake after running a following comparison is treating the intersection as the only useful output. The shared accounts matter, but the non-overlapping portion is often more valuable, and the comparison result does not show that half automatically.
To see what a competitor follows that you do not, run the comparison and then examine their following list separately through the Followers / Following Search feature. The accounts that appear in their list but not in your intersection are the ones worth examining, the sources and communities they have identified that you have not, and the highest-quality ones from that gap are candidates for your own following list.
The second mistake is running the comparison once. A following list changes over time. A comparison from six months ago is a historical snapshot, not a current state. Running the same comparison quarterly turns a one-time audit into an ongoing signal.
Frequently Asked Questions
Does the competitor need to follow me for this to work?
No. Account Comparison retrieves publicly available following lists for any two public accounts. There is no requirement for a mutual follow or any existing relationship between the accounts. You can compare your account against any public competitor regardless of whether they follow you.
Can I compare two accounts that are not my own?
Yes. The comparison works for any two public accounts, you can enter two competitors against each other without your account being one of the inputs. This is useful for mapping how the following overlap between two third-party accounts relates to your own strategy, or for finding accounts that sit at the intersection of multiple influential following lists in your niche.
What if the overlap is very small?
A small overlap means your following strategy differs significantly from your competitor's, you are drawing from different sources and tracking different communities. That can indicate a genuine strategic divergence or simply that both lists grew in different directions over time. Either way, the gap is informative: it shows where their attention is going that yours is not.
How many results does the comparison return?
Results display up to 5,000 common accounts. For large accounts, the results page notes how many accounts were actually fetched from each side, the intersection is computed from the fetched portion. Sorting by different columns surfaces different subsets of the full intersection beyond the default view.
The Bottom Line
Your following list is a record of where your attention has gone. A competitor's following list is theirs. The overlap between them is common ground that native X will never show you, because it has no tool to compute it.
Run the comparison, review the intersection, look at the gap on both sides, and use what you find to compare your Twitter following list with a competitor's and close the information asymmetry that has been there all along.
