Plaintiff-Appellant TradeComet.com LLC (“TradeComet”) appeals from a judgment entered pursuant to an opinion and order of the United States District Court for the Southern District of New York (Sidney H. Stein, District Judge) dismissing its complaint. TradeComet brought this action against Defendanh-Appellee Google, Inc. (“Google”) for alleged violations of the Sherman Act, 15 U.S.C. §§ 1, 2, arising out of TradeComet’s use of Google’s “AdWords” search engine advertising platform (“AdWords”). Google filed a motion to dismiss pursuant to Rules 12(b)(1) and 12(b)(3) of the Federal Rules of Civil Procedure for lack of subject matter jurisdiction and improper venue. Google argued that TradeComet had accepted the terms and conditions associated with participation in its AdWords program, which included a forum selection clause requiring TradeComet to file its suit in state or federal court in Santa Clara County, California, not in New York. TradeComet contended,
inter alia,
that a district court may only enforce a forum selection clause permitting an alternative federal venue pursuant to 28 U.S.C. § 1404, which authorizes transfer of the case to the agreed-upon venue, rather than through Rule 12(b). In an opinion and order dated March 5, 2010, the district court rejected this argument and concluded that Google could seek enforcement of its forum selection clause by moving to dismiss pursuant to Rule 12(b). The court then applied our four-part test for determining whether to dismiss a claim based on a forum selection clause,
see Phillips v. Audio Active Ltd.,
Here, TradeComet renews its argument that a § 1404(a) motion to transfer is the only appropriate vehicle for enforcing a forum selection clause when the clause at issue permits an alternative federal forum. We reject TradeComet’s argument and hold, consistent with our precedents, that a defendant may seek enforcement of a forum selection clause through a Rule 12(b) motion to dismiss, even when the clause provides for suit in an alternative federal forum. In a contemporaneous summary order filed with this opinion, we conclude that the district court properly applied our test in Phillips to dismiss TradeComet’s complaint.
BACKGROUND
Because we are reviewing the district court’s dismissal of a complaint pursuant to Rule 12(b) of the Federal Rules of Civil Procedure, we view the facts in the light most favorable to TradeComet.
See Phillips,
Google requires AdWords users to accept certain terms and conditions to activate an AdWords account. Google also requires AdWords users to agree to any subsequent modifications or additions to these terms and conditions in order to continue advertising with AdWords. Over the course of TradeComet’s participation in the AdWords program, Google issued three agreements delineating its terms and conditions. Two of them contained a forum selection clause providing that “[t]he Agreement must be ... adjudicated in Santa Clara County, California.” The third, effective August 2006, provided that all claims “arising out of or relating to this Agreement or the Google Program(s) shall be litigated exclusively in the federal or state courts of Santa Clara County, California.”
Subsequent to the filing of TradeComet’s complaint, Google filed a motion to dismiss for lack of subject matter jurisdiction and improper venue, pursuant to Rules 12(b)(1) and 12(b)(3) of the Federal Rules of Civil Procedure. Google argued that the forum selection clause contained in its August 2006 terms and conditions applied to TradeComet’s antitrust claims, and that the clause required TradeComet to file its suit in a state or federal court located in Santa Clara County, California. In opposing the motion, TradeComet contended, inter alia, that the district court was required to convert Google’s motion to dismiss into a motion to transfer pursuant to 28 U.S.C. § 1404(a), since the forum selection clause permitted venue in a different federal forum. The district court concluded that a motion to dismiss pursuant to Rules 12(b)(1) and 12(b)(3) was a proper vehicle for enforcing a forum selection clause, and found that the August 2006 forum selection clause applied to TradeComet’s antitrust claims. The district court granted Google’s motion to dismiss the complaint. This appeal followed.
DISCUSSION
TradeComet primarily argues on appeal that the district court erred in dismissing its case pursuant to Rule 12(b), rather than considering whether to transfer it to an appropriate federal court pursuant to § 1404(a).

TradeComet con
*475
tends that a district court must enforce a forum selection clause pursuant to § 1404(a), and convert a Rule 12(b) motion into a motion to transfer, when the clause at issue provides for suit in an alternative federal forum. TradeComet thus argues that a Rule 12(b) motion to dismiss is available solely when a forum selection clause specifies only foreign and/or state fora as acceptable venues for adjudicating the parties’ disputes. We review
de novo
a district court’s dismissal of a complaint pursuant to Rules 12(b)(1) and 12(b)(3), viewing all facts in the light most favorable to the non-moving party.
See Phillips,
I.
The enforcement of a forum selection clause through a Rule 12(b) motion to dismiss is a well-established practice, both in this Circuit and others.
See, e.g., Phillips,
In determining whether a Rule 12(b) motion to dismiss pursuant to a forum selection clause was properly granted, we have analyzed the enforceability of such clauses by applying the standards set forth by the Supreme Court in Bremen,
4
See, e.g., Phillips,
To the extent TradeComet attempts to distinguish
Bremen
as announcing a narrow rule to be applied solely in international cases, or those arising under admiralty law, we are not persuaded. Although
Bremen
was an admiralty case and in
*476
volved international trade, we have recognized that its reasoning extends beyond the admiralty and international contexts.
See Phillips,
Bremen,
therefore, did not create a narrow rule holding forum selection clauses to be
prima facie
valid solely in admiralty cases, or those involving international agreements, but rather approved of a preexisting favorable view of such clauses.
See Evolution Online,
TradeComet argues that a district court nevertheless errs in enforcing a forum selection clause pursuant to
Bremen
by granting a Rule 12(b) motion to dismiss when the clause provides for an alternative
federal
forum to which the matter could be
transferred
pursuant to § 1404(a). While admittedly most of our precedents have involved forum selection clauses specifying a
foreign
forum,
5
none of them reasoned that our application of
Bremen
and the propriety of granting a motion to dismiss turned on the absence of a federal forum in which suit could be brought.
Cf. Phillips,
II.
TradeComet argues that even if such dismissals may have been permissible pri- or to the Supreme Court’s decision in
Stewart Organization, Inc. v. Ricoh Corp.,
Stewart
did not consider the circumstances in which a defendant may seek dismissal pursuant to Rule 12(b) in order to enforce a forum selection clause. Instead, the Supreme Court addressed the question “whether a federal court sitting in diversity should apply state or federal law in adjudicating
a motion to transfer a case
to a venue provided in a contractual forum-selection clause.”
7
TradeComet’s reading of
Stewart
is further undermined by the Court’s subsequent decision in
Shute,
where it applied the
Bremen
rule in an admiralty case to uphold a forum selection clause permitting suit in a federal forum.
Shute,
The better reading of
Stewart,
one that gives effect to the Court’s three decisions, is that
Stewart
deals with motions to transfer pursuant to § 1404(a), while
Bremen
and
Shute
address the grant of dismissal or summary judgment based on a forum selection clause.
Cf. Jones,
For these reasons, we reaffirm our prior precedents and hold that a district court is not required to enforce a forum selection clause only by transferring a case pursuant to § 1404(a) when that clause specifies that suit may be brought in an alternative federal forum. Rather, in such circumstances, a defendant may seek to enforce a forum selection clause under Rule 12(b). The district court therefore *479 properly considered Google’s Rule 12(b) motion to dismiss the complaint.
CONCLUSION
We emphasize the limited nature of our decision. Our focus is solely on whether a district court called upon to enforce a forum selection clause is
required
to enforce it pursuant to § 1404(a) whenever the clause permits suit in an alternative federal forum. Consequently, we do not address the related, but separate, question whether a district court may,
sua sponte,
convert a Rule 12(b) motion to dismiss into a § 1404(a) motion to transfer.
9
We also do not address circumstances in which a defendant moves in the alternative for both dismissal under Rule 12(b) and transfer under §§ 1404 or 1406(a),

Notes
. In a prior decision, we described AdWords in the following manner:
AdWords is Google’s program through which advertisers purchase terms (or keywords). When entered as a search term, the keyword triggers the appearance of the advertiser’s ad and link. An advertiser’s purchase of a particular term causes the advertiser's ad and link to be displayed on the user's screen whenever a searcher launches a Google search based on the purchased search term. Advertisers pay Goo *474 gle based on the number of times Internet users "click” on the advertisement, so as to link to the advertiser’s website.
Rescuecom Corp. v. Google, Inc.,
. According to TradeComet’s complaint, such websites are commonly referred to as "business to business” (or "B2B”) search or exchange websites.
. Section 1404(a) provides: "For the convenience of parties and witnesses, in the interest of justice, a district court may transfer any civil action to any other district or division where it might have been brought.” 28 U.S.C. § 1404(a).
. Both parties agree, consistent with the choice of law provisions in Google’s terms and conditions for AdWords, that federal law governs the enforceability of the forum seleclion clause, while California state law controls the interpretation of that clause.
