He spent most of his professional career with Real Sociedad after signing with the club at the age of 21, going on to appear in 227 official games during 11 seasons. 124 of those appearances came in La Liga (six goals scored).
Ansotegi was born in Berriatua, Basque Country. After starting his professional career with SD Eibar (with a loan to Barakaldo CF included), he moved to local giants Real Sociedad. He made his La Liga debut on 22 January 2006 in a 3–3 home draw against Athletic Bilbao for the Basque derby, and played 33 games in his first two top flight seasons combined.
Ansotegi only missed two matches in 2009–10, being booked just six times in his 40 complete appearances – and adding four goals – as Real Sociedad returned to division one after a three-year absence. He featured in 32 contests (all starts) in the following campaign as the team retained their league status, but lost his importance in the squad following the January 2011 signing of Norwegian Vadim Demidov and the emergence of youth product Iñigo Martínez.
On 1 June 2015, aged nearly 33, Ansotegi renewed his contract with Real Sociedad until 2016. On 1 February of the following year, after only two Copa del Rey appearances during the first part of the season, he cut ties with the Txuriurdin and moved back to his first club Eibar after agreeing to an initial six-month deal.
