He was the club's top goalscorer in that competition with 12 goals. He was also the top goalscorer of the Campeonato Paranaense in 2008 with 18 goals. He played his first Série A match on 11 May 2008, when his club beat Palmeiras 2–0, although he suffered an injury in the match. He scored his first goal for the club on 9 July 2008 in a 4–0 win over Portuguesa. His first goal came less than a month later in a 0–0 win over Santos on 3 August 2008.

Keirrison joined Palmeiras in January 2009. He made his club debut on 24 January 2009 against Mogi Mirim, scoring twice in the 3–0 win. then twice in the preliminary round of the Copa Libertadores as Palmeiras beat Real Potosí 1–1 on 29 January 2010. On 26 June, it said on Palmeiras' official website that Barcelona had made an offer for the striker.
On 23 July 2009, Barcelona announced on its website it had had agreed to terms with Palmeiras to bring Keirrison to the Camp Nou. The transfer was worth €14 million plus a bonus up to €2 million contingent on the number of matches Keirrison played with the first team. Keirrison signed on a five-year contract. On arrival at the Spanish club, Keirrison expressed his adulation he had for his new club and was quoted as saying in Barcelona's official website, "I hope to break into [Barcelona head coach] Pep Guardiola's side, and join many other famous Brazilians who have played here." He added, "I always followed Barcelona and the Brazilian players who played here. Now at 20 years old, I am very happy to be here, fulfilling my dream of playing at the best club in the world." However, soon after, Guardiola stated "in principle he'll go out on loan". Many teams throughout Europe were linked with Keirrison after hearing of Barcelona's plan to loan-out the Brazilian in order to acclimatize him to European football, including Roma, Monaco and Ajax.
Loan to Benfica
On 28 July 2009, it was announced Portuguese Primeira Liga club Benfica agreed on terms to take the Brazilian on loan for the 2009–10 season. Keirrison scored his first goal for Benfica in a friendly against Celtic. However, with the abundance of strikers in form at Benfica, Keirrison found it hard to break into the first team; to some, Keirrison was behind Óscar Cardozo, Nuno Gomes and Javier Saviola in the pecking order at the Estádio da Luz. While in Portugal, Keirrison started one match for Benfica and played a total of just 199 minutes. In January 2010, then Benfica manager Jorge Jesus even went as far as to say that he did not plan to play Keirrison for the remainder of the season. Nonetheless, Keirisson became a Portuguese champion thanks to the five league matches he featured in for Primeira Liga winners Benfica.
Loan to Fiorentina
On 31 January 2010, Fiorentina announced on its website it had come to terms with Barcelona to take Keirrison on loan until the end of the 2011–12 season. Barcelona also granted La Viola an option to purchase Keirrison outright, after his loan, for €14 million. On 7 February 2010, just one week after being signed, Keirrison made his official debut for La Viola after coming on as a substitute for Manuel Pasqual in the 84th minute in a 1–0 loss against Roma. On 21 February, Keirrison came on as a substitute for Marco Marchionni in the 76th minute in a match against Livorno; Fiorentina went on to win that match 2–1. On 28 February, he replaced Adem Ljajić in the 46th minute against Lazio and he later went on to score the equalizer in the 92nd minute, his first goal for Fiorentina.
Return to Brazil
In March 2012, Keirrison was loaned to his original club, Coritiba, until the end of the 2013–14 season.
Permanent move to Coritiba
In September 2015, Keirrison went to court against Coritiba requesting unpaid wages and medical expenses from a surgery to recover from an injury. In November, after the club claimed to have paid the debt, Keirrison said he would not play in the next match against Figueirense, claiming he "would not be ready". One director told the reason might be that "he [Keirrison] checked his bank account and the money was not there yet", thus deciding not to play. He was released after the 2015 Campeonato Brasileiro Série A. Days l
