In singles, she won one title at the LTA Junior International Tournament – Bisham Abbey where she beat compatriot Elena Baltacha in the final.

Keothavong played her first professional match on the ITF Women's Circuit in April 1998, at age 14, when she fell in the first round of qualifying for a $10k tournament in Birmingham.

[16] During May 1999, Keothavong played in a total of five ITF tournaments with her best result being in the $10k event in Sunderland where she won three matches to qualify and then reached the second round.

In March, she reached the quarterfinals of Redding, California ($25k) and in April she headed to Portugal to represent Great Britain in the Fed Cup.

Keothavong did not compete again until mid-June when she was given a wildcard into the main draw of the Eastbourne International where she was defeated by Japanese veteran, Ai Sugiyama.

A second consecutive wildcard gave her entry into the main draw of the Wimbledon Championships where she had to withdraw during her first-round match against Katarina Srebotnik with the score at 2–6, 0–4.

Reaching the final round of qualifying for the US Open, she lost to Maureen Drake and had no more notable results that year which she finished with a singles ranking of 177.

In February, she reached the quarterfinals of ITF events in Sunderland ($25k) and Saint Paul ($50k), beaten by Lisa Stanciute and Jill Craybas, respectively.

In late April and early May, she represented Britain in the Fed Cup and won all three of her singles rubbers, but lost her one and only doubles match with partner, Elena Baltacha, before going on to lose in the first round of qualifying for the French Open to Květa Peschke.

[16] Keothavong recovered well from her injury and returned to action ahead of schedule in March at the $10k tournament in Sunderland where she suffered a three-set first-round defeat by Verdiana Verardi.

After this, another wildcard allowed Keothavong entry into the main draw of Wimbledon where she faced Mariana Díaz Oliva in the first round and lost in straight sets.

Keothavong competed on the ITF Circuit for the rest of the year (except when she reached the second round of the Tier-III event, the Bell Challenge, where she lost to Sofia Arvidsson) and won two more titles.

The first was in Nottingham where she beat Karen Paterson in a three-set final, and the second was a $25k tournament in Lagos where she defeated Maša Zec Peškirič to win the title.

She then entered the $25k event in Sunderland where she beat four compatriots; Melanie South, Rebecca Llewellyn, Sarah Coles and Katie O'Brien in straight sets to reach the final where she was beaten by Elise Tamaëla.

Continuing competition on the ITF Circuit, she won a $50k tournament in Jounieh, Lebanon (despite break outs of fighting between Shia and Hezbollah militia less than ten miles away in Beirut).

[30] After Wimbledon, Keothavong made a successful start to her American hardcourt season by winning three matches to qualify for the Tier II event in Stanford.

Keothavong also played in the doubles with Ayumi Morita against Julie Coin and Marie-Ève Pelletier, trailing 4–6, 5–3 when she attempted to run down a drop shot and, in trying to avoid a collision with the net post, suffered a serious knee injury, rupturing her left anterior cruciate ligament and meniscus, a similar injury to the one she suffered in 2004 in her right knee.

Keothavong went straight into the main draw at the Australian Open, but had to retire due to illness from her first-round match, after losing the first set to Mona Barthel.

Despite this, she was still named in the Fed Cup team alongside Laura Robson, Heather Watson and Johanna Konta to face Portugal, Hungary and Bosnia.

[61] Keothavong's greatest strength is her powerful forehand which she uses to try to dominate play from the baseline and she adds as much topspin as possible to increase the probability of the ball landing in court.
