Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill As of July 31, 2017 and January 31, 2017, the Company had goodwill of $4.7 million and $4.4 million, respectively. Goodwill represents the excess of cost over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company has no other intangible assets with indefinite lives. Goodwill is not amortized but is subject to periodic testing for impairment in accordance with GAAP at the reporting unit level, which is at or one level below the Company’s operating segments. The test for impairment is conducted annually each November 1^st, or more frequently if events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company determined that no events occurred or circumstances changed during the six months ended July 31, 2017 and 2016 that would more likely than not reduce the fair value of the Company's reporting unit below its carrying amount. However, if market conditions deteriorate, it may be necessary to record impairment charges in the future. Intangible Assets As of July 31, 2017 and January 31, 2017, the Company had intangible assets, net of $2.9 million and $3.1 million, respectively. The Company's intangible assets include customer relationships, website development, trade names and trademarks, acquired technology and domains. These intangible assets are amortized using the straight-line method over their estimated economic lives, which range from 3 to 15 years. Intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The Company determined that no events occurred or circumstances changed during the six months ended July 31, 2017 and 2016 that would indicate that its intangible assets with finite lives may not be recoverable. However, if market conditions deteriorate, it may be necessary to record impairment charges in the future. Amortization expense related to intangible assets totaled $0.1 million and $0.3 million for the three and six months ended July 31, 2017, respectively, and $0.2 million and $0.4 million for the three and six months ended July 31, 2016, respectively.
