The pair joined 44 other websites – including the likes of Google, BBC, Top Shop and Streetmap – singled out by the Superbrands council for their strength in the online world and reputation among users.
The announcement is the first time that a dedicated online project – eSuperbrands – has been carried out by the Superbrands organisation.
A range of online brands were selected for scrutiny by the council, which includes the likes of Brent Hoberman, chief executive of Lastminute.com and Travelocity Europe, and chief executive of FriendsReunited, Michael Murphy.
A final 46 brands were revealed at a ceremony in London this week.
Chairperson of the eSuperbrands Council, Donna Price, said: “The interesting thing is the success and strategy employed by the mix of traditional brands, that we have known and loved for years, with other younger pure e-brands that have been developed more recently.
“With the proliferation of websites both reputation and brand image are becoming ever more important in aiding consumer choice.
“Those brands featured in the eSuperbrands publication are a suitable benchmark of those that truly deliver.”
The finalists were also selected for a research project carried out by YouGov to determine consumer behaviour with online brands.
Google and BBC.co.uk came out in top for categories to find the most popular and trusted online brands.
Mytravel.co.uk and Teletextholidays.co.uk featured high in categories to determine where consumers would like to go if they had a spare hour or £100 to spend.
