MLA style requires you to cite websites similar to the way you cite print publications. If the website names an author, that goes first, with the last name followed by the first name. Next comes the title of the article or page in quotation marks, then the name of the website in italics. In the case of a journal or webzine, include issue numbers or similar identifying information next, then write the name of the publisher and the date of publication. End with the date you accessed the website, as online content sometimes moves or disappears.
As with the works cited page, cite websites in as similar a style to that of other citations as possible. Refer to the website name, rather than its Web address, or URL. Alternatively, in a parenthetical citation, refer to the first piece of information displayed in its work cited page listing. For example, cite the author's name if that is how the works cited page entry begins.
You do not need to provide website addresses, or URLs, either in the body of your essay or on the works cited page. MLA used to have this rule, but it changed in 2010. The title of the article or page and the name of the website provide enough information for the reader to search for it herself. The only exception is if your school specifically requires an URL. Check with your tutor if in doubt.
A website may include its domain suffix, such as .com or .org, as part of its official name. In these cases, include the suffix in the name when citing it. Including the suffix is also useful to distinguish online versions of a publication from its print counterpart, especially where the Web version differs. If the suffix is clearly unneeded for identifying the website, do not include it. "Google" stands alone, for example, so you would not write "Google.com." Sometimes, the website name bears no relation to the URL.
