Yaoi is a Japanese based term and as such its meaning as well as the meanings of other related words are often misconstrued as people try to 'simplify' the terms to make them easier to understand. The most common misinterpretations include what is and what isn't considered Yaoi and the different meanings of Shōnen-ai throughout history.

Yaoi[]
Yaoi is a term for media created in Japan that focuses on the homoerotic relationships between male characters and has heavy sexual content. It is commonly used as a female-oriented term with regard to the genre's demographics, but the genre attracts a range of audiences.
As for the word itself, it stands for Yamanashi, Ochinashi, Iminashi, meaning No climax, no point, no meaning. Though some fans understand it as Yamette! Atashi no Oshiri Itai!, translated: Stop it! My butt hurts! Yaoi was basically a 'parody' of Shõnen-ai that was produced in the 70's and 80's in which people would write sexually explicit fan fictions of manga that were aimed for (pre-)pubescent girls. Since this form of shõnen-ai mimicked actual shõnen-ai (the action/adventure and comedy manga marketed towards young boys) it featured mostly male leads/characters.
In the end the parody was meant to poke fun of the fact that this 'new' shõnen-ai was hard to understand for its age group and so yaoi focused on the other half of this, also known as all the good guy on guy action.
Shōnen-ai[]
Before the term Yaoi was coined there was Shõnen-ai. The first misconception in the term lies in its target audience. Shõnen is marketed for boys between 10-17, with Shõjo being its female equivalent. Yaoi is primarily marketed towards a female audience.
Being targeted towards young males, the genre focuses on the platonic relationships between young male leads. It is meant for the time in a boy's life where he reads a lot of action and adventure oriented stories and as such female characters are normally found on the sidelines instead of in the main cast.
What actually defines Shõnen nowadays is the media outlet and time slots it is put out on in Japan, but Shõnen itself was essentially comics for young men.
Shōnen-ai (for works created in the 70's & 80's)[]
In the 70's & 80's the term 'Shõnen-ai' was used to describe a type of Shõjo (anime/manga targeting a young female audience) involving romance between young boys.
The reason shõnen-ai in the 70's & 80's differs from the general use of shõnen-ai is because the term is usually used to describe boy romances rather than the other subject matter within them. Shõnen-ai in the 70's and 80's, while marketed towards a younger audience, was hard to understand for younger readers who did not have a good grasp on classical literature and found it challenging able to grasp their deep philosophical themes.
The term Shõnen-ai stopped referring to the genre of Shõjo after the 80's but is still used by Westerners as a differentiation between explicit and non-explicit forms of male x male romances.
Tanbi[]
Tanbi is no longer written. Tanbi is a word meaning 'the worship and pursuit of beauty'. It was used to describe the early male/male stories that mainly ran in June. June was heavily influenced by a well-known author and literary critic who used multiple pen names, so many of the stories utilized a high literary style. These stories came to be called tanbi - stories written for beauty and pursuit of beauty only. Tanbi style includes flowery language and uncommon kanji/words, which makes it a difficult read for foreigners.
The tanbi style is mainly a thing of the past. It has been replaced by BL stories - mass written, easy-to-read stories. Even authors known for their tanbi works like Yoshihara Rieko (Ai no Kusabi) now write mainstream BL and no longer use tanbi style. It's probably because tanbi, like its name, pursues beauty both in language and storyline. It is not simple and fast-paced like the modern BL stories.
Tanbi is like Shõnen-ai, no longer written but important in the evolution of modern BL. It is sometimes used interchangeably with boys' love by bookstores, but that is an old usage.
Bara[]
Bara is yaoi often by men for men. It features more mature and realistic homoerotic relationships and adult like themes, targeted towards audiences in their 30's or so. The men in these are invariably muscular and masculine and appeal to male readers who dislike the feminine Bishonen portrayed in BL manga.
June[]
June was the term for original works beginning in the 1970s because the magazine 'June' was the first one known for running gay themed manga. June turned into boys love (BL) over time but sometimes it is still used.
Boys' Love[]
Boys' love (BL) is the common term used by the publishing industry to categorize works focusing on male/male relationships marketed at women. Historically these works were referred to as June, but most commercial works are now called BL. Fans in Japan use the term BL meaning Boys' Love, whereas international fans prefer to use Yaoi.
Seinen[]
Japanese manga that are classed as seinen would generally be targeted towards young adult males. Where shounen manga would be aimed at young teenage boys, the demographic for seinen works would be in the 18-40 age range. Josei manga is the female equivalent to seinen. Realism and seriousness is a trait of seinen works with an emphasis on the story and character experiences.
