I thought there was a pinned "topic" dealing with the suggested format for licensing suggestions, but I'm not seeing it; there are only two pinned topics in this area... It's always good to look at this topic to see if there is already a suggestion topic for a given work; it's not all inclusive, as they update it irregularly and if a new topic was created in the interim it won't show, so it's also good to search to see if one was created since then.
Something like what I put together increases the likelihood of others checking out an unfamiliar title.
I have to admit that I go a bit overboard, which has something to do with being a retired librarian; information wants to be shared!
Bookwalker links are useful in that Bookwalker generally has extensive previews available, to the extent that other retailers link to them; they're in Japanese, but you still get all the "beginning of volume" illustrations, and if you do read Japanese...it's a preview!
Linking to MAL or ANN if they have entries provides some level of information in English.
The Publisher link makes it possible to keep on top of what's come out in Japan.
The Twitter & Pixiv links help get a feel for the author and illustrator's other work and involvements.
In some cases there will be Wikipedia entries.
There are sites that J-Novel dislikes our linking to, such as Novel Updates; publishers of Licensed translations have good reason to not want links that lead to unlicensed translations [it can negatively impact their relation with the Japanese publishers if nothing else] or other materials with iffy IP status; this also includes any images linked, they need to come from sites where there is reason to believe the IP rights holders approved their being posted [so sometimes you don't go with the highest resolution image you can find due to where it comes from].
And, um, yes, I tend to be verbose.
