The species within subfamily Chenopodioideae are difficult to distinguish between. They often include several varieties whose identification usually requires the use of a microscope. One of the important distinguishing characters is the texture of the seed-coat. The genus is easily confused with oraches (Atriplex spp.). However, the latter have unisexual flowers and characteristic fruit-enclosing bracts.

Many-seeded goosefoot, also known as all-seed, usually has a lax stem with an ascending top. It is often (at least when older) reddish and quadrangular in cross-section. Many-seeded goosefoot, like many of its relatives, is an annual favoured by traditional farming practices and other human activities. It is usually encountered in fertilised fields and on other nitrogen-rich sites. Also clayey and rocky shores are suitable habitats for this plant.

Many-seeded goosefoot can be distinguished from very common fat hen (C. album) by that it lacks hairs and has leaves with entire margins.
