Does the filename of an image matter for SEO?

Question

Search Engine Optimization

Which file is better " telefon-samsung-s2 .jpg" or " 785358438534 .jpg"? And does it affect at all?
Articles on SEO say that the first is better, but in practice ... I looked at many large online stores - there are practically no transliterated names for images.

Answer 1

The most important is the alt title! From this data, the search engine determines that the image and its relevance to the post or topic

Answer 2

I think that the alt attribute is more important, and what name does not matter.

Answer 3

Representatives of Yandex, for example, said that hundreds of parameters influence ranking (maybe thousands, I don’t remember exactly) and it is not known what ranking algorithms (based on what indicators and parameters) Matrixnet invented for itself. If it’s not difficult to make a name with a key or just a drawing that describes the theme, then it definitely won’t be worse, but it’s quite possible that it’s better

Answer 4

Yes, it does, but much less than alt.

Answer 5

the first option is better, but the impact on search results is minimal. In the search for pictures, a little more, but also not noticeable in practice.
It's like "eat more pepper it has a lot of vitamin C, more than a lemon", just try to eat black ground pepper by weight as much as a lemon weighs, this is his whole glass. So not everything that is "good for SEO" is "good for SEO" as strange as it may sound.

Answer 6

ceteris paribus,
this is when the search engine could not determine what is in the picture

Answer 7

Only alt, the rest has minimal values, and if they cannot be filled with a script, it is better not to waste time, but to spend it on more important things.
