Exporting as SVG only exports vector elements?

[AspiringPerson]

I have a logo placed on a website I'm building. The photo however shows up as blurry when resized. After some digging, I found that it's better to use SVG files for logos instead of PNGs as it contains vector information. I go back into designer and save the logo as a SVG file. 

The issue is that the SVG file once saved only contains the vector information and not raster information in the logo. I used raster for painting shadows and highlights and other affects. Is there a way around this in the options?

I'm new to digital design so I never understood why designer not having autotrace is such a big deal, but it may be for this reason? Because then I could just convert the raster information to vector and be good to go, I'm assuming.

Check the export settings and see if you have the Rasterise setting set to Nothing – see attached image.
If it is, select a different setting.
If it’s not, or a different setting doesn't work, can you give us a screenshot of your export settings? (You may need to give more than one screenshot to get all of the settings as they sometimes don't all fit into the dialog at once.)

I attached a photo of my export settings. I was exporting on rasterize “unsupported properties” 

when I select “everything” I get a blank document, when I select “nothing” I get a image similar to that of unsupported properties which excludes raster elements.

You didn't initially told or indicated that you mean the iPad version here! - See therefor also "Affinity on iPad Questions" forum section.

Don't know if GarryP has/runs the iPad version too (?).

However, it's possible that something is bugy/broken on the iPad version for SVG export, thus somebody who uses that one too has to take a look and crosscheck here (...I for example don't use iPad versions, thus can't tell if something might be bugy there).

Oh sorry I just assumed these settings would be identical. 
 

But what you’re saying is this ain’t supposed to be happening? It kind of makes sense that SVG wouldn’t output raster elements, but then again I know knowing about file formats and how they behave.

AFAIK there are some differences between the desktop and iPad versions, the later does miss some options here.

Yes it shouldn't happen for the options settings you've tried out so far and have shown above. - The SVG format generally also supports embedded raster/pixel/bitmap images, such images will then be embbeded as base64 encoded image data text in the SVG code.

In Affinity the SVG export settings do control the SVG output generation code (how the SVG code will be written out then into a file). If you tell in the Affinity SVG export settings to "rasterize unsupported properties" than all that isn't handled by SVG's own vector commands (like specific pixel data for shadows and certain FX effects etc.) will usually be exported then as embbeded base64 pixel data into a SVG file. - But in your case it seems to does't do that here, which then will probably be a bug in the export generation code, or a no effect of an option setting here (meaning the options settings don't work correctly)!

Also when using the “everything” SVG export setting, it should usually export SVG code in your case which contains then vector + pixel data together. But you said it the does generate blank files (?). - BTW exported SVG code (so a SVG file) is just XML based text, which thus can be read and previewed with every text editor. So if you have some text editor on the iPad, you can tell that one to open the by Affinity generated SVG files here, in order to inspect their contents then. If there is any SVG code inside (SVG vector commands & base64 embbeded image data) it will be immediately obvious to you then!
