Without seeing the SVG, it's hard to say, but here are some possibilities:
Did you drew outside the drawing area?
Open the file and press Ctrl+Shift+D. There's an option to re-size based on the drawing.

While the latter lets you create a text box that wraps, it's not a standard SVG feature and many browsers ignore it.
To fix it select the object. Then, on the Text menu, click Convert to text.
Convert the text to path
It's important to note that SVG files do not embed fonts. If the user doesn't have the font, it may be replaced in ways you wouldn't expect. For things like logos, you definitely don't want your font to be substituted.
The solution is to convert the text to a path. Select the object. Then on the Path menu, click Object to Path.
You will no longer be able to edit the text, but it will be rendered by browsers exactly as you see it. If you use the Node tool F2 and hover over the letters, you'll see that the are all now individual paths.
If you have an image where you might want to edit text later, but also want to convert to paths, you don't need to save two separate files (although that works too). What I sometimes do is save the text in a separate layer. When I want to convert everything to paths, I duplicate the text layer, convert it, then hide the original. This way, I can still keep the text if I need to edit it later.
