Which type of logo would best suit my company?
There is no one type of logo that works for everyone. Which fits you best depends a lot on your name and what you provide or make.

For example, if you have a short company name, a wordmark logotype could work well. Wordmarks and letterform logos generally help consumers remember your name better than abstract logos. If you opt for an abstract symbol, however, be sure it’s straightforward and mirrors the personality of your brand.

Are you going to be transferring this logo to white background, or black background, or both?

Make sure your logo is going to transfer to a white or black background (whichever you choose) easily. You will want it to be completely legible and very clear, on whatever platform you choose to use it.
