Due to the fact that most researching, fact checking and first impressions are done online, you don't want to risk being "scrolled over"!
So, if you're brand is established, make sure you're all set with the list below. If not, reach out to someone that can do it for you, or heck, gimme a shout. Afterall, that's what I'm hear for! As part of my Biz-Startup Package, all the items in this list are standard.
1. Your LOGO
Multiple file types/formats of your logo to accomodate print and web
2. An AVATAR
The little image/profile pic that is shown next to a screen name on a social media site
3. Facebook COVER IMAGE
The banner graphic that sits behind your profile pic. and spans the width of the page.
4. Twitter COVER IMAGE
Pretty much the same thing as a Facebook cover image.
5. Newsletter HEADER
For e-blast/virtual newsletter's. Think of this like the header on stationary.
6. Web AD
If applicable, of course. A small graphic that meets the required dimensions and layout for the location online.
7. "Sharing" IMAGE TEMPLATE
If applicable. Watermark image representative of your brand or logo to place on top of images should someone want to use them without obtaining the proper rights to use.
