Always Always edit your plan. Misspelled words and number errors will certainly not impress your readers. Always run a Web plan through a final edit. Have you run your spellcheck software? Have you read it over again? Do you have some friends who can read it for you? Sometimes you don't see the errors that others would see because you are too close to it.
Check the numbers in your charts and tables. Make sure they match each other, and go back and check the references to numbers in the text. People often change numbers after writing objectives, which results in conflicting information. For example, your objectives text might set sales objectives of $500,000, but your plan tables show sales projections of $400,000.
If you can, tighten your text. Shorten it, get to the point, make it sharper.
