What is an open rate?
Open rate is a measure of how many people on an email list open (or view) a particular email campaign. The open rate is normally expressed as a percentage, and we calculate it as follows.

So a 20% open rate would mean that of every 10 emails delivered to the inbox, 2 were actually opened.
How do you measure an open?
When each email is sent out, we automatically add a piece of code that requests a tiny, invisible image from our web servers. So when a reader opens the email, the image is downloaded, and we can record that download as an open for that specific email. Read more
Project creep, as defined by Wikipedia, is:
“A problem in project management where the initial objectives of the project are jeopardized by a gradual increase in overall objectives as the project progresses.

In terms of web development, it’s the addition of features/tasks to a website, after the budget and specifications have been approved. Even small changes can add up to a substantial time allotment by the time a project is finished. This is work that is basically done “for free”, because the changes were outside of the budget created in the first place.

Maintaining a ‘blog’ or news section on your website is a great way of updating customers about news, views and events from your business or industry. Not to mention it’s very search engine friendly and will keep your website well ranked (and therefore found) in Google and other search engines.
If you have a five page site and no blog, then you have five chances to rank in search engines. If you have a five page site and a blog with hundreds of posts, you have hundreds of chances to rank. A recent survey suggests that companies who blog receive 97% more inbound links than those who don’t. Inbound links are important because they signal authority to search engines, thus increasing your chances of getting found in those search engines. Read more
