We come across way too many websites that have been built by so called professionals that have neglected to setup even the most fundamental of website features or settings properly. Sometimes it blows my mind that they can still be in business! If these professionals are unable to get everything right, it is highly unlikely that you can on your own.
If you have ever tried this in the past and you were actually able to get everything done at a high standard, you may have enjoyed a pleasant feeling of achievement but you probably wasted a whole bunch of your time learning information that you only used once only to forget the next day. You should have spent your time working on your specialty and outsourced anything else that involved a steep learning curve.
