I would say one of my main problems is getting the words into code. I feel i’ve gotten better just by breaking it down into even smaller problems. I have yet to have a project im disappointed in, reason being i’ve usually always proud of what i have done. I don’t come from a tech family or even a family with high degree holders. So i always am proud of things i do that i never thought i would as a youngster. SEO is a bit confusing i need to ask JON about this one.
Making a site mobile friendly is one of the main things, but i do feel it goes back to file structure, user experience, speed, how accessible is your APP or Website.
