Website speed is a topic that is pretty important. The main reason your website needs to be fast is to keep visitors from leaving. If your website does not load in a few seconds (2-4) visitors will most likely move on. Page speed has also been linked to Google ranking. It is one of their ranking indicators, how much of a factor it really is, is unknown (at least to me). When it comes to page speed I am thinking about the user experience, not so much Google.
The biggest mistake I see is users often upload massive images to their websites. No image should have an “MB” after the number. They should all be in low “kb” size. For example your website logo should only be about 20kb. The slider image should be no more than 300kb.
The homepage design is also very important. Try and leave off any scripts to 3rd party tools from your homepage. For example do not put a google map, a review widget, or mortgage calculator. These items typical have to reach out to another server to load. Which will worsen your website time. Keep the design clean and easy to read. Clutter has no place on websites. Do not be a homepage hoarder.
In the video attached to this article I go through exactly I review website speed and what to look for in the reports you can generate. We use GTMetrix to test our websites. Feel free to try it, it is free.
