FILE SIZE

"Number three, I want you to check the size of your files. We don't want any large or necessarily large files slowing down your website. So you can come over to the files area. Now, top tip is if you sort by file size largest, so I'm going to do this in click search, and what you'll see is the largest files appear at the top. Well, as you know, on mobile when you upload a JPEG, we're compressing that down. Now we're aiming for below 200 kb or as close as we can to get there. Now if this is over 300 kb, this won't be blue, it'll be red saying to you, "Can you do something about that image?" Maybe you'll make it a bit smaller, or maybe you forgot to turn on the compression when that image was uploaded. Now, as you know, you can go and change the compression over in the global settings area, and we often see that if, sometimes, some users have turned that off and they'll upload a five megabyte image and they forget to turn the compression back on.

So top tip there, check your file sizes and make sure that's running. Now if you have got a large image that's above 300 kb, it's most likely one of three things. One, like I've said, someone's turned off the compression and forgot to turn it back on, then uploaded an image so it hasn't compressed. Number two is it's a PNG file. Now we do attempt to compress PNGs, but remember their graphic files. So JPEGs are your images and PNGs are graphic files maybe for your logo with a transparent background. So we do compress those as well. But the key tip here is make sure that if you have got an image, you've actually uploaded a JPEG and not a PNG, those PNGs will be larger and Google will penalize you if you're using PNGs rather than JPEGs for your images.

And the third is PDFs. Well, you don't really want to compress a PDF so often. We'll know not to compress that when you upload a PDF, but the PDF could actually be quite large. So one of the episodes we looked at files in the end, very end, of day two, well, when we're... if you put a PDF into a widget, will automatically put the lazy loading on that anyway, so it won't start loading until the user gets to that particular point in the webpage, making sure your site is optimized just naturally and organically. Okay so let's move on to number four."
