Read these answers knowing that this is what I do and how I think. On lots of these answers I don't know what google does and what google prefers. I am betting on my gut rather than on something that somebody somewhere said sometime in the past which might be very different now. I only trust what a very small number of people say and realize that google changes their mind about lots of stuff that they said in the past and don't tell anybody anything.
Make sense? lol
Currently it's "How To: Build a Custom Ergonomic Computer Desk - Blog - Projects, Ideas, Inspiration, Kee Klamp, Fittings"
I'd say that is waaaayyyyy too long. I keep mine at about 62 characters or less. Without doing a detailed analysis of traffic that the page is currently pulling I would probably shorten to...
How To: Build a Custom Ergonomic Computer Desk
What about changing the image file names and adding alt tags when they are nonsense or garbage?
Lots of my pages get over half of their traffic from image search. I would not change the image file name or the alt attribute unless I thought that there was a significant upside.
These can be part of the optimization of the page.
I do replace images when I have something better or update a graph, map or photo. However, I always maintain the file name and alt attribute.
Sometimes content update requires images to be deleted and I do that with reluctance.
OMG!
My image tags look like this....
"keyword" is something simple... probably two or three absolutely relevant keywords that describe the image.
giving the files real names and putting them on my own CDN
All of my images are on the same server as the website, in the same folder as the article.... like this...
egolsite.com/article-name/image-name.jpg
Some people have told me to move my images to cloud hosting or a free service instead of my server but I don't want to make it look like I am not serving my own content. I don't know if that makes any difference at all but I gladly pay to transfer terrabytes of images per month to keep them on my own servers. If someone hotlinks one of my images does that help my domain's authority? I don't know... but I got 'em there where I can see what's happening.
But what if I wanted to add a nice "finish" picture to to the top? Would that cause any issues?
I assume you are talking about a nice big image at top of page that will make visitors salivate? If that is what you are talking about then I would say... do it by all means and do it often.
What about making these changes incrementally?
Don't fart around. Go for it.
