How do I know I'm keywords stuffing?

I recommend you to use two to four word key phrases not to exceed 12 keywords, more than 12 is keyword stuffing by google's standards, as I know. Don't blend your keywords with the background of the page, so vizitors won't see it, but google will.

A lot of SEO guys and gals around here would say yes, img titles and (especially) alt text is a good place to put your main keyword.

But, you said 'Does entering them into the titles...' which makes me think that you want to throw a bunch of keywords into titles and alts. I would not recommend that. The alt element is meant to describe the contents of the image on a page, in case a user's browser doesn't display images or they are visually impaired. Google still wants you to use it for this purpose.

You can get away with putting one keyword into an alt text, but I wouldn't recommend two or three. Google will want you to use the longdesc element for a description that has many words.

YES - put your keywords into your page title. But, don't go crazy. Google search cuts off the title after 64 or so characters. So, you should use your title real estate wisely. Use something like 'Main Keyword - Description of content - Synonym/Secondary Keyword'.

Keeping your main keywords at the front will ensure that search engine users will be able to see the keyword and if they searched for that keyword specifically, it will show up in bold.

As far as keyword density in your page content, I would personally recommend keeping your keywords as about 2% of your page content or less. That's what I have had the most success with - I think that if you go higher, Google kind of thinks that you're trying to stuff your page with keywords.

Try to use a tool like Traffic Travis to analyze your pages for SEO. Traffic Travis gives great suggestions - even goes into what you use as h1 and h2 tags and META tags, etc...

Good luck. Hope that helps.

Sorry is I'm coming off obtuse. I just am genuinely new. But let's say I've got a site about how to keep your kitchen tidy and I make all of my image alt text something with the words keep your kitchen tidy

e.g. This cloth will keep your kitchen tidy
Keep your kitchen tidy with this awesome spray
Even your dog can be used to keep your kitchen tidy

and so on.

It's relevant, but by your recommendation this would be a bad idea right?

Wow this SEO stuff is going to take me ages to learn, Haven't even touched on backlinks, etc yet!I guess this is why people hire experts but I'd really like to have some understanding first!

no that would not be appropriate..you should accurately describe each image what they are really about and use important keywords..so on the title of course you need it to as well as other strategic places on the page..
