Image Size for SEO
-
Hi there I have a website which has some png images on pages, around 300kb - is this too much?
How many kbs a page, to what extent do you know does Google care about page load speed? is every kb important, is there a limit?
Any advice much appreciated.

Yahoo's Smushit.it is a tool that can do some lossless compression on your images and may be of use. If you use Wordpress, there's also a smushit plugin that will compress your images on upload.
Page load speed does have an impact both for users and search engines. It's certainly something to consider.

Load time is absolutely a consideration in rankings, go into you google webmaster tools account and you can see your site performance and how your load time compares to other sites on the web. Images are just one aspect of why your page load times could be considered slow but it is a factor. Get the yslow extension for firefox and that will give you some suggestions about what other changes you can make on the site to reduce load times.
I would play around with optimizing your images in photoshop and see what percentage decrease you can get away with without noticing a difference. If all of your images are roughly the same quality you can do a batch in photoshop, which is basically making an action first, for example saying shrink all images by 15% and then batch all of the images in the image folder and photoshop will shrink them all in one shot.

Agree with Wayne, but for reference I'll have a large, good quality image at around 70kb and a standard image at around 20 - 30kb. If I can get it in for less without it looking terrible I will.
If you have photoshop it shouldn't be much of a problem playing with the save for web setting and seeing how much you can trim off. 60% is a good standard for jpg files.

Hi Paul,
I'm not 100% on the actual "size" of the image having any negative effects. In my experience it's directly related to how well the image is optimized. Yes, load time ABSOLUTLEY has an effect on rankings, and while some will say that it's a small effect, I contend that it's an important consideration.
While Google may not give it primary consideration in their algorithm, it can drive your users away as they wait for a page to load. People are going to wait a mere second or two before they back out of a page that is not loading. So bounce rate is the factor you need to weigh with regard to image size.
Other tips to optimize your image properly include, always add height and width to the image for faster loading, always add an Alt-attribute to the IMG-tag, always add a Title-attribute to the IMG-tag, etc.
Best of luck,
W

Craft CMS SEO Resources
I'm just starting out in freelance SEO & I've taken on a client who is using Craft CMS (version 2.0ish) for their site. I am not even close to being competent enough to manually code via Twig, but I had the main developer install the SEOmatic plugin for me. My question from here is - are there any resources or tips I should be aware of starting out? I just started by updating meta title/descriptions via "New Template Meta(s)" but I'm a bit concerned i'm doing the "template path" thing right - I haven't seen any visible changes in browser, and the SERP preview I'm getting is giving me a broken link. But i'm doing a fresh Moz crawl right now to see if the changes took place or not. so 1. Am I on the right track? 2. How long does it typically take for changes to start to show? 3. Is there anything I should be aware of? any follow up questions just let me know, I'll be following this thread!

SEO for sub domains
I've recently started to work on a website that has been previously targeting sub domain pages on its site for its SEO and has some ok rankings. To better explain, let me give an example...A site is called domainname.com. And has subdomains that they are targeted for seo (i.e. pageone.domainname.com, pagetwo.domainname.com, pagethree.domianname.com). The site is going through a site re-development and can reorganise its pages to another URL. What would be best way to approach this situation for SEO? Ideally, I'm tempted to recommend that new targeted pages be created - domainname.com/pageone, domainname.com/pagetwo, domainname.com/pagethree, etc - and to perform a 301 redirect from the old pages. Does a subdomain page structure (e.g. pageone.domainname.com) have any negative effects on SEO? Also, is there a good way to track rankings? I find that a lot of rank checkers don't pick up subdomains. Any tips on the best approach to take here would be appreciated. Hope I've made sense!

SEO multi-language ecommerce with Oscommerce
Hello Team, I have few things that have been bugging me for a while. I hired a SEO company, Just Search in Italy, to do the full campaign for me, both for Italian and French language. However, I'm a little puzzled over their suggestions: -for muti-language they suggested to use separate domains Sposae.com for Italian and Sposae.fr for French. I'm a little worried about this because this means that I would need to do double job every time we do any changes or updates to the website, because now we have two ecommerce software running. Right now I have on Sposae.com both languages, using the Ultimate SEO URL. My question to you all is do I really have to use different domains? The system I have now is really not good? Thanks a lot

Domain redirection and seo implications
We have an existing site that is a subdomain but we recently acquired an exact match domain. Will building links to the exact match domain and having the domain point at our existing subdomain work or should we convert the entire site and redirect our existing subdomain to the new domain? What I'm trying to figure out is how to maximize the benefit here and how the existing mass of links pointing to our existing subdomain (shop.domain.com) can be used. New domain: keywordshop.com Existing URL: shop.domain.com

SEO Info Bing - Logo and Name
I was reading the "How Search Engines Work" which is chapter 1 of the Beginners Guide to SEO by SEOMOZ. Came across an interesting point: "Don’t put the text that you want indexed inside images. For example, if you want your company name or address to be indexed, make sure it is not displayed inside a company logo." Surely most people will alt text their images with keywords or am i missing something here?
