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

SEO Problems with Loading to a Subfolder?
A client has a single page app website that shows https://example.com/example when you visit https://example.com . I don't think this is a redirect; I think it's a URL rewrite. My questions: Is this setup common with single page apps? What are the SEO benefits or drawbacks of having a domain's homepage load, rewrite, or redirect to a subfolder?

SEO for a a static content website
Hi everyone, We would like to ask suggestions on how to improve our SEO for our static content help website. With the release of each new version, our company releases a new "help" page, which is created by an authoring system. This is the latest page: http://kilgray.com/memoq/2015/help-en/ I have a couple of questions: 1- The page has an index with many links that open up new subpages with content for users. It is impossible to add title tags to this subpages, as everything is held together by the mother page. So it is really hard to for users to find these subpage information when they are doing a google search. 2- We have previous "help" pages which usually rank better in google search. They also have the same structure (1 page with big index and many subpages) and no metadata. We obviously want the last version to rank better, however, we are afraid exclude them from bots search because the new version is not easy to find. These are some of the previous pages: http://kilgray.com/memoq/2014R2/help-en/ http://kilgray.com/memoq/62/help-en/ I would really appreciate suggestions! Thanks

Static or dynamic category pages for seo
Hi, I'm developing an accommodation site with a limited number of properties in 8 categories. I had been looking at making the properties blog posts and then using category function to show lists but its going to require a lot of customisation and I have seo concerns about the dynamic content as the category page is crucial. As I don't have a lot to add and listings will remain the same my latest thought was to create all as pages. However if I create a page with a list of 12 properties on a category page is there anyway of adding some sorting criteria to that page (would be 7 options - swimming pool, near beach, on site creche, budget, mid-range, luxury) Thanks for any tips Neil

SEO Ultimate’s and Yoast together
We are using SEO Ultimate’s and Yoast together on a Wordpress website, does anyone have negative experience by using this to plugins together? The main result to use this, is because we could remove the /product/ from the slug. We want clean URL’s and not URL’s that have: website.com/product/PRO1 or website.com/product-catagory/CAT2 (standard Wordpress) But we want: website.com/PRO1 or website.com/CAT2 In Yoast is possible to remove the URL /category/, but not the /product/. With SEO Ultimate’s it is possible. So we use them both. SEO Ultimate’s for the removal of the URL, and Yoast for it’s great functions: Sitemap, no index /page2/, no index media etc. etc. But Yoast gives the following note: ‘’WordPress SEO (Yoast) is known to cause conflicts with SEO Ultimate. Please deactivate WordPress SEO if you wish to continue using SEO Ultimate.’’ I was wondering what this could mean for overal SEO performance. And maybe there is a way to remove the URL’s by using other methods > and remove the SEO Ultimate’s plugin.

What's the correct SEO for a Gallery?
Hi there, I was wondering if anyone was an expert on galleries and using canonical URL's? URL: http://www.tecsew.com/gallery In short I'm doing SEO for a site and it has a large gallery (3000+ images) where each specific image has it's own page and each category (there's 200+) also has its own page. Now, what I'm thinking is that this should be reduced and asking Google to index/rank each page is wrong (I also think this because the quality of the pages are relatively low i.e little text & content etc) Therefore, what should be suggested/done to the gallery? Should just the main gallery categories get indexed (i.e http://www.tecsew.com/3d-cad-showcase)? Or should I continue to allow Google to trawl through all of it? Or should canonical URL's be used? Any help would be greatly appreciated. Best Wishes, Charlie S

The best way to organize a gallery for SEO?
I need to redo the following gallery
Technical SEO | | UnderRugSwept
http://goo.gl/PFvjE
because besides the fact that it looks ugly, it's an SEO mess. Since all the pages are comprised of images, and the only text is the navigation, I'm getting duplicate content issues. I tried adding a little paragraph of text on some of the pages, but this thing needs a total revamp. My main question is this: is that menu being repeated on all the pages really a good thing? What good is it to, say, on the fire patches page, to have a menu that includes all these keywords for sports patches? Would it be better to just have a main gallery page that lists the main patch types: applique, motorcycle, Scouting, ect, and then once you get to that page, list all the different sub categories?0
