      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

                Not all images indexed in Google

                Hi all, Recently, got an unusual issue with images in Google index. We have more than 1,500 images in our sitemap, but according to Search Console only 273 of those are indexed. If I check Google image search directly, I find more images in index, but still not all of them. For example this post has 28 images and only 17 are indexed in Google image. This is happening to other posts as well. Checked all possible reasons (missing alt, image as background, file size, fetch and render in Search Console), but none of these are relevant in our case. So, everything looks fine, but not all images are in index. Any ideas on this issue? Your feedback is much appreciated, thanks

                Is Base64 encoding images in general better for SEO or worse?

                We've made a lot of changes to our website (https://refreshcartridges.co.uk/) over the years, with our website developer putting a heavy emphasis on improving page loading times in general. One of the those changes has been to base64 encode or in-line the majority of images on our site which has reduced our loading times down to under a second for most of our pages for our visitors which are mainly based in the UK. My question is whether in-lining the images, thus removing the images filenames for index association results in this technique being a net-good or net-bad for our sites SEO in general, particularly on our frontpage.

                Schema for Banks and SEO

                I'm researching Schema opportunities for a bank, but besides the shema markup available today (like bankorcreditunion) and developments with FIBO, I can find no answer as to the effect of tagging interest rates and such in terms of SERP/CTR performance or visibility. Does anyone have a case study to share or some insight on the matter?

                How do you build your pre-sales seo audit

                Hello Moz community, I'd like to know if you build "pre-sales seo audit" when selling your services to a prospect. I think the main idea of a pre-sales audit is to show your prospect that you understand his industry (trends & competition) understand the opportunities know the roadblocks on his website If so, i'd be interested in discussing the information you put into your pre-sales audit and how you organise it. If you know ressources i should read as regards to mini seo audit / pre-sales seo audit just paste the link 🙂 Thanks for your answers

                Do Abbreviations Hurt SEO Results?

                We have certain products that we've abbreviated since it's a bit too long.  For example, the word Fair Trade Organic is one of our categories and we abbreviate it to FTO. If I put FTO  on our meta tag titles and links instead of the actual word, would that provide a weaker result?

                Do the search engines penalise you for images being WATERMARKED?

                Our site contains a library of thousands of images which we are thinking of watermarking.  Does anyone know if Google penalise sites for this or is it best practice in order to protect revenues? As watermarking these images makes them less shareable (but protects revenues) i was thinking Google might then penalise us - which might affect traffic Any ideas?

                What are your best tips for SEO on a shopping cart?

                So, I am working on a shopping cart platform (X-Cart) and so far don't like it. Also, the web designer is not someone I've worked with before and he is understandably conservative about access--which limits what I can and cannot do from the back end. One of the things I like to do is include text for the search engines. However, based on conversion, etc., I think the product images on a landing page (main brand info with specific products that show up) should show up first to move toward conversion first. I am thinking of adding the text below the product images on the brand pages so the viewer sees the products first while still keeping the content seo. My practice is to use between 300-350 words minimum on a page. Just wondering what best practices you have for a shopping cart. Care to share? Any tips or hints? Thoughts on what I might do that would be most effective? As always, thanks in advance for your sage advice!
