      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

                Domain Masking SEO Impact

                I hope I am explaining this correctly. If I need to provide any clarity please feel free to ask. We currently use a domain mask on an external platform that points back to our site. We are a non-profit and the external site allows users to create peer-to peer fundraisers that benefit our ministry. Currently we get many meta issues related to this site as well as broken links when fundraisers expire etc. We do not have a need to rank for the information from this site. Is there a way to index these pages so that they are not a part of the search engine site crawls as it relates to our site?

                Do long UTM codes hurt SEO?

                Since most UTM codes/URLs are longer than 70ish characters, is this hurting my SEO? If it is, how can I solve the problem while still using a UTM code? Thanks!

                Express js and SEO?

                Hi fellow Mozzers, I have been tasked with providing some SEO recommendations for a website that is to be built using express.js and Angular.  I wondered whether anyone has had any experience in such a framework? On checking a website built in this and viewing as a GoogleBot etc using the following tools it appears as though most of the content is invisible: http://www.webconfs.com/search-engine-spider-simulator.php http://www.browseo.net/ Obviously this is a huge issue and wonder if there are any workarounds, or reccomendations to assist (even if means moving away from this  - would love to hear about it)

                Loading images below the fold? Impact on SEO

                I got this from my developers. Does anyone know if this will be a SEO issue? We hope to lazy-load images below the fold where possible, to increase render speed - are you aware of any potential issues with this approach from an SEO point of view?

                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 rss feeds help seo?

                If we put relevant RSS feeds on a site, will it help the SEO value? Years ago, I shied away from RSS feeds because they slowed the site down and I didn't like relying on them. However, the past couple years, the Internet has become better, especially in Alaska.

                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!
