    Hi guy's,

    I came across webshops that put images, CSS and Javascript on different websites or subdomains. Does this boost SEO results? On our Wordpress webshop all the sourcescodes are placed after our own domainname:

    www.ourdomainname.com/wp-includes/js/jquery/jquery.js?ver=1.11.3'
    www.ourdomainname.com/wp-content/uploads/2015/09/example.jpg

    Examples of other website:

    Website 1:
    https://www.zalando.nl/heren-home/

    Sourcecode:

    https://secure-media.ztat.net/media/cms/adproduct/ad-product.min.css?_=1447764579000

    Website 2:

      The only major improvement I can think of hosting images externally would be improving the overall speed of your website. If you run a pagespeed test with Google's free tool and notice your site is rendering slow then I would first consider reducing the number of javascript and css files being loaded. You will run into issues if your site is loading too many external files you can expect to see increases in bounce rates and poor engagement metrics. This may have changed but Moz did an expierement awhile back on if website speed impacts search ranking however if certain pages are taking too long to load they probably

      This may have changed but Moz did an experiment awhile back on if website speed impacts search ranking. Even if speed does not directly impact rankings if certain pages are taking too long to load they probably won't be indexed.

      What I would do is run Google's page speed tool on a few pages and if you have Google analytics on your site you can get some insights by looking at Behavior-> Site Speed-> Speed Suggestions and check out some of the recommendations Google is making about your site.If you have a problem with

      If you find out that you have a problem with speed I came across a good article on some tips and suggestions that may be helpful for you about reducing http request.

      I hope this helps some.

        Moz crawler is not able to crawl my website

        moz crawler

        Hi, i need help regarding Moz Can't Crawl Your Site i also share screenshot that Moz was unable to crawl your site on Mar 26, 2022. Our crawler was not able to access the robots.txt file on your site. This often occurs because of a server error from the robots.txt. Although this may have been caused by a temporary outage, we recommend making sure your robots.txt file is accessible and that your network and server are working correctly. Typically errors like this should be investigated and fixed by the site webmaster.
        my robts.txt also ok i checked it
        Here is my website https://whiskcreative.com.au
        just check it please as soon as possibe

        Images on sub domain fed from CDN

        I have a client that uses a CDN to fill images, from a sub domain ( images.domain.com). We've made sure that the sub domain itself is not blocked. We've added a robots.txt file, we're creating an image sitemap file & we've verified ownership of the domain within GWT. Yet, any crawler that I use only see's the first page of the sub domain (which is .html) but none of the subsequent URL's which are all .jpeg. Is there something simple I'm missing here?

        Removed Product page on our website, what to do

        We just removed an entire product category on our website, (product pages still exist, but will be removed soon as well) Should we be setting up re-directs, or can we simply delete this category and product 
        pages and do nothing? We just received this in Google Webmasters tools: Google detected a significant increase in the number of URLs that return a 404 (Page Not Found) error. We have not updated the sitemap yet...Would this be enough to do or should we do more? You can view our website here: http://tinyurl.com/6la8 We removed the entire "Spring Planted Category"

        Robots.txt on subdomains

        Hi guys! I keep reading conflicting information on this and it's left me a little unsure. Am I right in thinking that a website with a subdomain of shop.sitetitle.com will share the same robots.txt file as the root domain?

        Best Practice on 301 Redirect - Images

        We have two sites that sell the same products. We have decided to retire one of the sites as we'd like to focus on one property. I know best practice is to redirect apples to apples, which in our case is easily done since the sites sold the same thing. www.SiteABC.com/ProductA can be redirected to www.SiteXYZ.com/ProductA. My question is how far does that thinking go regarding images? Each product has a main product page, of course, and then up to 6 images in some cases. Is it necessary to redirect www.SiteABC.com/ProductA-Image1.jpg to www.SiteXYZ.com/ProductA-Image1.jpg? Or can they all be redirected to just the product page?

        What happens when you put an image in an H1 tag?

        I am currently updating some H1 tags for my site but the tags are generated automatically by the text that is entered into a field on our content manager software. However because we need an image in this area as well, the entire field including the code for the image is surrounded by an H1 tag. Is this bad for SEO?

        Why are old versions of images still showing for my site in Google Image Search?

        I have a number of images on my website with a watermark. We changed the watermark (on all of our images) in May, but when I search for my site getmecooking in Google Image Search, it still shows the old watermark (the old one is grey, the new one is orange). Is Google not updating the images its search results because they are cached in Google? Or because it is ignoring my images, having downloaded them once? Should we be giving our images a version number (at the end of the file name)? Our website cache is set to 7 days, so that's not the issue. Thanks.
