      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-i3.ztat.net//camp/03/d5/1a0168ac81f2ffb010803d108221.jpg
      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.

          Redirecting an Entire Website?

          redirecting domain redirect former site

          Is it best to redirect an old website to a new website page by page to like pages or just the entire site all at once to the home page of the new site? I do have about 10 good pages on the site that are worth directing to corresponding pages on the new site. Just trying to figure out what is going to preserve the most link juice. Thanks for the help!

          My website is constantly decreasing

          loss of ranking

          For few weeks ago my website is constantly decreasing in search position. I lost keywords and is gooooing down.
          Although it is well rated on several on page and off page seo verification software that I have tried.
          I checked Google search console and Analytics and found no major problems. However… from one day to another it keeps going down.
          I also checked what the main competitors are doing and they are not doing well, at all.
          The main competitor actually has a creepy website. Totally devoid of onpage or offpage SEO but with an enormous number of backlinks. And of a very bad quality, which should disqualify it, still…
          Few weeks ago I changed something.
          In the pages I had H1, 4xH2, no H3 and an H4 without content.
          An unnatural H tag structure.
          Now I have H1, H2, H3, 3xH4, with the coherent information.
          Theoretically, Google should have been “happy” or I’m missing something. I use a SAAS platform.
          I just found out that they made changes to the keywords (tags).
          I am selling toner cartridges for printers.
          So…
          The tags are printer models and generate a url in which they have the products.
          Ex. https://www.sertit.ro/cartus-imprimanta-cilindru-color-hp-laserjet-pro-m-177fw goes to the products for that printer model.
          The question is… should I make tag canonical?
          Is it possible for products to loose so much in Google search?

          Measuring the size of a competitors website?

          I think our website is too big, far too many indexed pages. I'd like to do some research on how big our competitors' websites are (how many indexed pages). Is there a way to do this? Cheers, Rhys

          Is it important to include image files in your sitemap?

          I run an ecommerce business that has over 4000 product pages which, as you can imagine, branches off into thousands of image files. Is it necessary to include those in my sitemap for faster indexing? Thanks for you help! -Reed

          Dynamically changing a title with javascript

          Hi, I asked our IT team to be able to write custom page titles in our CMS and they came up with a solution that writes the title dynamically with javascript. When I look on the page, I see the title in the browser, but when I look in the source code, I see the original page title. I am thinking that Google won't see the new javascript title, so it will not be indexed and have no impact on SEO. Am I right ?

          Image search and CDNs

          Hi, Our site has a very high domain strength.  Although our site ranks well for general search phrases, we rank poorly for image search (even though our site has very high quality images). Our images are hosted on a separate CDN with a different domain.  Although there are a number of benefits to doing this, since they are on a different domain, are we not able to capitalize on our my site's domain strength?  Is there any way to associate our CDN to our main site via Google webmaster tools?  Has anyone researched the search ranking impacts due to storing your images on a CDN, given that your domain strength is very high? Curious on people's thoughts?

          If a redirecting URL has more value than the website should I move it?

          Client has two website addresses: Website A is a redirect to Website B. It has one indexed page. But this is the URL being used in collateral. It has the majority of back links, and citations everywhere list Website A as the URL. Website B is where the actual website lives. Google recognizes and indexes the 80+ pages. This website has very few backlinks going to it. This setup does not seem good for SEO. Moreover, the analytics data is completely messed up because Website B shows that the biggest referral source is... you guessed it Website A. I'm thinking going forward, I should: Move all the content from Website B to Website A. Setup Website B to permanently 301 Redirect to Website A. Is that the best course of action?
