      In an effort to decease our page load time, we are looking at making a change so that all product images on any page past page 1 load with a place holder image.  When the user clicks to the next page, it then loads all of the images for that page.

      Right now, all of the product divs are loaded into a Javascript array and loaded in chunks to the page display div. Product-heavy pages significantly increase load time as the browser loads all of the images from the product HTML before the Javascript can rewrite the display div with page-specific product HTML. In order to get around this, we are looking at loading the product HTML with a small placeholder image and then substituting the appropriate product image URLs when each page is output to the display div.

      From a user experience, this change will be seamless and they won't be able to tell the difference, plus they will benefit from a potentially a short wait on loading the images for the page in question.  However, the source of the page will have all of the product images in a given category page all having the same image.  How much of a negative impact will this have on SEO?

        Are those images for search results (i.e. product thumbnails) or actual product pages? A link would help to understand how your site currently looks.

        If you have not done it yet, I would run you page through webpagetest.org (or pagespeed) and then look at obvious optimisations (CDN, HTTP cache directives, image-size optimisations) first.

        It sounds to me that you are "caching" multiple products in JS and based on user interaction show then the relevant content. Depending on how this is done, you might actually not get any SEO value from this.

          If it's Good for users it's good for Google.

          Potentially duplicate content < Fast page load speed + Lower Bounce Rate

            Reducing cumulative layout shift for responsive images - core web vitals

            core web vitals

            In preparation for Core Web Vitals becoming a ranking factor in May 2021, we are making efforts to reduce our Cumulative Layout Shift (CLS) on pages where the shift is being caused by images loading. The general recommendation is to specify both height and width attributes in the html, in addition to the CSS formatting which is applied when the images load. However, this is problematic in situations where responsive images are being used with different aspect ratios for mobile vs desktop. And where a CMS is being used to manage the pages with images, where width and height may change each time new images are used, as well as aspect ratios for the mobile and desktop versions of those. So, I'm posting this inquiry here to see what kinds of approaches others are taking to reduce CLS in these situations (where responsive images are used, with differing aspect ratios for desktop and mobile, and where a CMS allows the business users to utilize any dimension of images they desire).

            2 Menu links to same page. Is this a problem?

            One of my clients wants to link to the same page from several places in the navigation menu. Does this create any crawl issues or indexing problems? It's the same page (same url) so there is no duplicate content problems. Since the page is promotional, the client wants the page accessible from different places in the nav bar. Thanks, Dino

            Does an age verification home page hurt SEO?

            There's a microbrewery in our area that just launched its first website. It has the "verify your age" homepage (which is not really their homepage, but I don't know what it's called) before you can enter. It looks like this: http://angrychairbrewing.com/ Anyway, does this hurt them at all from a rankings standpoint? Also, assuming bots/spiders/ROGER can crawl sites like this, (which I think they would have to be able to do) how do they get around this verification? Thanks, Ruben

            Spaces at beginning of title tag - negatively affect the optimization of the page?

            For some reason, our title tags have a long space after the beginning title tag and before the text appears. The beginning title tag is on one line, then a break, a tab and then the content of the title tag.  I'm pretty sure this is not good and is affecting optimization of the page.  Am I correct or is this not an issue and does not need to be fixed? Example: | <title></span></p> <p> </p> </td> </tr> <tr> <td class="line-number"> </td> <td class="line-content">                       First keyword</td> </tr> </tbody> </table></title> |

            Is it bad for SEO if traffic is directed to "http://www.example.com/someuri/index.php" instead of "http://www.example.com/someuri/" and would it be works setting up a redirect rule at htaccess level?

            What is the best tool to view your page as Googlebot?

            Our site was done with asp.net and a lot of scripting. I want to see what Google can see and what it can't. What is the best tool that duplicates Googlebot? I have found several but they seem old or inaccurate.

            Pages vs. Posts for SEO

            Hi, I would like your thoughts about pages vs. posts for SEO. I understand the difference in terms of WP structure and have read the SEOmoz blog post about setting up your site for SEO success (http://www.seomoz.org/blog/setup-wordpress-for-seo-success). However, if you're trying to rank for a particular keyword, it seems that either one could work, from an on-page SEO perspective, as far as title tag, URL, meta description, etc. So how do you decide whether to set up a page vs. a post? What are the pros and cons, from an SEO perspective, about using one vs. the other? Thanks in advance! Carolina

            Footer Links Good or bad?

            Hi Can anyone answer this question confidently, I know Google is moving away from lots of links within the footer.  However we specialise in websites for the travel industry and having a link to all the areas at the footer can be quite handy.  Our websites complete this automatically. Here is an example where due to design of the site the links don't quite fit well, so we need to change anyway.  But before completing the work I wondered if there was a better way to do this. http://www.dreamvillasitaly.com/ Many thanks Andy
