Decreasing Page Load Time with Placeholder Images - Good Idea or Bad Idea?
-
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
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).

Reason for robots.txt file blocking products on category pages?
Hi I have a website with thosands of products. On the category pages, all the products are linked to with the code “?cgid” in the URL. But “?cgid” is also blocked in the robots.txt file for some reason. So I'm thinking it's stopping all my products getting crawled by Google. Am I right here? Is there any reason why a website would want to limit so many URL's? I'm only here a week and the sites getting great traffic, so don't want to go breaking it!!! Thanks

Dead end pages are really an issue?
Hi all, We have many pages which are help guides to our features. These pages do not have anymore outgoing links (internal / external). We haven't linked as these are already 4th level pages and specific about particular topic. So these are technically dead end pages. Do these pages really hurt us? We need to link to some other pages? Thanks

Side bar menu, good or bad idea.
Hi everyone, I have a little problem. Not that long ago I launched my new site. Everything seems ok, but I'm not sure if it was clever idea to have additional side bar menu option. I wanted relevant content to be accessible very easy without dropdown in main menu. It looks ok on desktop, but we have a problem with mobile devices. Even main menu is a bit confusing and sidebar at the moment is at the bottom of each page. When I placed it on top of the page, we had problem with tablet users as it is showing side menu with blank page and content is almost below the fold. I have a tool installed called usability tools and it shows how visitors are using my site. The hard bit is that nobody on mobile devices are using sidebar and that means people visit one page and leave without exploring any additional resources. Me and my developer are discussing that maybe we should have two main menu bars instead of sidebar, but I have no idea how this looks in real life. What is the best practises for sidebar menus these days? Maybe we have a designer here who can help me with this and do some work? My site is https://a-fotografy.co.uk/ Thank you for all help in input in advance. Regards, Armands

Is placing an H1 tag below a slideshow a bad practice?
Hello All, It is to my understanding that it is a best practice to have a single H1 headline that corresponds to your title tag at the top of your page, above your content for the best On-Site Optimization. We are developing a site that uses a big slideshow with text on each slide, and are concerned that placing the H1 Headline below this will be a bad practice. Would a better option be to have the slide show text on the image and place no alt tags on the slides, so that the crawlers accessing the page overlook this and see the H1 below the slider first? We need to maintain the slider for design purposes, but would like the site to optimized. A similar example to what the slider will look like is as follows: http://www.boviskyle.com/ However, we look to have optimized, "10x" content below the slider with a solid H1 headline as well. Thank You!

WIX? is it any good for SEO
Hi people. I have just built my website www.bellagiolimousines.com.au using WIX. I am in the process of optimising for SEO, and after reading a couple of older posts i.e 2012; I read that some SEO consultants do not like WIX. However with their recent upgrades, I was hoping if anyone else has had any recent experience with WIX? I have spent a considerable amount of time building this site, and I don't want to waste anymore time in optimising it, if I am not going to receive a top 3 organic SERP. Hope to hear from someone real soon!

How to Add canonical tags on .ASPX pages?
What is the proper way (or is it possible) to add canonical tags on website pages that end in .aspx? If you add a canonical tag to the Master Page it will put that exact canonical tag on every page, which is bad. Is there a different version of the tag to put on individual pages? And one to put on the home page without the Master Page error?
