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).

@seoelevated
Hi,
I am facing issue of higher cumulative layout shift. The reason behind this is that I am loading css script at the end once complete page is rendered (in order to reduce page loading time. So page loading time is reduced on the cost of higher cumulative layout shift. I am new in SEO. Kindly suggest me, for improved google search ranking, whether it will matter and whether I should load css at the start itself for reducing cumulative layout shift. Also, being a pin code finder website, texts are limited only. Should I add more text in webpages for improved ranking. (for reference, the website is https://pincodeinfo.online ) -
I'm in the same exact situation as well! Feels like we are kind of stuck as I also have different aspect ratios for device and use a CMS that has a lot of limitations.

Sudden Drop in Mobile Core Web Vitals
Web Vitals Screengrab.PNG For some reason, after all URLs being previously classified as Good, our Mobile Web Vitals report suddenly shifted to the above, and it doesn't correspond with any site changes on our end. Has anyone else experience something similar or have any idea what might have caused such a shift? Curiously I'm not seeing a drop in session duration, conversion rate etc. for mobile traffic despite the seemingly sudden change.

My news site not showing in "In the news" list on Google Web Search
I got a news website (www.tapscape.com) which is 6 years old and has been on Google News since 2012. However, whenever I publish a news article, it never shows up "In the news" list on Google Web Search. I have already added the schema.org/NewsArticle on the website and have checked it if it's working or not on Google structured data testing tool. I see everything shows on on the structured data testing tool. The site already has a news sitemap (http://www.tapscape.com/news-sitemap.xml) and has been added to Google webmaster tools. News articles show perfectly fine in the News tab, but why isn't the articles being shown on "In the news" list on the Google web search? My site has a strong backlink background already, so I don't think I need to work on the backlinks. Please let me know what I'm doing wrong, and how can I get it to the news articles on "In the news" list. Below is a screenshot that I have attached to this question to help you understand what I mean to say. 1qoArRs

Https pages indexed but all web pages are http - please can you offer some help?
Dear Moz Community, Please could you see what you think and offer some definite steps or advice.. I contacted the host provider and his initial thought was that WordPress was causing the https problem ?: eg when an https version of a page is called, things like videos and media don't always show up. A SSL certificate that is attached to a website, can allow pages to load over https. The host said that there is no active configured SSL it's just waiting as part of the hosting package just in case, but I found that the SSL certificate is still showing up during a crawl.It's important to eliminate the https problem before external backlinks link to any of the unwanted https pages that are currently indexed. Luckily I haven't started any intense backlinking work yet, and any links I have posted in search land have all been http version.I checked a few more url's to see if it’s necessary to create a permanent redirect from https to http. For example, I tried requesting domain.co.uk using the https:// and the https:// page loaded instead of redirecting automatically to http prefix version. I know that if I am automatically redirected to the http:// version of the page, then that is the way it should be. Search engines and visitors will stay on the http version of the site and not get lost anywhere in https. This also helps to eliminate duplicate content and to preserve link juice. What are your thoughts regarding that?As I understand it, most server configurations should redirect by default when https isn’t configured, and from my experience I’ve seen cases where pages requested via https return the default server page, a 404 error, or duplicate content. So I'm confused as to where to take this.One suggestion would be to disable all https since there is no need to have any traces to SSL when the site is even crawled ?. I don't want to enable https in the htaccess only to then create a https to http rewrite rule; https shouldn't even be a crawlable function of the site at all.RewriteEngine OnRewriteCond %{HTTPS} offor to disable the SSL completely for now until it becomes a necessity for the website.I would really welcome your thoughts as I'm really stuck as to what to do for the best, short term and long term.Kind Regards

Should i not use hyphens in web page titles? Google Penalty for hyphens?
all the page titles in my site have hyphens between the words like this: http://texas.com/texas-plumbers.html I have seen tests where hyphenated domain names ranked lower than non hyphenated domain names. Does this mean my pages are being penalized for hyphens or is this only in the domain that it is penalized? If I create new pages should I not use hyphens in the page titles when there are two or more words in the title? If I changed all my page titles to eliminate the hyphens, I would lose all my rankings correct? My site is 12 years old and if I changed all these titles I'm guessing that each page would be thrown in the google sandbox for several months, is this true? Thanks mozzers!

What seo benefit does setting up a photo gallery where each photo is a separate web page?
what seo benefit does setting up a photo gallery where each photo is a separate web page? My old SEO guy set up my photo gallery like that claiming that because each photo was a separate page, it added a big seo benefit and i never understood what he was talking about. Maybe alt text on the photo with key phrases in it pointing to my other pages to give my site a theme for google? I'm not really sure. He has since moved away and i am considering redoing the photo gallery to multiple images on one page to be more user friendly to my users. This photo gallery is 3 years old and the photos might have some page rank to them helping my site so i don't want to remove this gallery if there really is a benefit to it and it will hurt my site. I once removed four static page rank 3 pages from my site that weren't used for my site anymore and my rankings dropped 5 positions. Thoughts anyone? Thanks! Ron

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?
