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.

Image with 100% width/height - bad ranking?
Hi, we have some articles like this: http://www.schicksal.com/Orakel/Freitag-13 The main image has a width of 100% and a height of 100%. Today, I've discovered that GWT Instant Preview has some troubles with rendering the page. We have CSS rules to deliver the image with the right dimensions. If a bot like google is not sending any screen height / width we assume the screen size is 2560x1440. Does this harm the ranking of the page? (Content starts below the fold/image) What is a "default" screen size for google? How do they determine if something is "above the fold"? Any tips or ideas? Best wishes, Georg.

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!

Replacing Slider Image WordPress
Hi Everyone, I decided to delete my slider from my homepage and replace it with a static image. However, after I deleted the slider, I'm left with a dark square where the slider used to be. I want to put my new static image in that same spot, but have no idea how. Does anyone know where or what code I should add to do that? The page is www.kempruge.com The WP Forums never seem to be too helpful for me, but Moz always is! Thanks in advance, Ruben

Will google penalize a website for using a table layout?
I just got a new client today and his entire website layout and structure is using tables instead of divs. This client is on a tight budget and wants to avoid unnecessary hours for re-coding the website, but at the same time he wants me to improve his SEO organically. This is the first time I've been asked to do work on an existing website that uses pure tables for the entire layout and I'm wondering if this effects the SEO in any way. So my question is, will tables effect rankings and SEO in any way?

SEO Issues From Image Hotlinking?
I have a client who is hotlinking their images from one of their domains. I'm assuming the images were originally stored on the first domain (let's call it SiteA.com) and when they were putting together SiteB.com, they decided to just link to the images directly on SiteA.com instead of moving the images to Site B. Essentially hotlinking. Site A is not using the images in any way and in essence is just a gateway for their other sites and in this case a storage for their images. Â It doesn't use those images at all, so it really doesn't get any benefits of the images being referenced since I read that Google sometimes counts that hotlinking as a "vote" for the original image. But again, since ite A doesn't use the images that are being hotlinked at all, there's no benefit for Site A. My concern is that it's affecting their SEO for Site B because it makes it look like Site B is simply scraping data by hotlinking those images from Site A. Their programmer suggested creating a virtual directory so that it "looked" like it was coming from Site B. My guess is that Google can see this, so then not only will it look like Site B is scaping/hotlinking images, but also trying to hide it which may send up red flags to Google. My suggesstion to them was to just upload the images correctly into their own images directory on Site B. They own the images, so there's not any copyright issue, but that if they want proper SEO credit for that content, it all needs to be housed on the correct server and not hotlinked. Am I correct in this or will the virtual directory serve just as well?
