Sudden Drop in Mobile Core Web Vitals
-

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.

I can’t understand their algorithm for core web vitals. I have made some technical updates to our website for speed optimization, but the thing that happened in the search console is very confusing for my site.

For desktops, pages are indexed as good URLs
while mobile-indexed URLs are displayed as poor URLs.
Our website is the collective material for people looking for Canada immigration (PAIC), and 70% of the portion is filled with text only. We are using webp images for optimization, still it is not passing Core Web Vitals.I am looking forward to the expert’s suggestion to overcome this problem.

@rwat Hi, did you find a solution?
-
Yes, I am also experiencing the same for one of my websites, but most of them are blog posts and I am using a lot of images without proper optimization, so that could be the reason. but not sure.
It is also quite possible that Google maybe adding some more parameters to their main web critical score.

Unsolved Capturing Source Dynamically for UTM Parameters
Does anyone have a tutorial on how to dynamically capture the referring source to be populated in UTM parameters for Google Analytics? We want to syndicate content and be able to see all of the websites that provided referral traffic for this specific objective. We want to set a specific utm_medium and utm_campaign but have the utm_source be dynamic and capture the referring website. If we set a permanent utm_source, it would appear the same for all incoming traffic. Thanks in advance!

Solved How to solve orphan pages on a job board
Working on a website that has a job board, and over 4000 active job ads. All of these ads are listed on a single "job board" page, and don’t obviously all load at the same time. They are not linked to from anywhere else, so all tools are listing all of these job ad pages as orphans. How much of a red flag are these orphan pages? Do sites like Indeed have this same issue? Their job ads are completely dynamic, how are these pages then indexed? We use Google’s Search API to handle any expired jobs, so they are not the issue. It’s the active, but orphaned pages we are looking to solve. The site is hosted on WordPress. What is the best way to solve this issue? Just create a job category page and link to each individual job ad from there? Any simpler and perhaps more obvious solutions? What does the website structure need to be like for the problem to be solved? Would appreciate any advice you can share!

Breadcrumbs on Mobile How important are they for SEO?
Due to Poor unsightly look of breadcrumbs and the space it takes up above the fold we only employ breadcrumbs on our desktop version. Breadcrumbs are hidden from view on mobile version. However as mobile first indexing is now in play what technical SEO impacts will this have? one thing that comes to mind is crawling deeper pages where breadcrumbs made them accessible in less than 3 link clicks? But i am unsure now of the impacts of not having breadcrumbs visible for mobile version of our site.

Sudden Indexation of "Index of /wp-content/uploads/"
Hi all, I have suddenly noticed a massive jump in indexed pages. After performing a "site:" search, it was revealed that the sudden jump was due to the indexation of many pages beginning with the serp title "Index of /wp-content/uploads/" for many uploaded pieces of content & plugins. This has appeared approximately one month after switching to https. I have also noticed a decline in Bing rankings. Does anyone know what is causing/how to fix this? To be clear, these pages are **not **normal /wp-content/uploads/ but rather "index of" pages, being included in Google. Thank you.

How can I block incoming links from a bad web site ?
Hello all, We got a new client recently who had a warning from Google Webmasters tools for manual soft penalty. I did a lot of search and I found out one particular site that sounds roughly 100k links to one page and has been potentialy a high risk site. I wish to block those links from coming in to my site but their webmaster is nowhere to be seen and I do not want to use the disavow tool. Is there a way I can use code to our htaccess file or any other method? Would appreciate anyone's immediate response. Kind Regards

Bing rank drop off for multiple sites
Hi Mozzers, Seeing some wacky stuff going on on some sites I manage. In more than a few, the ranking on bing has dropped basically overnight from page one spots to not being found on the first 100 positions. Anyone else seeing similar results? Some of the sites are fairly new, some have been around for ages, some are wordpress, some are not. I've been searching for some news of a big change on bing, but keep reading about bing dropping the thin sites during black friday. In one example, I had the site set up in BWT for a while, and had a look at the data. The reports show that the pages are crawled, the index summary shows pages indexed, and there seems to be no crawl errors, but rankings are absolutely gone. Also, I can't see the sites in bing if I search "site:example.com" in bing. Here's 2 examples, the first would make sense since it's pretty thin as I havent added much content yet: http://homewindowtint.org but this one doesn't make sense to me. Sure there's a few errors, but to be dropped like a rock seems weird http://www.ahmedandsukaram.com
