      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.

        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.

        166f3e54-485f-44f4-81a5-4e05cd49dc04-image.png

        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.

              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.

                Hello! We are an online marketplace that submitted our sitemap through Google Search Console 2 weeks ago. Although the sitemap has been submitted successfully, out of ~10000 links (we have ~10000 product pages), we only have 25 that have been indexed. I've attached images of the reasons given for not indexing the platform. gsc-dashboard-1 gsc-dashboard-2 How would we go about fixing this?

                Need some help understanding SEO - Please help before I lose [pull out] all my hair

                technical seo getting beaten sites with no seo ranking 1

                I'm new to SEO, and am stubbornly trying to educate myself. I have a telescope shop in Canada, it's a small business that we run on the side. We're driving lots of traffic through FB and our outreach programs but I really want to increase our presence on search. We released a new website back in January and it killed some of our rankings. We're working our way back with a very specific set of efforts on regular SEO: Metadata and titles, although it seems that's not super relevant Building high quality backlinks and eliminating any spammy backlinks Rewriting product listings so that they are original content though I'm not sure how important this is in e-commerce Writing high quality articles and blog posts Working relevant keywords into our product pages and titles I understand that good SEO is about pushing on all the levers, and trying to make sure that your site is as valuable to the end user as possible. We're making some good progress, but I'm puzzled by the #1 shop in Canada. They don't put any apparent effort into SEO and they still rank #1 on every key product we compete with them on. I've worked with two separate, highly ranked and regarded SEO firms on this and neither has been able to tell my why this other site ranks so highly. Here's a specific example on a popular product that we both sell, the Celestron NexStar 8SE. Here’s the link to Telescope Canada’s page for their Celestron 8SE: https://telescopescanada.ca/products/celestron-nexstar-8se-computerized-telescope-11069 Here’s a link to the Celestron 8SE page from the manufacturer website: https://www.celestron.com/products/nexstar-8se-computerized-telescope Telescopes Canada has just copied and pasted. There is no original content aside from adding the shipping and return policy to the tab, and having some options for selecting accessories on the page. Here is our page: https://all-startelescope.com/products/celestron-nexstar-8se We have higher page authority, higher domain authority, and they keyword analyzer in moz says that our page is higher quality than the Telescopes Canada page. I can’t find a single metric on any tool (ubbersuggest, Moz, ahrefs, semrush) that says Telescopes Canada is a better site, or has a better NexStar 8SE product page. But they keep ranking ahead of us, and right at the top of google search. Our titles are good, our metadata is good (but I don’t think that’s been a serious ranking factor for about ten years). Our text is original, it’s relevant, we have healthy internal links to the page. According to Moz's page ranker it's 20 points higher than Telescope Canada's page. We have invensted in some excellent blog content, we’re adding new products to the website so that we rank for more keywords. All of those things are helping, but I fundamentally don’t understand why Telescopes Canada is #1 almost across the board on every key product in our market. There is something that I’m not seeing here. Can you see any metric, any tool in your toolbox that indicates why they rank at the top, or even higher than we do for in these search terms specific to that product: Celestron NexStar 8SE
                NexStar 8SE
                Celestron NexStar 8SE Canada
                NexStar 8SE Canada I have a feeling it's something technical that I'm missing, but I'm not sure how obvious it is with two 'professional' firms not finding it. I'd really appreciate any help or insight that you can offer.

                Huge drop in rankins, traffic and impressions after changing to CloudFlare

                Hi there, In October, one of our customer's programmer made a change on their website to optimize its loading speed. Since then, the all the SEO's metrics has dropped. Apparently, the change was to move to CloudFlare and to add Gzip compression. I was talking with the programmer and he told me he had no idea why that happened. Now comes 5 months later and the SEO metrics havn't come back yet. What seems so wierd is that two keywords in particular had the most massive drop. Those two keywords were the top keywords (more than 1k of impressions a month) and now its like there is no impressions or clics at all. Did anyone had the same event occur to them? Do you have any idea what could help this case?

                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.

                Too Many On-Page Links - caused by a drop down menu

                Many of our e-com sites we build for customers have drop down menus to help the user easily find products without having to click - Example: http://www.customandcommercial.com/ But this then causes the report to trigger too many on page links We do have a site map and a google site map So should I put code in place not to follow the drop down menu link items or leave in place?

                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
