      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! I have taken a Moz free trial and am really enjoying using this service. But, after implementing the recommended changes by Moz my rankings have really dropped. Is this normal? I was averaging around 17 but now averaging 40. Here is my website if anyone has any ideas of what I might be doing wrong, I would greatly appreciate any help.
                Thank you

                Google Not Indexing Pages (Wordpress)

                google search console indexed urls indexation

                Hello, recently I started noticing that google is not indexing our new pages or our new blog posts. We are simply getting a "Discovered - Currently Not Indexed" message on all new pages. When I click "Request Indexing" is takes a few days, but eventually it does get indexed and is on Google. This is very strange, as our website has been around since the late 90's and the quality of the new content is neither duplicate nor "low quality". We started noticing this happening around February. We also do not have many pages - maybe 500 maximum? I have looked at all the obvious answers (allowing for indexing, etc.), but just can't seem to pinpoint a reason why. Has anyone had this happen recently? It is getting very annoying having to manually go in and request indexing for every page and makes me think there may be some underlying issues with the website that should be fixed.

                Why can't google mobile friendly test access my website?

                getting the following error when trying to use google mobile friendly tool: "page cannot be reached. This could be because the page is unavailable or blocked by robots.txt" I don't have anything blocked by robots.txt or robots tag. i also manage to render my pages on google search console's fetch and render....so what can be the reason that the tool can't access my website? Also...the mobile usability report on the search console works but reports very little, and the google speed test also doesnt work... Any ideas to what is the reason and how to fix this? LEARN MOREDetailsUser agentGooglebot smartphone

                Is it good practice to still pay for Best of the Web Directory (BOTW) and other similar one's you have to pay for?

                I know that paid for links are hit by Google, but in the past these directories were okay. What about now? Thank you.

                Do web pages have to be linked to a menu?

                I have a situation where people search for terms like, say 1978 one dollar bill. Even though there never was a 1978 one dollar bill.   I want to make a page to capture these searches but since there wasn't such a thing as a one dollar bill I don't want it connected to the rest of my content which is reality based.   Does that make sense? Anyway,  my question is,  can I publish pages that aren't linked to my menu structure but that will be searchable or, am I going to have to figure out a way to make these oddball pages accessible through my menu?

                Mobile Domain Setup

                Hi, If I want to serve a subset of pages on my mobile set from my desktop site or the content is significantly different, i.e. it is not one to one or pages are a summarised version of the desktop, should I use m.site.com or is it still better to use site.com? Many thanks any help appreciated.
