Web Core Vitals and Page Speed Insights Not Matching Scores
-
We have some URLs that are being flagged as poor inside Search Console in the Web Core Vitals report. For example, the report is saying that some pages have too many CLS issues.
When looking into things we can do to update we have noticed that when we run the same page using the PageSpeed Insights tool we are not getting the same bad scores. This is making it hard for us to actually know what needs to be addressed. Nor can we tell if a change actually fixed the issue because in PageSpeed Insights there is not an issue. Has anyone else had similar issues. If so have you found a way to fix it?

To my understanding, GSC is reporting based on "field data" (meaning the aggregate score of visitors to a specific page over a 28 day period). When you run Page Speed Insights, you can see both Field Data and "lab data". The lab data is your specific run. There are quite a few reasons why field data and lab data may not match. One reason is that changes have been made to the page, which are reflected in the lab data, but will not be reflected in the field data until the next month's set is available. Another reason is that the lab device doesn't run at the exact same specs as the real users in the field data.
The way I look at it is that I use the lab data (and I screen print my results over time, or use other Lighthouse-based tools like GTMetrix, with an account) to assess incremental changes. But the goal is to eventually get the field data (representative of the actual visitors) improved, especially since that's what appears to be what will be used in the ranking signals, as best I can tell.

Welcome Page - Forbes.com
Would love the group's opinion on the Forbes.com welcome page (http://www.forbes.com/fdc/welcome_mjx.shtml) redirects to the actual home page after 20 seconds. SEO implications for this tactic? Does it impact the home page rankings? (Positive/Negative) Any input is appreciated.

Punctuation at the Start of Page Titles
one of my clients appears to be using an exclamation mark (e.g. "! Graphic Prints By Mirrorin - Fun Childrens Graphic Prints") and to be completely honest, I have no idea if this is bad practice or if it wont have any affect from an SEO point of view? Any help would be appreciated because it is site wide, therefore if it is an issue I would like to be able to get it sorted asap! Thanks

Local on-page SEO
If it feels like you are doing something wrong, then you 'probably' are... Local on-page SEO When optimising a page for local SEO, and trying tick all the usuals boxes, you find yourself adding words like 'golf clubs leeds' which sounds awful when part of a natural paragraph of text. Does Google recognise this poor use of grammar? We try to be as creative as possible, as not to offend the visitor, but it feels wrong... any advice? Thanks

Autogenerated pages
My main product is database conversion software. As it supports tons of databases, it's fairly easy to generate thousands of landing pages simply by variating source/target database names, connection information etc. In fact, I autogenerated almost 25k pages that way. As I didn't want to jeopardize my main site, I placed all that content to a new microsite (www.fullconvert.com) which had no history and no inbound links. Results were nice - site is live two months and in second month already had 1300 visitors. Now, my question is - should I create the same thing on my (old and rather authoritative) main site www.spectralcore.com? I could use a different template to avoid duplicate content. Of course, my main concern is being penalized by Google. In my opinion, this autogenerated content is fine because it provides (tons of) laser-focused landing pages, so visitors will instantly recognize they found what they're looking for. But Google might disagree! What do you think? Is there a danger in trying to leverage authority of my main site in adding 20k+ autogenerated pages with inbound no links to them?

Faq page
We are redoing our faq page and we were trying to decide on the best format. 1. Create each question on a separate page 2. Create one page with all the question and have the questions expand 3. Create different faq category pages (like 4) and divide the questions between them From my perspective #1 seems the best ---. you can create hyper relevant content for the user and optimize each question really well Any experience with this?

Blog page outranks static page for KW -- why?
Blog page ranks 10 in Google, while the static page is on page 7. What makes it more interesting is that the blog page scores an "F" with the Term Target tool while the static page scores an "A". Static page has more inbound links and a mR/mT of 3.89/ 4.54 vs. 3.71/ 4.14 for the blog page. Any ideas on how to approach this one?
