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.

Shifting target keyword to a new page, how do we rank the internal page?
I have been targeting one keyword for home page that was ranking between the postilion 6-7 but was never ranking on 1st as there were 2 highly competitive keywords targeted on the same page, I changed the keyword to an internal service page to rank it on 1st, I have optimized the content as well but the home page is still ranking on 11th, how do I get the internal page rank on that keyword

Home page keyword in url
I have been looking into SEO for a few weeks now trying to perfect a homepage. Going through various sources on MOZ, and other examples out there on the internet, I keep seeing that you should have your keyword in the URL of the page. The homepage is the page most people want to rank the highest in google searches, however, you cannot put the keyword in the URL as most home page URLs are simply /. Should I actually make the home like this: www.example.com/key-word-example? I would imagine this would not be the normal for many users and would seem like it's not the home page.

Listing all services on one page vs separate pages per service
My company offers several generalized categories with more specific services underneath each category. Currently the way it's structured is if you click "Voice" you get a full description of each voice service we offer. I have a feeling this is shooting us in the foot. Would it be better to have a general overview of the services we offer on the "Voice" page that then links to the specified service? The blurb about the service on the overview page would be unique, not taken from the actual specific service's page.

URL for location pages
Hello all We would like to create clean, easy URLs for our large list of Location pages. If there are a few URLs for each of the pages, am I right when I'm saying we would like this to be the canonical? Right now we would like the URL to be: For example
On-Page Optimization | | Ferguson
Domain.com/locations/Columbus I have found some instances where there might be 2,3 or more locations in the same city,zip. My conclusion for these would be: adding their Branch id's on to the URL
Domain.com/locations/Columbus/0304 Is this an okay approach? We are unsure if the URL should have city,State,zip for SEO purposes?
The pages will have all of this info in it's content
BUT what would be best for SEO and ranking for a given location? Thank you for any info!0 -
Page speed tools
Working on reducing page load time, since that is one of the ranking factors that Google uses. I've been using Page Speed FireFox plugin (requires FireBug), which is free. Pretty happy with it but wondering if others have pointers to good tools for this task. Thanks...
