Web Core Vitals - scores wildly fluctuate?
-
I have run lighthouse reports multiple times today, and they have bounced up and down 20 points within hours of each other. A coworker ran hist test that returned a 90 while I scored a 68, my next test was an 88? Is this a common issue. I can understand a few points, but this is insanity!

@gpainter thanks! I will check that out. My lighthouse plugin on both chrome and firefox has stopped working.
-
@dezzign Thank you! That is great stuff.
-
as well as what @Dezzign said which are excellent points you can use Googles speed test tool which inf act runs lighthouse under it, you can also use GTmetrix which can also be a great way to see how you're doing, its always good to get a couple of input points.

A couple of quick tips that may help:
- Make sure you have the site scrolled to the very top of the screen, otherwise the scores will be different, because the test leverages the visual layout you see on the screen.
So if you're scrolled down the page a bit, and then you do a test, you'll get a different result because of different layout shifts caused by the different non-critical elements taking longer to load. Also, make sure you dock the Dev tools in a different window, so the page being tested has the full normal screen size without Dev tools .at the bottom etc.
- Your co-worker might be viewing the site on a different screen size, so there may be less CLS (cumulative layout shift) happening on their screen size, which is why the scores would be different.

Inserting Keywords in Web Pages
Hello! Question: When I add chosen keywords to my site (in urls, title tags, meta description, page content, headers, etc), do I need to put the words on my webpage exactly as they appear in my keyword research? So if I searched "therapist bay area" and I want to include these keywords, for example, must I use those words in that order in a sentence or header on my homepage? Or is it enough to include each word somewhere on the page?

Implementing Schema.org on a web page
Hi all, As we know, implementing Schema doesn't change the look & feel of a web page for the users. So here is my Question.. Could we implement Schema markup on the web pages only for Bots (but not visible to users in a Source code) so that page load time doesn't increase?

Is there any decent web browser that still displays the full page title at the top of the page?
I just updated to the latest version of Firefox on my Mac and saw that they now hide most of the page title in the browser tab, like Chrome and Safari. I like to be able to see the full page title at all times (for reasons I'm sure you all understand) and that's pretty much the only reason I stuck with Firefox all these years. Now I'm looking for an alternative – any suggestions?

Ranking Fluctuations
I need your help. My rankings have been on a wild roller coaster ride since I started optimizing the site with standard on page optimization changes. (No keyword stuffing or over-optimization...) I have only made positive changes for the content on the page; I created unique descriptions for every product. I redirected some urls that weren’t readable into a more user- friendly format. I am only doing completely organic link building, really. Yet for some weird reason the rankings initially rose and then steeply fell and ever since have went back up to the top and right back to not in the top 50 results. Just to give you an example this is a graph of one of our main keywords: https://www.diigo.com/item/image/3vpdp/gd2q This is another keyword that we admittedly never were in the top 5 results but usually we were in the top 20. Check out the wild fluctuations. If it wasn't the main keyword we were going after, I would probably laugh. https://www.diigo.com/item/image/3vpdp/rcy9 I asked an expert he said he think it might be from a major issue with internal competition. The keywords that seem to fluctuate the most, have numerous landing pages that compete for the same keyword. Since we sell the same object in many many different sizes, thicknesses and colors it only makes sense that we have the same keyword on many pages. I would love someone that is an expert in this area to have a look at the site and give actionable advice so I can stop the craziness. Do you have any suggestions? Do you have anyone that you’d refer for this type of job/consulting?

Craw structure for web site about jobs?
Hi there, we have now a client who has a job offering web site.There are many craw errors in it. My question is how should the url structure in a jobs website look like and which pages should be indexed? What is the best way and tips for optimizing a job website? Now the posted jobs pages are dynamically like: examplejob.com/detail-job/1891222223/Careers-for-Mens---Womens/Experienced-Web-Design-Need I see many job websites allow their job offers to be indexed and may be this is useful because some people find jobs also when directly search in Google. Are they using dynamically urls for that? And also my related question is what happens when the job offer expires? When Google craws that page again should it be redirected to 404 page or the original job offer text should be there and just to be added info that this job offer has expired? Otherwise If only it's written that it has expired may be there will be too much duplicate content on many many pages.
