FAQS – How We Improve Your WordPress Core Web Vitals Google Results

What types of website do you optimize?
Currently we only optimize Wordpress and WooCommerce sites

Really dumb question… How do I test my website for Core Web Vitals?
Actually most people don’t know and it’s a great question. You can test your Core Web Vitals here. We’ve linked to our results, just add your own website url.

How much do you charge?
We charge $200 USD per hour to optimize your website, no flat rates. To get your estimate, fill in the Get Started form and our team will review your website with a personalized quote.

Why no flat rates?
Every website is very different, we work quickly and we do things honestly here. Zero padding of hours

So you are going to ding me per hour? What am I looking at paying?
Tweaking simple sites can take a couple of hours, the majority of the sites we work on take 3-5 hours. WooCommerce starts at $700.. and then it goes up from there for really complicated sites that take more work and keep us up at night

Do your rates include the cost of any paid plugins?
Yes it does! Unless you have your own paid plugins, we’ll exclusively use licensed premium caching plugins that we supply to you for free under our agency licenses to optimize your website and make your site as fast as possible.

Is optimization a one-time fee? What happens if I change something on my site and pagespeed scores go down?
We optimize your website in current state and prices are inclusive of the job, but if you change something on the site down the road (new plugins, functionality etc), then we generally charge $100 USD to tweak minor optimization updates and test the site again. The reality is that when you make changes, things ARE likely to potentially break or impact your PSI scores. We offer a 30 day window to address any issues you have once we’ve started your project.

I see other companies doing it for a couple hundred bucks, why are you so expensive?
Our team of optimizers know their craft, we’ve seen it all and know exactly what to do to improve your scores. Experience goes a long way and we’re rarely surprised for even the toughest cases.

Can you guarantee 90/90+ Google PageSpeed Insights scores for both desktop and mobile?
Well… Yes and no… There hasn’t been a single client website to date that that we haven’t been able to get over 90/90+ for both mobile and desktop.

BUT – Those 90/90+ scores are lab data results only (the big green ones at the top of your PageSpeed Insights page speed tests), and quite an accomplishment already. The reality is that few other agencies out there will promise you even passing lab data at all, but let me explain further.

After we optimize your site, you may have a LCP above 2.5 seconds on mobile still, or another metric like CLS that remains in orange ‘needs improvement’ once your Google Search Console field data is updated. Without some design changes, our optimization only goes so far, and is essentially out of scope in terms of what we can do for you. This often comes down to common issues like font choices, whether your images are too big and need to be physically resized…. There are a ton of potential reasons why this goes sideways for people, and why you’ll likely see pages still showing needs improvement in Google Search Console after optimization.

Google isn’t fooling around here. Martin Splitt (@Google) stated that the rules are exactly the same for everyone – “anything that worsens user experience could be punished by Google”. Core Web Vitals in my opinion is pretty unfair for website owners, and an incredibly high bar for most to fully achieve..

It’s for these reasons that we DON’T guarantee passing field data in your Google Search Console 28 days after optimization. Nobody can guarantee that right away because it involves real humans interacting with your site. For some websites depending on the circumstances, they will never pass field data (GSC) based on current site setup and design.

So is this all for a lost cause? It sounds gloomy to be honest, but you will get rewarded for your efforts. Very few people understand how the core web vitals ranking signal actually works.

Passing lab data will get you a healthy Google SEO core web vitals boost, passing field data is the maximum search engine benefit possible and is limited to a very small percentage of websites out there right now. Every single improvement to your core web vitals means a progressive search engine ranking opportunity.

The differences between lab and field data can be better explained in a couple of real client experiences we’ve had here.

Good example from an early client that has great lab data results, but needs to make some changes to fully pass field data core web vitals
Our client is a corporate website that scores very strongly (97/99) for lab data on PageSpeed Insights, but fails core web vitals field data. Let’s take a look at why this happens.

This site is passing FID and CLS for both desktop and mobile, it’s the LCP that holds this site back because of some pretty heavy images across the top of their pages that could be a little better optimized for mobile devices. This problem actually goes a little further than simply busting out Photoshop and spending an afternoon fixing up all the site images, the blame can also be directly attributed to their hosting.

You’ll notice a high FCP that’s pretty hard to miss. Despite this company having global offices, their poorly resourced origin server without a CDN means that hosting may actually be the difference between a pass in core web vitals field data.

It doesn’t matter what theme or page builders you use, we will pass you 90/90+ overall on lab data for both mobile and desktop scores. Fixing bloated code that was never really meant to be performant is a daunting challenge every time, and getting that passing grade isn’t an easy task for anyone. Our promise to you is to achieve 90/90+ for mobile and desktop core web vitals scores in lab data only. Check out all of your direct competitors and you’ll notice that you are likely ranking considerably higher than they are (and almost any other site out there for that matter).

People that visit your site all use different types of devices, and some themes react very differently based on the user. Mobile phones at various resolutions, tablets, laptops, desktops, they interact with your site in very specific use cases and can significantly impact your field data. Depending on where they are physically located globally, that too can even impact core web vitals scores, and it’s impossible to accurately predict what field data (real users visiting your site) gets logged by Google.

Do you have any popups to collect something like email subscribers that is delayed or triggered by some sort of exit intent before visitors leave your site?

These are some of the worst sources of CLS, it doesn’t show up on lab data tests, but it definitely will on field data results from real people interacting with your site! You don’t have to be a rocket scientist to see this in action, load your site and watch the popup aggressively scroll across the screen to get your attention. You may be ultimately faced with accepting higher CLS scores or make the decision to remove it completely and lose those new email subscribers.

Never mind all the CSS and javascript bloat they inject in you page, many plugins aren’t coded properly to be compliant with core web vitals specifics and will absolutely sabotage your field data. Social media sharing, latest posts, table of contents, most plugins display differently based on the user device, and that is a real problem. Again, you are left to weigh options on whether or not to sacrifice some of your favorite plugins on your website in order to stabilize vitals.

Regretfully, for these reasons, it’s not possible for some websites under most circumstances to fully pass core web vitals field data without making serious changes. See more below. It truly gets really complicated to pass this Google test.

You’ll definitely see your green 90/90 score at the top of Google PageSpeed Insights tests, but know there is a difference between lab and field data results.

Here is another example from one of our first clients that is now doing revision work with us so they can pass for core web vitals field data.
We’re showing lab data for mobile, scoring 98/100. This website tests consistently 0 CLS for both desktop and mobile in lab data.

But in Google Search Console and origin data (field data), it fails for CLS. Most pages actually show marked as ‘needs improvement’ but how is this possible?

In this case, only 52% of the users interacting with the site experienced CLS that was less than 0.1 – We need a minimum of 75% to pass CLS in field data.

Field data represents real people interacting with the website, it turns out they added a popup and a couple of other really minor things that got flagged for CLS that would never show on lab data results. This client passes field data for LCP and FID — but we have to fix these CLS issues to pass them in field data as well.

Some of our clients are well on their way to passing their field data as well after our initial optimization efforts, but the majority of our customers require additional care to address very specific issues that can only be discovered after GSC is updated. For those clients that are trending to pass field data, they’ve already migrated to faster themes, made font changes, completely removed or replaced plugins, and optimized their images for mobile viewers as well.

Now that Core Web Vitals is officially live as of June 15th and part of the Page Experience Update, we continue to closely monitor the situation as it’s scheduled for a slow rollout and to be implemented through the end of August. Our job is to make your site as fast as it possibly can be.

But I really want to pass Core Web Vitals field data too. Can you still help me?
In the case where we’ve already got you passing on lab data, but it turns out that exhaustive optimization efforts will be needed to pass field data, extra work will be required and unfortunately that isn’t free. There are additional costs involved and often decisions will be required on your part that have to be done before we can even start working on your site again.

The hardest thing to usually pass in field data ‘measured as good in Google Search Console’ is CLS, and that’s because small shifts occur when real users interact with your page that don’t always show in lab data. These invisible CLS issues are caught and reported with your field data and very difficult to spot.

There is an additional $1000 cost to clear CLS issues in Google Search Console and can take 1-3 months to complete. Some sites can pass this on our initial optimization based on a combination of themes and plugins used without those additional costs, but the majority may not pass field data largely because of CLS.


Provided we can get your LCP, FID and CLS in good standing, field data will often surpass what Google simulates and actually give you passing Core Web Vitals scores. Performant themes, using system fonts and sizing images to deal with all device types is part of the winning formula to give your site a chance to pass field data as well. CLS is generally the trickiest one that has to be dealt with.

The issue is that it takes 28 days before we fully know whether or not your website passes on field data, Google Search Console CrUX numbers are updated with results from real people visiting and interacting with your site. It’s a ‘wait and see’ sort of thing, getting field data to fully pass core web vitals depends on many factors beyond straight optimization.

We’ve asked approximately 25% of our clients to change hosting companies before optimization work is even started (we can’t fix slow hosting). We may ask you to consider physical changes or make some difficult design concessions on your website to improve overall results. At this point when we’re striving for absolute excellence, every single performance opportunity is considered.

While it’s not responsible for us to guarantee Core Web Vitals field data scores that simply aren’t always realistic for some, we always provide full guidance to what you might want to change on your site before we can properly optimize everything for the best outcome possible.

Our singular goal is to significantly improve website performance, maximize all your Core Web Vital scores, and make every effort to get everything in the green to gain that search ranking boost. Again, we may have to make some difficult design decisions together before we can get you there.

We encourage all potential clients to set up a ZOOM call with us beforehand to discuss your options first so we can strategize a potential plan of attack.

I use a premium caching plugin like WP-Rocket and my scores are still terrible. What am I doing wrong?
See the next bullet, Wordpress caching plugins aren’t designed to fix completely broken websites

I’ve tried everything to make my website faster, what are the most important factors to improving performance?
A good theme, don’t use bloated page builders and invest some money in a decent host. Do the first two and you likely don’t need us

My GTmetrix scores are really slow, can you help?
The first thing to realize is that unless you have a pro plan, GTmetrix only measures desktop scores in Lighthouse. The only tool you should be using is monitoring the Core Web Vitals tab scores in Google Search Console. Yes we can improve your GTmetrix scores

I’m using Elementor page builder and can’t seem to improve my scores, is there anything you can do?
It’s not you. I’ve made more than a few Wordpress blogs over the years with Elementor too. In all fairness to most page builders, things have gotten much better as they make real efforts to improve their performance. We can definitely help you pass Elementor core web vitals and other (really) slow page builders, let us help get you where you need to be

Why is my mobile PageSpeed Insights score so low?
Great question and the biggest challenge for everyone. Mobile lab data from PageSpeed Insights is a synthetic test simulated with a Moto G4 device over a throttled mobile network and that can actually be slower than real-world or field data results. Things can ultimately go both ways, but usually mobile is the toughest to optimize for compared to desktop scores.

My theme is Divi and don’t understand why my website speed results are bad, what are my options?
Divi is arguably one of the biggest and most popular WordPress themes and page builders, it’s also pretty bloated. We can definitely help improve your Divi page speed results

There are Wordpress plugins that promise 90/90+ Core Web Vital scores, how is that possible?
Do you believe in magic, Google doesn’t. We actually fix the problems you have on your site, we don’t trick Google PageSpeed Insights

If I fill out the questionnaire can you tell me what’s wrong with my site?
More no than yes. Our team takes a look at your specifics and we put an hourly estimate against the work. The form is not intended for free advice, but we’re also more than happy to schedule a ZOOM call with you to discuss further how the Core Web Vitals test works

Do you need access to my website to make changes?
No. Many larger companies have strict IT policies and privacy rules that means we won’t be allowed to go anywhere near a production environment. We’re happy to make changes in dev environments, sign NDAs or write a technical document that outlines all the changes needed that an in-house developer can implement. For the rest of you, we will need access to your admin to fix everything up

Our website gets millions of visitors every month and very complicated, can you actually handle that?
Sure. Whether you are a top e-commerce website or receive heavy traffic with a complex server environment, our expert team has years of experience to meet all of your needs. Beyond the standard Core Web Vitals optimization layer, we also provide comprehensive server network audit and analysis services, advanced code and database profiling, stress testing and performance benchmarking, advanced CDN integrations and more.
