•SITE SPEED
WordPress Speed Optimization Service
Fix what is actually slowing your site down, in the order that costs you the most.
Your customers feel a slow page long before a testing tool tells you about it. You get a WordPress speed optimization service that starts with what real visitors on real phones experienced, ranks the causes by what each one costs you, then fixes them in that order.

•Why Suff Digital
Speed work run by the engineers who will be doing the fixing.

What Our WordPress Speed Optimization Services Include
Slow pages usually have several causes. We find the bottlenecks, fix them in priority order and measure the result on real visitor data.
(06)
•Real visitor data read against lab tests
We show you both. One says which pages hurt your customers, the other says why.
•Cutting what the browser waits on
The styles and scripts your first screen needs go first, so your reader sees content sooner.
•Images and video sized for phones
Your media library reprocessed into modern formats, so phones stop downloading desktop originals.
•Caching set up as one system
Page caching, database caching and your delivery network set up together, so pages arrive ready-made instead of being rebuilt for every visitor.
•Server and database response time
Slow queries and bloated startup settings traced back to the plugin causing them, then fixed at that layer.
•Marketing tags with an owner each
Every third-party script listed with an owner and a reason, then a hold-back list.
•Common causes
What actually makes a WordPress site slow
These are the six problems we are hired to fix, and why each one costs you customers rather than points on a test.
Diagnose my site •01
A slow server response before anything loads
The delay starts before the browser has asked for an image. It is your server building the page, and on WordPress that usually means uncached requests running database queries on every visit. Front-end work cannot recover that time.
02
Content that jumps while the page loads
You go to tap a link, the page shifts, and you tap an advert instead. It happens when images, fonts or banners arrive after the first paint with no space reserved. On a phone, one late arrival moves everything.
03
Files the browser loads before showing anything
A theme and plugin stack queues far more styles and scripts on every page than any one page uses, because each plugin adds its files everywhere rather than only where needed. Your reader waits through all of it.
04
Full-size photos sent to every phone
A phone downloads the whole image file no matter how small it displays it. One hero shot can cost more transfer than the rest of the page combined, for every visitor.
05
Old marketing tags still loading
Tracking scripts pile up across years and teams, and each one runs on every page load. One slow third party stalls the browser for every visitor, however fast your own code is.
06
Fast on your laptop, slow on a customer's phone
Testing on office broadband hides what dominates the mobile experience: a slower processor running the same JavaScript, on a connection that comes and goes. Google grades you on the slower visits.
Our WordPress Speed Optimization Process
(06)
Phase 01
Day 1
We pull what your real visitors experienced
We read the field data for your main page types alongside Search Console. Where a page type is too small to report, we say so rather than substituting a test number. The days and weeks marked against these steps are an estimate rather than a final schedule, and the dates we commit to are the ones in your proposal.
Phase 02
Days 2-3
We reproduce the problem on a slow phone
Each page type is profiled on a throttled connection and a slower processor, with a trace of every request. The field data says which pages hurt. The trace says why.
Phase 03
Day 4
We rank the findings before any work starts
Every finding is scored on cost, how many page types share it and the effort to fix. You approve the ranking before a line changes.
Phase 04
Weeks 2-3
We fix in batches on a copy of your site
Each batch is built and verified on a copy, with its own before-and-after measurement. Hosting-level causes are separated out, because those go to your host.
Phase 05
After the window
We measure again once the field data refreshes
We pull the real-visit data again once your fixes have landed in it, then compare it to the starting point.
Phase 06
Ongoing
We set a speed budget and watch it
We set a limit per page type for page weight, requests and browser time, then monitor it. The next tag that breaks it raises an alert.
•What slow pages cost you
Work out what slow pages cost you from your own analytics.
Before you buy any of this, compare your conversion rate on visits that loaded quickly against the ones that did not, split by device. That sits in your own analytics, and it beats any borrowed industry figure, because it accounts for your customers.
•
Your conversion rate, split by device and load speed
•
The share of mobile visits sitting in the slower group
•
What the ranked list says each fix is worth
•Keeping the gains
Why speed gains slip back, and how we stop it.
The fixes stay put, but the site keeps changing. A new plugin queues files on every page. A marketing tag lands without review. A theme update brings back a blocking stylesheet. Each change is invisible on its own, which is why the budget matters as much as the fix.
•
New plugins add files to pages that never use them
•
Marketing tags accumulate faster than anyone removes them
•
Field data lags, so a slowdown surfaces weeks later

•Frequently asked questions
Common Questions
Use Google's own two sources. PageSpeed Insights shows a field section, real Chrome user data for your URL, and a lab section, one simulated load. Google assesses the field section. Search Console's Core Web Vitals report groups that data by template, so you can tell whether it is one page or a whole layout.
