I Stopped Recommending SiteGround: Censorship, Questionable CPU Limits, SG Optimizer Doesn’t Address Core Web Vitals

Siteground review

Back in 2019, I left SiteGround after paying about 4x in upgrades to fix CPU limits (and they started having TTFB issues).

Since moving which instantly fixed both, I shared my experience on my blog. I was totally not prepared for SiteGround’s reaction.

It started with terminating my affiliate account. Then they sent a cease & desist letter referring to a non-disparagement clause in their TOS which I’ve seen other affiliates get threatened for. They police several Facebook Groups like WordPress Hosting + WordPress Speed Up which their community manager and affiliates are admins for. They use this to ban people who speak out about them, promote their service, and frequently don’t disclose they work for SiteGround.

The SiteGround Optimizer plugin has many compatibility issues which support blames on third-party themes/plugins. It also does a poor job with core web vitals (see comparison table).

In November, 2021, SiteGround’s DNS was blocked by Google for 4 days which they blamed on Google/Amazon after saying there was no blocking on their end. Yet, they came out with a “fix” 2 days later. And you must use their DNS to use SiteGround’s CDN, so good luck with that.

SiteGround isn’t the company they once were. Not just because of their declined service in multiple areas, but because they have to cover up their mess with lies, threats, and censorship.


1. Censorship

How hard is it to post a bad SiteGround review without getting flagged, banned, or sued?

Let me know what you think in the comments (I’m curious).

Imagine you spend countless hours creating content to endorse a company as an affiliate, only for them to terminate your account and demand you remove all mentions of their brand name from your own blog. I guess if you’re going to say something, maybe post it on YouTube instead?


2. Slow TTFB

Backlinko’s 2019 TTFB test showed SiteGround had the slowest TTFB of all hosts tested.

Backlinko ttfb test

When SiteGround moved to Google Cloud, they originally used one of Google’s lowest tier machine families (N1). Yet on their blog, they said “using [Google’s] service will result in high speed for our clients’ websites.”

Google cloud machine families

SiteGround later moved to N2 in 2020 and is still using this machine family to date. It should be noted that while N2 is an improvement, it’s still a “balanced” machine family and isn’t as fast as the C2 machine family which  is used on other hosts like Kinsta and Elementor’s Cloud websites.

SiteGround will deny their TTFB is slow, but independent people say otherwise:

3. Unfixable CPU Limits

Is SiteGround running bots against your site to consume resources and make you upgrade?

It certainly appears something is fishy considering countless people who originally had CPU limits on SiteGround moved away and they were fixed instantly (including myself). You can find SiteGround’s CPU limits on their hosting page when you hover over the “server resources” tab.

Most hosts throttle your bandwidth which makes your site slow and can cause 503 errors. But on SiteGround, you have to upgrade (to add resources) or they will send you an email warning and eventually take down your website. You can wait it out, try to fix it, upgrade plans, or leave.

  • Wait it out – your website will continue to be down until your CPU seconds are reset.
  • Fix it – follow my guide on reducing CPU, but there’s no guarantee you can actually fix it and SiteGround will never blame it on their own service. They’ll probably tell you it’s an issue with caching, scripts, bots, cron jobs, or plugins. Make sure you check error logs too.
  • Upgrade – upgrading to GrowBig/GoGeek may fix it, but never upgrade to SiteGround’s cloud hosting. It’s been seen time and time again that people who upgrade to their cloud hosting still face CPU issues. When you get warnings on GoGeek, it’s 100% time to move.
  • Leave – Vultr HF, LiteSpeed, and Rocket.net are all great options to reduce CPU. Vultr HF and Rocket.net use NVMe storage (and only about 10% of traffic actually hits your origin on Rocket who offloads most of it to Cloudflare). LiteSpeed is more efficient than Apache and NGINX. Many hosts use Redis which uses memory more efficiently than memcached.

4. SG Optimizer Lacks Features With Compatibility Issues

SiteGround Optimizer is good for caching (dynamic, file-based, memcached, Cloudflare full page caching). It is not good for core web vitals.

That’s why if you use SiteGround Optimizer, you should only use it for caching then use a separate plugin like FlyingPress to handle everything else (make sure file-based caching is only enabled in 1 plugin). Perfmatters also addresses most lacking features in SiteGround Optimizer.

It also has compatibility issues which support constantly blames on other themes/plugins.

5. Their Cloud Hosting Is Awful

I’ve used it…

It’s overpriced, slow, and doesn’t fix CPU limits. I even added more CPU/RAM and was still getting CPU issues (plus my site wasn’t crazy fast after doing it). There are way better cloud hosting options than SiteGround. So once you outgrow GoGeek, I would leave immediately.

6. Google Blocked SiteGround’s DNS For 4 Days

Here’s SiteGround’s response when their DNS was blocked from Googlebot for 4 days.

In classic SiteGround fashion, they claimed no responsibility by saying “there is no blocking on our end.” But then 2 days later, they came out with a fix. SiteGround never advised customers to move to an external DNS. Many websites dropped in rankings or even disappeared from Google completely, resulting in a lot of lost time/money for customers. Feel free to look it up on Twitter. And to use SiteGround’s new CDN, you have to use their DNS. Is that a risk you’re willing to take?


7. High Renewals + Price Increases

In the old days, SiteGround’s prices were cheaper, you could get the cheaper intro price for 3 years, and they included a free migration.

They raised prices twice (once in 2018 and in 2020), you only get the intro price for 1 year, and migrations now cost $30. Prices got higher and the value of their service dropped significantly.

Siteground no value

Upon renewal, monthly pricing increases from $6.99 to $14.99 (StartUp), $9.99 to $24.99 (GrowBig), and $14.99 to $39.99 (GoGeek). Yearly, that’s $179.88, $299.98, and $539.98. So if you’re on SiteGround’s hosting now, expect a large bill once your renewal prices come into play.

In case you can’t read it, it says:

The special initial price applies for the first invoice only. Once your initial term is over regular renewal prices apply.

Don’t make the same mistake I made and use their cloud hosting. Here was my bill:

8. Declined Support

I laughed when I noticed SiteGround’s support was some of their top Autocomplete results because they’ve made it overly difficult to find. Not even a phone number of their site anymore.

SiteGround’s support has gotten worse because:

  • It’s more difficult to reach.
  • Unwillingness to help fix CPU limit issues.
  • They added a long “scope of support” disclaimer.
  • They previously disabled live chat for people who use it too much.
  • They cut off entire countries from support when they got too busy.

SiteGround hid their support, so now people people are using Google 😂


9. Harder To Transfer Away From Site Tools

Whether you like Site Tools or not, it ain’t cPanel. And if you decide to leave SiteGround, your new host may charge you to migrate everything from Site Tools.

It was released weeks after cPanel increased prices and there were many complaints of bugs and missing features. It also didn’t roll out to some clients until over a year later.  SiteGround is quick to replace something when they increase prices – but expect you to stay when they do it.


10. Attempted To Limit # Of Websites

In another attempt to increase their bottom line, SiteGround limited the number of websites you can host on each plan. This backfired and made a lot of people leave them. Although they eventually reversed this, it’s just another sneaky thing they tried to get customers to pay more.

11. Removed Service In Unprofitable Countries

Good business decision or bad ethics?

SiteGround suspended accounts from many Asian areas: India, New Zealand, Singapore, Philippines, and others.

This hurt a lot of affiliates – it was sad to see so many members of the Bloggers Passion Facebook Group (mostly Indians) hurting financially after SiteGround canceled their affiliate accounts. Even if you don’t do affiliate marketing, consider how it affected other people’s lives.

12. Forcing Customers To Use Big G

A while back, SiteGround moved customers to Google Cloud without warning.

Many people were hesitant to host their websites with one of the biggest data harvesting companies in the world. But SiteGround pulled out their excuses on how they follow GDPR, their information is still protected, blah blah blah. The bottom line is they didn’t give a warning (or an option) not to use Google Cloud. This isn’t what they signed up for, but there’s no choice.

13. TrustPilot Reviews Are Funneled From SiteGround Support

SiteGround is a classic example of why you shouldn’t always believe Trustpilot reviews. Even though they have a 4.7/5 star rating, most reviews are solicited by their own support team. This is pretty standard, but it’s also why you should take most TrustPilot ratings with a grain of salt.

14. Saying Goodbye

Well SiteGround, we’ve made a lot of money together over the years, but your company has gone completely downhill in so many ways and I honestly hope the near 3,000 customers I referred to you leave like I did. You’re honestly full of shit and I’m done sending you customers.

15. SiteGround Alternatives

Here are a few better options than SiteGround (aff links):

  • Rocket.net – look at their specs and have a conversation with Ben Gabler (that’s all it took for me). They average a <100ms global TTFB which you can measure in KeyCDN. Their free Cloudflare Enterprise is superior than Cloudways/Kinsta with full page caching, smart purging, and built their data centers in the same ones as Cloudflare (Ben was StackPath’s Chief Product Officer so that makes sense). Just to give you an idea, their plans start at $25/mo with 32 CPU cores + 128GB RAM + NVMe SSDs + Redis. No PHP worker limits because only about 10% of traffic actually hits your origin. Everything is free (no paid add-ons) and their powerful stack makes scaling affordable with plenty of resources. I asked Ben to create a coupon OMM1 to make your first month $1. Compared to Kinsta, they use about 16x more RAM, 32x more cores on staging sites, and up to 25x more monthly visits. Top performer on wphostingbenchmarks.com with a 4.9/5 TrustPilot rating too? Take 5 minutes to compare specs and see for yourself or see my Rocket.net review.

Vultr High Frequency – I was previously using Cloudways Vultr HF and this was a big upgrade from SiteGround’s cloud hosting. Also uses NVMe + Redis Object Cache Pro but Cloudflare Enterprise and their Breeze plugin need some work. Can also get expensive between the CPU/RAM, add-ons, email hosting, etc. That said, here’s 30% off 3 months.

LiteSpeed – NameHero if your visitors are in the US/EU or Scala / ChemiCloud if they’re somewhere else. All have great TrustPilot ratings and include more CPU/RAM than similar hosts like Hostinger or A2, for example, if you view NameHero’s specs page. LiteSpeed is not only faster than Apache/NGINX but can handle more concurrent connections which means less chance of CPU limit issues. Plus, the LiteSpeed Cache + QUIC combination is probably the fastest/cheapest setups you’ll find for shared hosting.

What’s Your Experience With SiteGround?

I’m genuinely curious, leave me a comment and let me know.

If SiteGround works for you, by all means keep using them. But even if they’re service was good, there’s no way I would support a company who acts like the police, makes a mess, then covers up their tracks with misinformation. The hosting/affiliate marketing space is bad enough as it is.

Someone’s gotta stand up to them even if it means threatening to get sued. Luckily, all the screenshots are right there for you to see.


Does SiteGround have a slow TTFB?

There have been numerous complaints about SiteGround's slow TTFB in Facebook groups, but many of these posts are deleted since many FB groups are moderated by SiteGround.

Why are SiteGround's prices so high?

SiteGround increased prices twice, once in 2018 and once in 2020. They have also made several changes to cut costs and increase their bottom line, such as disabling live chat and moving priority support to GoGeek. SiteGround is simply trying to increase their profits.

How do I fix CPU usage limits on SiteGround?

Disable WordPress heartbeat, block bad bots, looks for slow queries and error logs, configure a solid cache plugin, offload resources to CDNs, and be careful when using WooCommerce and slow page builders on shared hosting. However, many times you can't fix CPU usage on SiteGround and they tell you to upgrade while holding your site hostage.

What happened to SiteGround's good support?

SiteGround hid their support in the dashboard and added a long scope of work disclaimer to reduce the level of support compared to what they used to offer.

Is SiteGround a good choice in 2022?

My opinion is no. The company is going downhill and the amount of complaints about them in Facebook Groups has increased. They call their changes improvements, but independent forums say otherwise.

  1. I have seen your articles, you have a vast amount of knowledge. Now as you are always talking about the drawback of different hosts and all. Could you please recommend a host for us. I am very satisfied with your blogs. Help me out

    • I generally recommend NameHero for shared hosting or Cloudways / Rocket.net if your budget’s higher. Of course, it depends on many things like which server location you need, budget, etc.

  2. I just switched to cloudways hosting and it’s working fine.. however when I go to update the cache with the wp rocket plug-in… it just crashes the CPU… Any solution or alternative?

    • Try tweaking the preload settings and automatic cache clearing. They have helper plugins for this. Only preload important sitemap URLs, increase the preload crawl interval, and ideally use a cron job to control cache clearing. Otherwise, WP Rocket will clear the entire cache when you take specific actions.

      Cache logged-in users, separate mobile cache, and remove unused CSS features are also common causes for this. Try increasing remove unused CSS batch size (using another helper plugin) but I would use Perfmatters or FlyingPress for removing unused CSS. I already switched to FlyingPress and recommend it over WP Rocket.

  3. Wow, I’m glad I read this. I was going to move to SiteGround in the next few weeks. I’ll have to rethink now.

  4. 100% agree, Siteground sucks.
    It seems that Every single WordPress group on facebook is controlled by Siteground or has them as a sponsor, and they delete all negative comments.
    There is one WordPRess hosting group where they will ban you for saying anything negative about siteground.
    Most reviews are just affiliate link clickbait.

    read my review/story here: https://michaels.me.uk/siteground-review/

    • Yep, careful or they might threaten to sue you too! Check their affiliate TOS. Already happened to me. I’ll be publishing screenshots on their censorship attempts soon so more people know. If they put more effort into improving their hosting instead of shutting people up, maybe they would actually be better.

  5. I cant believe you didnt mention thier inode scam, I have 3 years left on my plan with them and am leaving.
    I went to dream host which has unlimited inode

    • Most shared hosts have very limited inodes which usually become a problem when you bundle web/email hosting together.

      Even hosts advertising unlimited inodes (bandwidth, or whatever) typically have hard limits in their TOS/hosting agreements. Is this what you’re referring to? Not that I agree with it but this is common practice with what I’ll call “mainstream hosts.”
