What each one actually is
Sitebulb
Sitebulb is a technical SEO auditing tool with two versions: one you install on your own computer, and one that runs in their cloud. Both are paid monthly, or yearly at a discount. The smaller desktop plan caps an audit at 10,000 addresses and the bigger one at 500,000. There is a 14 day free trial and no card is asked for.
Fullsweep
Fullsweep is a website. You paste an address and the crawl runs on our machines. You can check a site and read the whole report before you make an account. One payment covers every site you will ever look after, with no cap on how many pages a crawl reaches.
Where Sitebulb is better than us
These are real, and they are not going to be fixed by us writing a nicer sentence about them.
It tells you more about each problem
Sitebulb's bigger desktop plan advertises over 300 hints, well past our published list, and it explains each one at length. If you want the deepest written explanation of a technical fault, they have it.
It can compare this audit to the last one
Audit comparison and scheduled audits are on their bigger plan. We check every saved site again once a week and email you when something changes, which is a simpler version of the same idea.
It draws the site as a map
Their crawl maps show the shape of a site as a picture. We do not draw anything like that, and for explaining site structure to a client it is genuinely useful.
There is a company behind it
Sitebulb is an established business with a support team and a cloud tier built for larger teams. Fullsweep is one person. If something breaks you will be emailing me, not a queue.
Where Fullsweep is better
One payment instead of every month
A monthly bill for a tool you use a handful of times a month is the thing this product exists to remove. Ours is one payment and it does not renew.
No cap on how many pages a crawl reaches
Their smaller desktop plan stops an audit at 10,000 addresses. On a paid Fullsweep account there is no page cap at all, on any site, ever.
Nothing to install, and no seat to buy
The desktop version runs on your machine and extra people cost extra. Ours runs in a browser and covers everybody in the business for the one payment.
Our rules are published in full
You can read every check we run, in plain English, on one public page, before you trust a finding. Nobody in this category publishes their rule set. We do.
