League table of engineering body websites

Search engine results continue to provide most of a website's visitors. Professional bodies with stronger websites are more likely to be visited e.g. by engineering technicians seeking professional registration as an Engineering Technician (EngTech).

Which engineering body has the strongest website?

To answer this question we've considered the websites of all 55 professional bodies licensed by or affiliated to the Engineering Council, the regulatory body for engineering professionals in the UK.

Careersmart Domain Score

Our league table ranks websites according to their Careersmart Domain Score, a number from 1 to 100. This score doesn’t directly measure the quality of a website’s content or design. It reflects a number of off-site factors, the most important of which is how often the website is mentioned or linked to on social media and other websites.

A domain score measures the strength of an entire website rather than individual pages. The Careersmart Domain Score is a combination of three key metrics, with the following weighting:

  • Moz Domain Authority (50%)
  • Majestic Citation Flow (25%)
  • Majestic Trust Flow (25%)

Moz Domain Authority

Moz’s Domain Authority is useful for judging website strength compared to similar sites. It measures how well a website might rank in search results, and is a popular tool for search engine optimization (SEO). Domain Authority combines many other metrics, such as MozRank and MozTrust, into a single score from 1 to 100.

Majestic Citation Flow / Trust Flow

Majestic’s Citation Flow and Trust Flow are two fast-growing SEO metrics. These measure influence (number of websites linking back to a website) and trustworthiness (reputation of websites linking back to a website). Both are scores from 1 to 100. We've used Root Domain Citation Flow and Root Domain Trust Flow for our league table.

Trust Ratio

We've also taken into account Trust Ratio (Trust Flow divided by Citation Flow). This additional metric tells us how trustworthy a website's influence is. A Trust Ratio of less than 1 means that some of the websites linking back have not yet established a trustworthy reputation.

First Place

The leading website is the Institution of Engineering and Technology (IET), with a Careersmart Domain Score of 72. IET has the second-highest Domain Authority (81), the highest Citation Flow (55), and the highest Trust Flow (69) of all the engineering body websites. IET is also the institution with the largest individual membership and the largest number of EngTech registrations.

Top Three

Ranked 2nd is BCS, The Chartered Institute for IT, with 69. BCS ranks 3rd for Domain Authority (80), 2nd for Citation Flow (48), and 2nd for Trust Flow (66). BCS is also the professional body with the fourth largest individual membership.

In close 3rd place is the Institute of Physics (IOP), scoring 68 overall. IOP ranks 1st for Domain Authority (89), 4th for Citation Flow (45), and 15th for Trust Flow (48). IOP has the fifth largest individual membership.

Fourth & Fifth

The Institution of Civil Engineers (ICE) claims fourth place with a Careersmart Domain Score of 63. ICE has the third largest individual membership and the sixth highest number of EngTech registrants.

The Institution of Mechanical Engineers (IMechE) makes up the top five, scoring 61. IMechE has the third highest number of EngTech registrants and the second largest individual membership.

Honourable Mention

The Chartered Institute of Plumbing and Heating Engineering (CIPHE) ranks joint 13th overall, but ranks 3rd for Citation Flow (46). It is the only institution outside the top six to score in the top three on an individual metric.

CIPHE is only just within the top 20 for size of membership, so its website appears to be performing well compared to its resources. Although the website receives many trustworthy links compared with most other engineering bodies, its overall Careersmart Domain Score suggests it performs lower on other factors which contribute to search engine rankings.

Wooden Spoon

The Institution of Engineering Designers (IED) ranks 55th with a Careersmart Domain Score of 14. However, note that IED recently changed their web address from www.ied.org.uk to www.institution-engineering-designers.org.uk. A brand new domain, having few inbound links, is likely to score only 0 or 1 for Domain Authority at first, and it scores 1.

The old IED web address has a Domain Authority of 40. Using the old address, IED would have scored 34 overall and ranked joint 37th. However, they have set up a permanent redirect (called a 301) for the domain properly, and so their score will bounce back very soon. 

Trust Ratio

The top 15 websites all have a Trust Ratio of 1 or more.

Just outside the top 15, the Energy Institute (EI) and NAFEMS both score 49. However, the NAFEMS website has a Trust Ratio of 1.22 and EI's website has a Trust Ratio of 0.70. This suggests that more of the websites linking back to EI are scored low for trustworthiness. These may be sites which are not yet well-established rather than sites which are actually untrustworthy.

Size of Membership

It's noteworthy that the six professional bodies with the strongest websites in our league table also have the six largest individual memberships. The strength of their websites may reflect the greater resources at their disposal.

High-Volume EngTech Registrants

44 of the 55 engineering bodies offer Engineering Technician (EngTech) registration, and 11 of them have registered over 300 Engineering Technicians.

The average scores for these high-volume EngTech registrants are notably higher than the average scores for all engineering bodies on every metric, even with IED's outlier score removed.
