Disclosure of CSR on corporate websites has improved markedly during the second quarter of this year.

That’s according to research by corporate website agency Investis which analyses more than 500 corporate websites on a quarterly basis. Conducted between April and June, the Investis survey found that the overall average website score improved by some 5% - the largest quarterly increase yet seen. The CSR category was the main driver of this performance, with a 15% increase in the average score for FTSE 100 companies. There was also evidence in the survey of companies investing more in technology again, with scores in the Web 2.0 and Multimedia categories improving strongly.

There is evidence this year of much greater focus on hard data and KPIs in reporting CSR performance, with an increase of nearly 50% in the number of FTSE 100 and DAX30 companies now providing detailed KPIs and reporting against those targets.

In the overall UK rankings, Centrica took the top spot for the first time, followed by Shell and Anglo American. BP and InterContinental Hotels entered the top 10 while other notable risers include Cadbury and Standard Life. VT Group continues to head the FTSE250 rankings.
