It has been an interesting few weeks.
Initially, traffic up for some sites with some good quality enquiries. These have fallen back last week and the start of this back to 'normal-ish' levels.
None of the sites i'm monitoring have lost their positions for the key phrases i'm interesed in. I can only think that it's affected other sites that were linking in. Perhaps, initially, they were doing better and have now dropped back.
Some sites have seasonal swings, so they are hard to measure, especially in such short timescales.
There have been some big events which affect traffic to an extent, and this has to be taken into account, too. I'm more interested in trends than a one-day or one-week swing, although if traffic fell off a cliff, it'd ring alarm bells.
