Welcome to the Q&A Forum

Since 2 / 3 years I have been doing work a client of mine. I have been building a good reputation and also a lot of top 10 / top 5 positions for mayor keywords. Starting about 4 to 12 weeks ago the positions have been dropped some due to (very) new competitors. My questionnaire is this: The client had everything better, also when I use the SEOmoz analyses. The only difference now is; the new competitors have made massive links in very short time, that making 2 things: more links than my client and also beating my clients positions. These domains exist since 3 to 9 months. What I am trying to figger out is; 1. How do they make 250.000 links in this time? (safe and so quick) 2. How does only this effect the SERPs so much? 3. If they continue this, Will they keep climbing up or get à penalty? Love to hear some advice. Thanks,
