If I create hundreds of websites, will google punish me? The thing need to be clear is, all websites are real sites with real content and products, not sell links or some rubbish...
Ask the way around, why would Google be mad at you for creating several websites with real content/products? I don't see any problem as long the content is unique and the websites are maintained well so they add really some value to the web.
No, Google will not punish you as your sites are real, well maintained with original content, and according to Google's guidelines.. Google always respect (high rank) the kind of site which are really useful for their Users...
I find it impossible that you will be able to create 100 sites that are well-maintained and contain valuable/entertaining information. But if you are able to accomplish this, then good job! Google won't punish any of your site so long as they stay within Google's guidelines. Hope that helps. Have a good day!
No. You have to create any no. of website you want. There no limit. For SEO point of view you want to required unique content for every sites. Work under Google's guideline.
Now a days people have started treating google like some strict teacher who punishes students on their mistakes and mischiefs but at some point its true that Google Punishes websites a lot and when it does, rest assured that it can be shocking for you. Creating a lot sites was never be a problem and its still not a problem for google at all. But you have to make sure that you are doing all the right things at right time and that is what SEO is all about. If you are following google webmaster forums and emails, you will know what is right and what is wrong so give your 100% in a proper way and you will see results.
why would you want to create hundreds of websites? Just create one high-quality site with a good idea and product.
