Avoiding Future EMD Updates For Existing And New Sites: Your best bet is to avoid the five characteristics listed above for any domain. Otherwise your site will be caught in a future rerun of the EMD Update filter and will suffer the consequences, because all domains may rank well for their EMQ and be suspected of abusing the boost. So I am strongly recommending, from now on, to: • not worry about the domain name on which the site is, depending on a boost is asking for future trouble with a rerun of the EMD Update filter, • create larger sites with many indexed pages and avoid “thin†sites dedicated to ranking for a single term, • create backlinks with very diverse sources, • reduce the percentage of anchor texts with any one term to less than 20% and for the EMQ less than 15%, • point more than 50% of all back links at internal pages, • make sure the backlinks dofollow/nofollow ratio looks natural and not over optimized – certainly less than 50% of all links should be dofollow.
This is a great informative post and I would like to add if your Core website is an EMD just by chance then do not worry because as long as you have done your SEO correctly and not abused the system then you will not get any problems. Keep it as close to white hat as possible. I have clients who have an EMD as their core website and not had a problem with this because they have stayed away from raw black hat.
First two points mentioned are highly relevant to EMD updates worth considering. Thanks a lot for the same
