Is this the cause? I was just publishing my header tag in the meta keyword but i switched that to feed more relevant keywords in meta keyword tag. This happened all over the site in 400+ pages. Now my visitors dropped in 5 days only. I am guessing this might be the reason. Let me know what to do next, should i revert to previous one or let it settle down.
title tag is more importatnt than keyword tag so if you find your site is not getting high ranking put keywords in title tag, change content of page and use anchor text.
"There is no effect in the organic traffic if you change some keywords in your meta tags". As they said the "title tag" with your keywords is the most important factor if you want a get a good ranking for your site. And other is adding keywords in your web content as to be crawl by the search engine but don't use the keyword stuffing.
Well its possible that they will go back up, or some other risks, Meta Tag changes might not only have occured, because its natural for a sudden lose of organic traffic
Just an FYI - only Yahoo and Ask.com still read the Meta Keywords (Google and MSN/Live do not) and they tend to only use them for indexing content, not really helping much in the rankings.
