Dear Google,
Following the advice on Matt Cutts' blog, I am contacting you via this form.
Yesterday after years of sitting at around #5 - #10 for the search phrase "periodic table of elements" our webpage
http://EnvironmentalChemistry.com/yogi/periodic/ plunged from page 1 to page 5. My periodic table is one of the oldest periodic tables on the Internet and is one of the primary reference sources for large numbers of the periodic tables that are on the Internet.
This is not a new or spammy "MFA" site with little to no original content. This is an old very well established and respect website has been on line since 1995 (switched domains to
http://EnvironmentalChemistry.com in 1999) with mountains of original content and original articles written by highly qualified professionals (site development timeline at:
http://EnvironmentalChemistry.com/yo....html#History).
Now I realize that you say this happens due to the automatic nature of your algos, however, I saw the same plummet across wide swaths of our site and yesterday our traffic fell by 2/3 from the day before. This isn't just another natural fluctuation; there was a major upheaval in the SERPs and it would appear that our site is being severely punished by the last major data push and/or back links to our site are not being recognized.
Although Google searches are showing almost no back links via "allinural" or "links" to our site I know for fact that there are thousands to tens of thousands of links to our site (excluding forum sigs and our own sites) including high quality links from .GOV, .EDU and .MIL websites (e.g.
http://www.cdc.gov/nceh/publications...sing/cha02.htm,
http://ss-cbiac.apgea.army.mil/resou.../chemical.html,
http://ic.arc.nasa.gov/people/neveu/...lArticles.html,
http://www.bib.ub.es/www3/3dic_quim.htm, etc). In fact the Google search
http://www.google.com/search?as_qdr=...roductions.com is showing me 114,000 results that reference my website (this excludes our own sites).
We do not buy or trade links via reciprocal link trading schemes. We do directly sell advertising on our site but the emphasis on this advertising is always about the ads targeting real users and selling this advertising is necessary for us to fulfill our primary mission, which is to produce high quality content that is educational and informative.
We work very hard to provide very high quality and original content. Even with our data sources like our periodic table of elements and chemical database, this information is based on offline research and data compilation (in fact we are currently working on our latest update for our periodic table). There are precious few website in our niche that have been around as long as our website or spend as much effort producing and making freely available the kind of content we have produced.
If there is something wrong on our site that is causing a penalty, I would appreciate knowing what is wrong. It just seems weird that a site as vast and well linked to as ours would suddenly fall so far in the serps in a 24 hr period.
Sincerely,
Kenneth Barbalace
