I need some seo expert service to consult about my site ranking problem. This site used to have a great ranking but its ranking has gone up-down for a year lately without known exact reason. I would prefer to discuss more details via PM. However, please read some info before sending me your PM. 1. Even I am not an SEO expert, I have an average knowledge of SEO. This site has been done a lot of white hat SEO and never involved with link exchange, reciprocal linking, selling link, hidden text, spam keyword, redirect, etc. 2. According to Google site penalty checklist here. My site is not in any condition that reflect on penalty. - The site still has its index in Google according to site: operator. - The site still has its backlink in Google according to link: operator. - The site still show number one when do search for a domain name without extension (domainname[.com]) 3. This site has full sitelinks (8) when do search for a domain name, both with and without extension. 4. This site has vary ranking in countries. When use Google.co.jp or Google.hu, this site still ranked in the first page for its specific search term with mini sitelinks (4). When use Google.com the ranking for this site is around #33 - #36 for its specific search term with no sitelink. When use some of other countries such as Google.ca then this site is not ranked in top #100 for the same specific search term. 5. From my own observation, with the help of seopenalty.com tool I found some issue correlation pattern. The site ranking has being flipped around every 10 - 15 days each cycle. Sometime less sometime more. - When the site ranking normally and seopenalty.com reported "No Penalty". It has ranked #2 for specific search terms and top 10 for many related search terms, also ranked top 10 for many long tails search term for inner pages. Those ranking are ranked in all Google countries. When do search for a domain name without extension, the domain name itself ranked #1 with full sitelinks and one sub page ranked #2 - When the site ranking fluctuated and seopenalty.com reported "Very High Penalty (10)". Its ranking for both homepage and inner pages are completely gone. It has some rarely long tail keywords for inner page but the traffic from Google dropped for 85% when this happen. Its specific search term has ranked in Google for some countries as I mentioned earlier such as Google.co.jp, Google.hu. When do search for a domain name without extension, the domain name itself ranked #1 with full sitelinks but one subpage which used to ranked #2 is gone. I need "exact solution" for this problem and not just a guess for a problem. Not for common SEO recommendation too (build links, add content regularly and such etc.). If you have solution please PM me your info and price.
