With the latest Penguin changes we have looked over many of our hubs. Not to optimize, to remove unnecessary keywords and up date the summaries. We also add an update with the date of the changes.
For an instant ping, go to the search engine of your choice. Type in your writing nickname, your keywords, title of your hub, and date. Hit search and your done.
A well written summary with your keyword cluster in it, with the most important word twice in sentences which make sense to the reader is the best optimization you can do.
You can show up on a search engine with unique content alone. If you don't believe us type "lisech", "wheelinallover" or both in any search engine.
