This is how I got my website recovered from Penguin!!!

Hey friends, Penguin was the worst Google update and my 4 websites
went nowhere in the search results from #2, #6, #5 positions.

Acc. to Google it'll affect 3.2% of search results. The purpose
of this update was to unrank highly spammy websites or websites will spammy links.

But it's not true! A lot of people are complaining that their website had no
spammy contents and they did only whitehat SEO, but still Penguin hit their
website and it's nowhere in the search results.

But the great news is that I've got 1 of my websites recovered from Penguin.
Here's what I did and you can too:

1. Find and replace
Find on your website, the words like 'free', 'instantly', 'one time offer', 'limited period offer', 'free review copy' etc. You can replace these words
with the following words which don't look spammy (or less spammy)
e.g. Free = at no cost!
instantly = at the same time
one time offer = no long lasting offer
free review copy = copy for your review at no cost

2. Check Title, description and keyword tags.
Don't use same keywords in Title and description. For example, if your keyword
is 'make money with twitter', then use it in Title only. In description use
another similar keyword like 'twitter money' or 'money with twitter' (without the word 'make'). Most of the webmasters do a serious mistake while working
with keywords tag. They put all the possible keywords in it. That is a trigger
for the SEs. Put only 3-4 keywords there which are highly relevant with your page.

3. Keywords density.
I checked keyword density of my web pages. It was around 8% that is pretty high. I reduced it to only 2% by rewriting the lines or simply removing the
unnecessary lines from the page.

I used this tool for checking keyword density:
Keyword Density Checker - Keyword Cloud

3. Formatting
I removed all the red color fonts which were bold + 16 size (We IMers like that style). I made my website simple yet attractive. Easy on eyes and clear for
reading. I am using only 1 color for text on my website i.e. Black. Earlier, I was
using 2 colors - Red & Black.

4. Reporting to Google.
After doing all the work and making my website not look like spammy website.
I visited this page to send feedback to Google about Penguin. At this page, you can put a request to reconsider your website by submitting it again to Google SE:

EDITED: https://www.google.com/webmasters/tools/submit-url
Sorry for the confusion guys!

If deindexed earlier, Google will try to index your website again after submission.

It took around 15 days and my website is at #12 position. It means, Penguin
is not affecting it, now I'll have to do some more SEO to bring it back to the
position, where it was earlier.

Hope it helps!
Now, please don't try to create a WSO out of it

Thanks
