What is your biggest mistake and biggest success in SEO?

Hello all,

This question is for all SEOs....What is your biggest mistake & success in optimizing a website for search engines?

 

Biggest mistake: When i first started out I wrote these super keyword stuffed articles.. Didn't work that well.
Biggest success: Learned how to track down and create high authority, content related, dofollow backlinks to rank well for hard keywords.

 

most people have these mistakes
- high density of keywords
- choosing high competitive keywords
- spelling mistakes of keywords
- duplicate content

 

the biggest mistake of seo use doublecate content and speelling mistake.

 

I did a hidden link test on the homepage of the largest wireless carrier in the world and got the site penalized lol

 

Creating backlinks too fast..

 

I think fast submission of directory.

 

My biggest mistake was when i started and didn't know anything about keyword density and stuffed my article with keywords and i also had less informative content.
Success was when i learned how to do proper Seo.

 

My biggest mistake, allotting each keyword of the article with a hyper-link to my company site, so eventually my blog which had good ranking for more than year got banned from the blogger.
My success, when I learnt from my mistake and done the tagging, hyper-link for my new domain site and got the month old (new) blog on first page of google

 

I think i beat everyone here.

When i finished my website in end of 2010, i decided i dont want nigerian scammers to hang around on my site, so i blocked all IP-s exept Estonian, well, that did not work out very good, Blocked google as well

 

Yes.. right ..i am agree with you..

 

I am not aware from PPC, its my mistake.
At least i am in the SEO growing industry, its my success.

 

BONG! That's a fail guy!

 

1. Publishing some content notes I forgot to rewrite - 98% of site disappeared from serps overnight.

2. Forgetting to put my target keywords in the articles I published

3. Using Wordpress plugins without bothering to find out what they actually do and understanding them properly, just because everyone says they are great.

 

My biggest Mistakes is using high density of keywords , choosing high competitive keywords and spelling mistakes of keywords .No great achievement yet.

 

My biggest mistake was choosing competitive keywords

 

This made me chuckle.

 

Mistake - Picking the wrong Keyword.
Success -Quality content

 

change a large of titles,keywords,descriptions in a short time, this is a bigger mistake.
