Home page deindexed by goole, How to determine why and how to fix

[David75]

On Wednesday I noticed our domain was no longer ranking for our key word and our product Isolator Fitness, http://isolatorfitness.com, I have been researching and not finding answers to why it happened and  what to do to fix it. We have about 800 other pages still listed. I am new to all this seo stuff, can anyone guide me in the right direction.
History about 10 days a go I went google web master tools and noticed that there were a large number of errors due to the fact the robots could not crawl our site. Looked at the site and found that Privacy button on WP was turned to block robots. I turned it on and had google re crawl the site, looked like google was not able to crawl the site for about 3 months, on Monday I did a 301 redirect to on of our other sites for another product we sell, to http://isolatorfitness.com/6-pack-bags.

This site had a good bit of back links would doing all this at one time cause this

How do I determine if we did anything wrong

Thanks

lol... I agree.

One of my competitors recently had a redesign done and the designer uploaded the new site with that tag on every page... BAM... they fell out of Google in 24 hours and we took their sales.

It took them a couple of weeks to figure it out.  Fortunately for them, when they removed the line of code they were back at previous rank in another 24 hours.

It happens

But yes, it's easy to recover the next time the crawlers visit the site, fortunately.
