Welcome to the Q&A Forum

Hey There, Our crawler should definitely pick up any changes that were made before the most recent crawl began, so this definitely seems a bit strange. I am going to run your site through our Crawl Test toll to see if the pages are still being reported with the Missing Meta Description error, but I need to know which campaign you are having issues with. If you don't want to include the campaign name in this public forum, you can just let me know the initials for the campaign name. Also, it would be helpful if you can let me know when the meta descriptions were added to your site so I can check into whether or not the crawl had already begun by that time. I look forward to hearing back soon. Chiaryn Help Team Ninja

Thanks all - will give those options a try and see which works the best for us.

A few things that might answer your question: Regardless of the number of competitors there is still a minimum bid requirement. I have tried to find how Google determines the minimum bid to no avail, but there is some secret sauce for this too If you are bidding on phrase, modified broad or broad match keywords, indeed your dropping the bid is probably accounting for your lack of impressions. You should look at increasing your bids for these. Quality Score. You didn't mention if any of these keywords suffer from a low quality score. If they do then this will also attribute to your ads not being shown as frequently. You mention in a comment you want to find an equilibrium to pay as little to show as much. The "Bid Simulator" often shows a nice curve where you can sometimes see a point of inflection. It somewhat follows the law of diminishing returns. I like to target an 80% acquisition with 20% lost to low CPC for impression share. I think that is the happy equilibrium you are looking for.

We have been following this closely.  Facebook has changed the calculation of check ins.....they say it is to make sure that they have a better represenation of how many people actually went to a location. You cna get some of the detail from the facebook studio blog that I have pasted below..... Essentially they are saying that when users check in to a place multiple times in a 12 hour period, it will only count as one check in. (The old model was you could get multiple check ins added to the page total for each check in.) Same is true if you upload a bunch of photos....only one credit. If you check into a place and upload a photo and then you tag several friends in conjunction with the location, then you will be counted as yourself and each tagged friend....

One of the things to consider is not only adding the misspellings to the meta tags but also using them in the URLs. I've had to get creative on something similar...not so much about misspellings but for targeting terms that are getting searched and have low competition but that my clients don't like. In the end, the URLs and tags can remain the same with the wrong spelling but the client and searchers see the correct terms. I am still testing on this--and as you know, testing is about the only thing that will tell you if it works. Wondering if creating the misspelled version of the page can be created and later changed to a 301 redirect to the right spelling? Anyone have feedback on this?

Cheers Jeff!
