Go type "search box optimization".   Nuthin'

So, if these guys don't even have their own queries nailed down then they either are not very good at this or the cost isn't worth it even for them.

Honestly, this isn't going to work for most queries.  The average searcher isn't typing the words in the right order to get YourBusiness added to the end of a query.   And, if you watched in that video they had to type out these big, long, improbable, almost worthless queries (that you would probably own anyhow) just to see the brand name.   To me that was mighty convincing that this is a baloney service.  We were laughing about that here.

PDFs can pull in tons of traffic if they have high quality content.  I agree with allowing Google to index them.

PDFs can be optimized by editing their properties.  Editing the document title in properties has the optimization power of a <title>tag.</p> <p>It is probably worth the effort to look at the PDFs and plan how you can use them to drive traffic (through links) to relevant pages of your website.  Then if the PDFs get links, some of that power will pass through to the rest of your site. Breadcrumbs in PDFs will weave them into your website architecture.</p> <p>You can also sell ad space in the PDFs or place your own ads in there.  You can also place "buy buttons" in PDFs. </p> <p>There are lots of things that can be done with PDFs that most people have not thought of. </p></title>

The specific page has.....  >500 domains linking to it.

This is rocket fuel.   Irrelevant articles help lots of websites.

Find the person who wrote that article for you and give them a really nice gift.

Ask them to write another article about plants in the office.

Ask them to come up with some great photos of plants (that you are legally able to distribute as screensavers, branded lightly with your domain) and give them to people.

Advertise the new article about plants on the popular page, advertise the screen saver on your popular page.

I don't think that you are going to kill a software giant with irrelevant articles but I believe from experience that they can be very helpful to your rankings.   Plus, we make a few sales every month to people who landed on our website to consume irrelevant content - and the products that we sell are irrelevant to the content and damn few people want what is sold on that site.

I did what I asked you to do.
