Welcome to the Q&A Forum

Billy is completely correct. Take a look at Moz's Redirection Guide for more information.

As Bryan said, be safe. It's not the original so use a canonical link element to point to the original (through the http header).

For long-tail kw positions, generally you will not see a dramatic drop. In fact, many times no drop at all. For some of the more competitive positions, you most likely will see a slight loss.  Some companies do see a dramatic drop--but most likely because of other factors. Over time, expect to regain those positions if you focus on ux.

Dan's comments were spot on. I typically launch early on a saturday morning (2am or so) and make sure everything works. If you do launch, and the site blows up, you can always switch the 'a' record to the old site (assuming it is at a different server) and troubleshoot.

Yes, the best content is usually generated by someone who knows what they are writing about. However, most clients do not have time to generate content. So I try to get the client to do an interview, write out bullet points, write notes or anything that a good copywriter could take and spin into an informative article. If the content is generated by the client and they are a good writer, that would be ideal but rarely happens.

Also, how many organic places. If dropping like a stone over 4-5 pages? Big issue, and drops like this typically have to do w/spammy links pointed to this page as Alan was eluding to.

Yes, the 301 can still impact the new site even if it's not around anymore. If the legacy site had spam, cloaking or etc and is no longer live-- should be relatively straightforward to request a review and getting it resolved. If the legacy site had unnatural links to it, and you 301 to new site, could be lead to issues to the new site. I would most likely take down the 301 and request a review to get resolved. Once resolved, do the 301. Good luck!

Yes you can via HTTP_REFERER (if using PHP). There are plenty of examples out there.

Along with what was described above, pick up some good books. Here are some of my favorites (including Avinash Kaushik's GA book):

• Art of SEO
• Search Engine Optimization (SEO) Secrets
• Search Engine Marketing, Inc.
• Inbound Marketing and SEO: Insights from the Moz Blog
• Google Semantic Search
• Web Analytics 2.0

Yes, I realize Rand has contributed to two of the above, but they are good books:)

H1 should be the main heading and reflect the landing page. It should also be unique to the site (in most cases). H2's should be subheadings, H3's sub-sub headings and so on.

Remember this is a simulation of crawling--not ranking (I believe spiders typically do find the home page first because it gets the most inbound links and etc).

I wouldn't worry about it as long as all the major the page shows up...

In adwords you can use more broad (competitive terms) in a small geographic area for one campaign. And in another use more longer-tail nationally (so if someone is looking for Dallas Luxury Condos in Michigan, the ad will still show even though the ip address is outside of Dallas).

So:

Dallas Area Campaign:

Luxury Real Estate
Luxury Condos

National Campaign

Dallas Luxury Condos
Dallas Luxury Real Estate

Definitely add it in the title of the ad:

Dallas Luxury Condos

Remember, Test, Test, Test....

Matt summed it up nicely. If you rank for a keyword, and that keyword is not in the meta description, Google will sometimes pull the snippet of where the keyword is featured in your content. So, if you decide not to change your meta description you can still try to optimize that snippet to increase ctr in serps.

Does it even exist? I have seen rankings go crazy after launch. Both resembling a sandbox and also a reverse sandbox. Is it real? I don't know, but remember Matt Cutts historically said "some things in the algorithm that may be perceived as a sandbox that do not apply to all industries".

So, I guess this perception of a sandbox is what we are talking about? I think it's tough to say, but in my experience I would say a couple of weeks to much longer.

I would be interested in what others would say!

Don't agree. Many time you have room for your company or branding and it is a good idea. It's an easy way to gain market awareness.  Also, stuffing a ton of kw's in a title can look spammy.

I will tackle the first question, IMHO I don't think these images warrant an 18 or over disclaimer. Considering the product, some may view this as over 18 though. I would see what the competitors are doing in your industry and go from there (do those firms have a disclaimer page, what type of images do they have & etc.)

To build on Joram's answer, Google will typically use your meta description if the keyword query is inside of it. If the keyword is not in the meta description, they will grab snippet(s) from the page.

I agree with Alexandru.

Another fast way is to look at the favicon. Although this can easily be replaced, if it has that yellow/red/blue/green  Joomla icon, it's Joomla.

Nope. Typically if a searcher queries a keyword and it's not in your meta description,  Google will show snippets of where it is used on your page.

Chris is correct. The best way to increase DA is to get inbound links from popular websites. This is extremely difficult, but if you have good unique content and can get it out to these places, it will boost your DA. Unfortunately, it is not simple at all.

I hate averages! A landing page should always be dedicated to fulfilling the needs of the visitors. If the visitor requires more information, add it in via inverted pyramid.
