Welcome to the Q&A Forum

This is a good article on adsense layouts with some examples:

Bottom line, you want to keep your above the fold ads to a minimum and make sure that your content-to-ad ratio is high.

If you go to the media page, you should be able to edit it to give it whatever title you want (will be post_name/your_title).

A good alternative plugin is All-In-One-SEO. That should take care of most the SEO issues with Wordpress.

An "areas served" is probably the best approach, since you don't want a big spammy footer that is present on every page (remember, every link on a page lowers the value of every other link on a page). You can highlight a few of the larger/most popular areas in your sitewide nav, but I would avoid linking to every single one of them.

Google does treat pages with parameters as separate pages. The best way to avoid this is by not linking to pages with no parameters like example.com/page? Redirecting something like this would be tricky, so I would recommend just putting in a canonical tag in the header for parameter pages that don't significantly change the content of the page.

Where are these pages being linked from? If you want these pages indexed, you may want to try making them more prominent in your site's navigation and architecture. Listing them in a sitemap can help them get discovered by Google, but actually linking to them from your site will have much more impact.

Also, I notice that the site is only pagerank 2, and already has 5000+ pages indexed in Google. Google limits the number of pages it indexes for sites based on their pagerank, so you may want to consider improving your PR so Google indexes more pages from your site.

Google will continue to crawl your old URLs as long as links to them exist, so you will want to keep those 301s in place for as long as those links exist. Does that make sense?

It's not that Google will crawl a URL, see that it is being 301'd and never crawl that URL, Google will continuously crawl that URL as long as it is being linked to, and you need to have the 301 in place to tell Google that the page has moved.

You need to keep those 301s in place as long as you have links pointing to the old site that you want to get credit for. If you can contact the owners of the sites that are linking to your old site and get them to change the links, you can remove the 301s. Otherwise you will want to keep them in place.

Bing doesn't really have an equivalent for Panda or Penguin, so some of the tactics that used to work in Google (which will now harm you) can still work in Bing. Both sites take into account similar ranking factors but have different indices and different weightings for the factors. I like to think of Bing as being 1-2 years behind Google in terms of sophistication.

Microsites can be a good strategy in many instances.

The main case if you want to create a small site around a single use like downforeveryoneorjustme.com. People will often link to small microsites like this because of the novelty, and social sites like reddit are more likely to promote the site if it's a standalone rather than a part of your commercial site.

Another use case for microsites is if you want to create a site that is off-brand from your main site. For example, you might be a law firm that wants to create a meme tumblr or a prestigious bank that wants to target an off-brand term like "cheap loans". A microsite in this instance can allow you to target off-brand terms or use off-brand tactics without impacting your main brand.

If you have the resources, building out a bunch of microsites can be a way of targeting microniches or taking up multiple listings in the SERPs.

Note however that building out microsites doubles the work you have to do in terms of web design, content creation, and link building, but the results can be worth it if you have the resources.

Yahoo and botw are ok links if you have the budget (depending on the category), but getting high authority links from relevant sites in your niche will have more impact, and often cost you less money.

Besides the SEO link value, having a BBB logo on your site can build trust and improve conversions.

From a link building perspective, I would evaluate the link in terms of a) what your current resources are (time, money, people) and b) what other link building opportunities there are, and the quality of those links. Then pursue the highest value opportunities that you are able to, given your resources.

Matt Cutts has recently claimed that press releases won't really help with rankings, but there have been counter claims about the issue as well:

Press releases can definitely be helpful if you have something genuinely newsworthy and it gets picked up by the press.

Buying links can get you penalized. Don't do that.

Here is a great list of link building strategies if you don't know where to start:

Reddit has a lot of "subreddits" or categories. The main ones to keep track of are 'funny', 'advice animals', 'pics', and 'videos'.

You probably won't find anything specific to shipping containers or luxury cars, but the idea is to take what is popular and see if you can create your own version of it for your niche. For example, the "Harlem shake" videos were trending a couple weeks ago; it doesn't take much resources to create something like that for your own niches.

What niche are you in? Reddit is one of the best sites out there for finding great content for most niches.

It should be on the same domain if you want links to your blog to benefit your main site, and vice versa. If you have your blog on a separate site, Google will treat them as two separate sites.

It's pretty simple. Wordpress already has the concept of authors, with each author having their own bio page (www.domain.com/author/name).

So to add authorship, in your posts, make sure that the author's name in their byline is a link linking to their bio page, using the rel="author" markup. Many themes already do this automatically, but if not edit your posts.php and add it in.

Then, on the bio page just add a link to the author's Google+ profile using rel="me". That's it.

Anchor text is not dead.

Updates such as Penguin may have penalized sites with excessive, unnatural amounts of spammy exact anchor text links, but as long as you don't overdo it, anchor text still matters a lot.

To optimize your site for specific keywords, make sure all your onsite optimization is taken care of: have you keywords in your title, URL, copy, etc. Then make sure your site is relevant to the keywords you are targeting, that will get people to naturally link to you with those keywords.

Maybe you can use cookies to set the language, instead of hard coding it in the URL?

Subfolders are the optimal structure from an SEO perspective. With any other structure you will not benefit from the domain authority of having a single site, and will have to duplicate much of your SEO efforts.
