Welcome to the Q&A Forum

Hey Nicola, ~2700 is a huge no.

I would suggest you to talk to you programmer/developer to re-write the dynamic URLs into static, which I am sure they can easily do.

second thing, make sure to delete all the duplicate pages or use rel=unfollow. using 301 for all the duplicate pages is not a bad option but not a permanent solutions. It is better to re-write all the dynamics urls into static one, delete all the dups pages and then 301 redirect all the deleted pages to the originals.

for multilingual you can use the following code:

The tag enables you to say, “This is for Spain. this is for Germany

The rel="alternate" hreflang="es" annotations help Google serve the Spanish language or regional URL to searchers

I believe the following article can answer all your queries, which you even have not asked.

From my side, as long as the words/keywords are used genuinely, you  really need not to worry about that. There is no such think called Keyword Density, Reciprocal links as long as they are natural and genuine.

Okay, lets do it step by step.

First, if it's a product website, create a separate feed for products and submit the sitemap with Google.

if not, that may you would have separate news/articles/videos sections, create separate xml sitemap for each section and submit with Google

If not, make sure to have only search engine friendly URLs, who says rewriting 200,000+ pages is costly, compare this cost with the business you'll loose when all your products would be listed in Google. So, make sure to rewrite all the dynamic URLs, if you feel that Google might face problem in crawling your website's URLs

Second, study webmaster tool's data very carefully for warnings, errors, so that you can figure out the issues which Google might have been facing while visits your websites.

Avoid duplicate entries of products, generally we don't pay attention to these things, and show same products on different pages in different categories. Google will filter all those duplicate pages, and can even penalize your website because of the duplicate content issue.

Third, keep promoting, but avoid grey/black hat techniques, there is no shortcut to the success. you'll have to spend time and money.

Keywordspy.com and spyefu gives you the best information about your competitor's paid campaign.

Try once, and you'll never try any other tool. Personally I prefer keywordspy.com

It is better to first remove that information and once update then try adding new details.

If you want to delete any specific information that you’ve added to your page, follow these steps:

1. Make sure you're using Google+ as your page.
2. Choose Dashboard from the left hand drop-down menu and click Manage this page for the page you’d like to edit.
3. Click Edit page or Edit business information (for local pages) in the upper right hand corner of the screen
4. Click the section that you want to change. Instead of updating the information, click the X to remove it.
5. Select Save.

Please be aware that even though you’ve deleted it, some of the information you’ve added about your business may take up to 60 days to be deleted from Google's active servers and may remain in their backup systems for an additional period of time. Information that you may have added but is also publically available or from other sources won’t be removed.

It is quite common. You're safe till you're not caught.

David Liu is right, Google still not have any such mechanism which can instantly identify the bad or good. But what I don't agree with is "obeying the mantra 'build great content and they will come' will take you a long time to get where they are, if it ever does get you there"

Start targeting the top notch blogs in your industry to get referral links and recommendation, and it won't take much time to take you to get where your competitor is. Make sure the content you share bring some value to the blog force readers to share it with their social/ personal network.

My website is Adcart.com, we were no where, some 3 months back, in Google search results. But now you can enter any keyword, which comes to your mind by looking at our website and we rank in first 15 results and in top 10 for almost 90% queries. We just published in 13 high quality articles in exceptionally high quality blogs to achieve these results.

Hey!

Yes, it signifies that now you don't have that much of unnatural links, but it really doesn't mean that you now don't need to apply for re-consideration.

Google keeps on checking/ updating your link profile, so that message was flashing till the moment Google could see those links but now, when you have removed those links it has disappeared automatically. You still shall need to request for re-consideration.

You please proceed as per your plan and ignore the rest of the things, you are going just great.

Yupp, make sure you check the keywords trends with the help of Google Insight. Will really help you find some really good local keywords.

Thanks Deluxebydesign

I do have quality content and have never been involved in any black/grey SEO techniques

I've been promoting my site via guest posts, quality article marketing, PRs, newsletters, etc.

But my question is bit different, I am concrned about the competitors what if they start developing directory and spun content links for me.

Thoughts!

Yes, I did run a content link campaign for one of my PSD to HTML service website, and got good success. We just asked people to write a piece of content for us on their blog/website (genuine website/blog) and share that content with us via Twitter/facebook as a proof that you've wrote something about us and have published as well with a backlink.

In return we had offered them to HTML their design files.

This campaign was beneficial for us in many ways

• first we got some positive reviews from genuine people (Google Just LOVE Positive Reviews)

• Got natural/genuine one way backlinks

• got social media exposure/buzz/mentions as we were accepting entries through FB/Twitter only

• We also got social votes/ links and new followers, as we asked them to stay tuned to next offer

• We got a few new clients who liked our job (most important) and got huge repeat business

As long as you are managing a multilingual site, it is always recommended to use rel="alternative" even if you're redirecting your website.

For next, prev, don't use, unless you feel it is really required, as I could not find the need May be I missed something, could you be please bit more specific?

Business profile listing is nothing but listing your business in business directories, like:

crunchbase.com

bing.com/businessportal

getlisted.org and many more

And yes, you can submit your business (offline/online) in any of these directories but you should prefer only domain related directories, as you would get better results from there.

Page Rank really doesn't matter as long as the website/directory is authentic, relevant and is of high quality.

As far as the advantages are concerned so you get good referral traffic, in some cases back link as well, it also helps you to get some good reviews as most of such directories provide their customers/visitors with a functionality to vote or review any business which they have used or like. So you build a positive image among the customers and in the eyes of search engines as well.

Firs off don't don't build links for same keyword (if you're).

Second, if these links have not been crawled by Google for last 15 days, then they are not at all quality links. Though, as Erwan mentioned do check for those backlink Google Webmaster Tools, MOZ to see they these tools are able to crawl them or not. If They're also not able to crawl them then those links are of no value.
