Search engine optimization (SEO) or search engine marketing (SEM) is among the most productive and most affordable marketing techniques for 2017 and beyond. With a lot of competition in any marketplace, small business owners are looking for more potent strategies when spending their hard earned dollars on advertising. The optimum solution is SEO, which provides the best return on investment (ROI) when it comes to online marketing. In case you are not using SEO, you are losing a big slice of profits over time. Your customers are ethically stolen by the competition that uses effective SEO solutions to boost the brand awareness and conversions of their own business. This is the most important reason why you should invest in professional SEO services without further delay.

SEO offers the chance to target your customers based upon their search intent. Using this method you receive highly targeted visitors when compared with a lot of the other online marketing techniques, such as email marketing and pay per click services. If you have a product or service that a consumer wants, you need to create your ad copy and website landing page in a manner that accommodates the consumer’s needs. This is the reason why SEO is indeed great at attracting highly targeted prospects to your business website. Thus, SEO is paramount to boosting the online presence of your respective business. Once your business website is optimized, it will achieve greater rankings in major search engines like Google and Bing, allowing consumers to find your website when searching for the very products and/or services that your business provides. Therefore, your decision to use SEO will improve your brand’s awareness and increase your conversions, which would improve long term profits. The truth is, there is no better method to increase the brand knowledge of your enterprise than applying effective SEO methods.

How do I Find a Professional SEO Company?

With so many SEO companies in the marketplace, how do you select the best SEO company for your business? As with any service provider, you need to perform extensive research when choosing the right SEO company. If your business is located in Pasadena or anywhere else in the United States, there’s only one professional SEO company that offers an ironclad money back guarantee for all their SEO and digital marketing services. SEO Trust is among the very best SEO companies in the United States, and is constantly recognized as a “The Local SEO Expert.”

Exactly What is Local SEO?

If you operate any type of business in Pasadena that provides products or services to residents within Pasadena and surrounding communities, then you are obviously faced with a lot of competition within your market niche. For example, if you are a dentist that has a practice in Pasadena, then you have a lot of local competition. In fact there are hundreds of dental offices in Pasadena and thousands if you add the surrounding communities. Outside of spending a large percentage of your revenue on multiple types of advertising techniques, the most economical answer is to hire a SEO company that specializes in Local SEO, such as SEO Trust in Pasadena. SEO Trust doesn’t waste your time or precious resources in trying to get your dental website to rank nationally for major search terms (keywords) like “dentist” or “best dentist.” Could you imagine the competition for that keyword with over 150,000 dentists with practices throughout the United States?

What is a Local SEO Expert?

What sets SEO Trust apart from all the other SEO companies in Pasadena and throughout Southern California is that SEO Trust uses a proven method to rank your dental website for local search terms (keywords) like “best Pasadena dentist,” “best dentist in Pasadena,” “affordable family dentist Pasadena,” “Pasadena family dentist,” and many more. These types of search terms are known as “long tail keywords,” and SEO Trust has been able to rank client websites to the number one position in both Google and Bing for these types of keywords. Once they have succeeded at ranking the first set of local search terms, SEO Trust uses the exact same Local SEO strategies and techniques to rank a new set of keywords, with the goal of capturing the most organic (search engine) traffic for their clients as possible.

SEO Trust further solidified their reputation as “The Local SEO Expert” when they began creating and using their own mini websites to rank for the same local search terms as their client’s main website. This rare Local SEO technique has allowed SEO Trust to take over entire pages of Google and Bing under their client’s local search terms (keywords). Although SEO Trust owns these mini websites, these additional sites only promote the client’s business. If the client ever chooses to part ways, SEO Trust simply locates another dentist in Pasadena that wishes to lease the multiple mini websites that are already ranked on the first page of Google for a list of extremely valuable local search terms.

Who is Your Local SEO Expert?

Although the majority of SEO Trust clients are from Southern California, approximately 45% reside outside California, and over 40% of those reside outside the United States. The bottom line is that SEO Trust specializes in local SEO and social media marketing no matter your location, and remain extremely successful at what they do and what they continue to achieve online. If your business is need of professional SEO services, and/or you wish to surpass your local competition and take over the first page of Google using proven SEO strategies and techniques, then you need to contact SEO Trust today.

  • My company needed to update our original website to a more attractive, professional, and high functioning website that would allow us to compete in the local market and on the national stage. Their first mockup design was amazing, in fact is was everything we wanted and needed. We are so grateful for Thumbtack and how it led us to SEO Trust. David is now handling our seo needs and we are already ranking on the first page for about ten local keywords and four nationally highly competitive keywords. Best choice we made in 2017 was to hire SEO Trust!Jeffrey Holland 08/26/2017
  • I'm a new customer and SEO Trust just started working on my site so I can't really say anything yet about making more sales or anything, but I wanted to write a massive thank-you to Dr. Dave and the deal he gave me and for the two mobile apps he threw in our contract for free. Who does that kind of stuff anymore?Joseph Sellers 08/08/2017
  • I just started with SEO Trust about a week ago and even though Dr. Thornton and his staff just started making all their seo changes to my website, I just wanted to say that it has been a real pleasure to deal with a professional like Dr. Thornton.Christopher Mann 07/11/2017
  • I had a retail website built by another company that cost me $1500 and took almost 3 months to build. I found SEO Trust on Thumbtack and David’s developers created an amazing site for me for only $700 and it only took a little less than 3 weeks. If you need a new website, call David and you will be happy with the results!Kerry Adams 06/29/2017
  • Our law firm needed to increase our customer engagement and create multiple social sites for all four of our locations. SEO Trust was able to get each of our offices ranked at the top of Google within three weeks. Our previous SEO guys couldn’t even get us on the first page of Google after paying them for well over three months. Thanks to Dr. David, our online traffic and our foot traffic have drastically increased. I highly recommend Dr. David and his team at SEO Trust.Paul Landers 06/09/2017
  • Thanks David for rebuilding our website and getting our dental office on Facebook, Twitter, and all those other social sites. I just wanted to drop in an let everyone know that we are now getting calls from new patients that saw our new website and found us on Yelp or google....we never had that before, so thank you all at SEO Trust.Sherry Wong 05/08/2017
  • My husband and I own three retail clothing stores in the San Francisco area, and two in Orange County and recently decided to expand nationally, but knew we needed to grow our online presence. My husband knew that David was a successful internet marketer and that he recently offered his tricks of the trade to businesses like ours. Within three weeks of talking with David, his team at SEO Trust had all five of our stores on the first pages of both Google and Bing and was able to get these great review videos on those first pages as well. Our online sales have gone from less than 10% of our monthly gross to well over 25% in less than a month. David truly knows what he's doing and I can't wait to see the numbers for next month!Diana Saunders 04/28/2017
  • My partner and I own five separate ecommerce sites that specialize in iPhone accessories, cameras, watches, handbags, and computers that we sell as affiliates for Amazon and AliExpress and never realized the extent of the competition for all 5 of our ecommerce sites. We got a detailed proposal from SEO TRUST and after speaking with David we signed the contract and after about 2 months all 5 of our sites got to page 1 and I know David isn't finished yet!Tim Corrasco 04/03/2017
  • As a general contractor in Los Angeles, I was never able to get my site to page one on Google no matter how many seo gigs I bought on Fiverr. SEO Trust sent me a quote over Thumbtack and it was a lot more money that buying gigs on Fiverr but I’ll be damn if Dave and his team didn’t get us to page one in less than 3 months…phone’s finally ringing!Carlos Fuentes 02/06/2017
  • Our company hired Dr. David and SEO Trust to promote all five of our restaurants in Southern California and we couldn’t be more pleased with the results. All five of our restaurants are now at the top of google and have outranked all of our competitors. In addition, Dr. David produced two professional review videos that were of such great quality that we are running them as television commercials in the local cable market. SEO Trust gave us excellent value with excellent results!Robert Smith 01/30/2017
  • We just had SEO Trust optimize our website since we were barely showing up in google even after three years of having a website. The head guy over there, Dave, told us about "schema," and that we needed this code on our site, so I hired Dave to insert that code and fully optimize our site. Thank God I did since we went from the last listing on page 2 to page 1 on google in less than 10 days. I was so impressed, I hired SEO Trust to handle all our internet support and publicity on a monthly basis. I recommend Dave and SEO Trust.Billy Barnes 01/19/2017
  • If you really want your business ranked at the top of the search engines and are looking to boost your image and get more customers and sales, then you need to call SEO Trust today! These guys were so confident they offered me a 100% guarantee, but I'm pretty sure no one's ever asked for their money back. In fact, I was so impressed with their results that I pay them every month now to keep working their SEO magic. That's how good they are. Cheers!Dave Griffen 12/23/2016
  • My wife and I have a Shopify site for clothing accessories and it wasn't getting the kind of traffic we wanted even after paying hundreds of dollars a month for Adwords, so we sent out a request on Thumbtack and got a proposal from SEO Trust. I first thought it was too much money but was impressed with David's plan to use local type keywords so we signed up and now we are showing up in google for all ten of the local words. After about 6 weeks our sales improved and now we are getting a lot more customers from google (more than Adwords) thanks to David and his local seo techniques.Kerry Mann 11/28/2016
  • Thanks guys the website looks beautiful and I just saw all the cool looking channels you built for us on Facebook, Twitter, google plus, and the two others. Well worth the money, now I can't wait to see some sales from your seo stuff!!!!Jerome Washington 11/18/2016
  • Even though my office shares media buys with Coldwell Banker corporate, I wanted to ensure that our office and all of our individual realtors were able to capture all the inquires that came from the internet. First off, it was clear that we needed to redo our entire website and graphics and then figure out a way to get google to love us. This is where SEO Trust entered the picture and took over our entire online operation, including our social media campaigns and realtor videos. Dr. David had us agree to a lot of changes, but once we got back online with the new mediums from SEO Trust, our online traffic and even our foot traffic increased by well over 30%. If you’re looking for real SEO changes, social media growth, and the production of some amazingly powerful videos, then you need Doc and his SEO Trust.Tim Cushman 10/08/2016
  • Although we are a nationally recognized art center and design college, we needed to development a strategy to introduce our name and brand to the art communities in close to thirty other states. One of our professors had dabbled in online marketing and was aware of Dr. Thornton successful reputation in the online marketing world. So, we approached Dr. Thornton at his new digital marketing agency, SEO Trust, and shared our dilemma, upon which he quickly developed a social media campaign that utilized video marketing and the results were amazing. Dr. David is a digital marketing genius and he seems to relish in challenges such as ours. Needless to say we gladly entered into a monthly contract with SEO Trust.Dennis Wilson 09/23/2016
