Myth # 1 All meta tags are of equal importance
Some meta tags are useful while others are not. I have stated this many times. Search engines are relying more and more about what is on the website than what the tags are telling them. The description tag is used by some (but not all) search engines. The same goes for the keyword tag. Keyword tags are used more by spammers and people using software to find you as a link partner than the search engines. In my opinion, the only tags you should concentrate your efforts on are the robot tag and the description tags.

Myth # 2 You should submit your site to search engines weekly or monthly
Honestly, I never submit any site more than 1 time and sometimes I don't even do that. If you submit your site once, you're good. The engines will come back on their own. You can sometimes speed up the process of getting your site indexed by linking it to a high traffic or high PR site. The search engines will find the URL to your site and index it automatically.

Myth # 3 SEO is too expensive
Actually, SEO is probably the most cost effective form of online marketing. Organic SEO is cheaper to set up and maintain than a PPC campaign or banner advertising. With PPC and banner advertising, you pay for clicks or impressions. With SEO, all clicks are FREE. You simply pay for the set up and monitoring of your site's pages.

Myth # 4 PPC is more effective than natural SEO
In the short term...true. In the long term...false. Why, you ask? Organic SEO is preferred by traffic over 5 to 1 to PPC. People trust organic searches to return relevant results. People also know that the ads to the right of the page are sponsored ads. They have long ago figured out that anyone can bid on any term they want, as many often do, without even a hint of relevance. So, long term SEO structuring can indeed be more effective than PPC, especially when considering the preferences of search traffic. A top 5 ranking may take some time to get, but once you are there (and provided you can maintain it), you will get better results than from a PPC ad.

Myth # 5 Hiring an SEO specialist "in house" is cheaper
The problem with hiring someone in house is, they are paid hourly or by salary. Most SEO firms (Mr-SEO included), charge per item or project. It doesn't matter how long it takes us, you pay a one time charge. When you hire a firm, it's like having a team of SEO experts on your payroll. Paying a flat rate saves you money and speeds up the time it takes to complete a job. Additionally, most SEO firms (again, Mr-SEO Included) have specialists who write, submit, redesign sites, post pages, etc... Hiring one person who can do all these things competantly is highly unlikely.

Myth # 6 I can only optimize my homepage for keyterms
You can and should optimize every page on your site. Each page should have it's own keyterms, with no more than three phrases per page (preferrably one).

Myth # 7 All I need to do is write content with the correct keyword density and my site will rank well
Wrong...especially if you want to rank on Google. You will need off site SEO as well as onsite SEO. Keyword density may work on MSN (for now), but it will take more than that to rank well for all search engines.

Myth # 8 I shouldn't aim for the most competitive keywords and phrases
If the keywords you are competing for are very competitive, should you optimize your site for them? Of Course! I would optimize for some high, medium and low competitive keyterms. Cover all your bases. The worst case is that you won't rank well for the high competitive keyterms and that's ok. You can always work to improve them. Don't shy away from top keyterms just because they are competitive. You may never know how close you could rank for them unless you try.

Myth # 9 Only work with companies that give you a guarantee
Guarantees would be nice if they were worth the paper they are printed on. In fact, most guarantees from SEO firms have the same stipulation in them. This stipulation usually states that as long as they get one of your keyphrases to the top of any major search engines, they have fulfilled their end of the agreement. This is irrelevant to the competition of the term. In other words...it's easy to be number one for terms no one is competing for. Don't be deceived by high rankings listed on SEO sites as they can be misleading.

Myth # 10 SEO requires a 1 year commitment on my part
It certainly shouldn't. Don't lock yourself into a year contract with any company unless you already have an established, favorable business relationship. SEO, in most cases, should be performed on a month to month basis with a mutual understanding of the objectives and relative timetable. Often, both the long and short term maintenance contracts that many firms insist on including with each job are unnecessary. As an example...If you have a new site optimized, especially right after an update, you may not see results for three months. Why pay for maintenance in the interim time? Additionally, you may not be happy with the results of an SEO firm or even the level of service. A long term contract may only ensure that you receive a full year of bad service. So, don't lock yourself in with a year contract, at least until you are comfortable with who you are dealing with.
