  • Do you offer guarantees google is a foreign

    Firstly, there is always a certain amount of competition, and secondly, the core updates in particular have caused great uncertainty in the SEO scene. As an SEO service provider or agency, you do your best to ensure that the customer is as high as possible. But it is dubious to give guarantees or even do you offer just promises. It can always happen that the desired effect does not occur at the desired time. The paradox is therefore: the more careful a service provider is with concrete statements, the more serious they usually are. Anyone who offers a ranking guarantee or even just a money-back guarantee actively uses this as a sales argument for their service. But what good is the guarantee if your company isn’t where it should be after 12 months.

    As a rule there is more at stake than

    Just the budget you gave the agency.Today I’m giving you a look behind the scenes of our SEO work: Using 4 cases, I’ll show you why I personally like to compare SEO with “diagnosis in the veterinary practice” – even an animal won’t tell you where it “hurts”. My colleagues often choose Japan Phone Number Data the term “detective work” and this is also completely accurate. seo detective on the search SEO detective in progress. A classic: the large number of “weird” links We start with a real classic: you do a crawl and sort by URL. As you scroll over it, sometimes even while the crawl is running, you will notice a large number of strange URLs in a certain pattern, for example something like strange URL in the crawl I think it somehow seems like art, right? Step 1: What is the start of these URLs and where do they originate

    If you notice weird URLs in a crawl

    Phone Number Data

    The first step is always the same: Find what is probably the first strange. URL with this pattern: To do this, simply sort your crawl alphabetically by clicking on the URL field. This actually works the same for China WhatsApp Number List all tools: Here’s the example of RYTE. First go to the “Indexability > Status Codes” report and then click on the “Document” column. Then you scroll to the “weird” URLs. If you have a particularly large crawl, you can also filter for the “weird” part of the URL beforehand. Find out where this original URL links to. Now click on the first origin. URL and look at the “inlinks” (a list of all URLs that point to this URL). Go to the source URL and find the link.

  • In my opinion also with duration and hours but at

    SEO reporting costs time and therefore also agency budget. This is what you have to know and want. If you are fit enough to look at the numbers regularly, then you can do without it. What is most important is that you are. Reported on useful key figures and. That you always look at the reporting even if you are already paying for it. Otherwise you can save yourself. Report Take a look at your SEO reports and have them explained to you! How do you approach a project? How would the collaboration start? I think this is a great question to actually check how a service provider works.

    We should continuously work towards this

    And check whether the goals have been achieved and the measures should be reported. In the detailed discussion you will find out what differentiates the service providers. What sets you apart from other SEO agencies? The agency should know and clarify its clear position. “We are the best” is Italy Phone Number Data nonsense, this is about the direction or the approach. How does the contact take place? Many customers who were dissatisfied with other agencies. Cite poor accessibility as a critical point. Does the agency respond to you by email or do you have a telephone number where you can reach your contact person at any time? Do you have a permanent contact person? Is it possible to meet in person.

    Do you want to be left alone and do you want

    Phone Number Data

    Not good metrics are visibility on Tool If you don’t yet know what metrics are relevant to you, ask your future agency candidates. They should be able to give you good suggestions. What contract terms Canada WhatsApp Number List are there and how flexibly can I adjust services? Contract terms of just a few months are common today. 12 or 24 month contracts used to be the norm, but are now rather unusual. Ultimately, however, this should not be a decisive criterion for or against an agency. You should only be careful if the terms are very long. If I were you, I would never start straight away with a long term. After a certain trial phase, you can certainly do this, for example to block capacities and fundamentally put the collaboration on a more long-term basis.

  • However this includes the risk of not getting any

    In any case, the agency does not owe any performance, only the result. Normally, such contracts will cost you more money in the long run. My opinion is: Work should be paid honestly and transparently for However this includes both sides. Therefore, not only billing on an hourly/daily basis should be mandatory, but also a transparent list of what was worked and when. Of course, there are (especially smaller) providers who calculate a high and sometimes a low number of hours for “1,000 euros SEO per month” and are ultimately “fair” on average even without hourly reporting. Some agency colleagues criticize me when I insist on charging by the hour. However, I wonder why? Because in the example mentioned, which sometimes offers more or sometimes less work, hourly billing would ultimately be the same for the customer and the agency.

    Moves upwards or downwards are also fairer

    For both sides. Craftsmen, lawyers, graphic designers and other professions are also paid by the hour. By the way, full-service or web agencies that build your online shop or company website usually work with Israel Phone Number Data calculated fixed prices. A fully equipped shop then costs 30,000 euros – although there is a large set of requirements and specifications. However, this is a work contract – the service provider owes you a work, i.e. a turnkey online shop. “SEO” is often included here, although these service providers usually only understand it as a basic SEO framework with which the shop can be found more or less easily. This basic framework is now often quite good, but it does not replace ongoing advice or work on a website.

    With consulting services like SEO You don’t know

    Phone Number Data

    In advance whether the customer will call three times a month or three times a day. And you can also spend an endless amount of time on SEO and basically “marketing” and never really be finished. That’s why Cambodia WhatsApp Number List most agencies in the SEO sector work with service contracts. A service is owed here, for example 12 hours of SEO per month. If the time is up, you have to pay more or you won’t continue working until the next month. How much does SEO cost? I wrote a separate article about this: How much does SEO cost? How are the measures reported? No matter how you bill, the agency should regularly list to you what specific work it has done in the last month or quarter.

  • But all of these lie in the ability of the relevant

    The difficulty (and the appeal!) of SEO is that you always have to think about different strategies and that there are many ways to achieve your goal. This also applies to in-house tools that are often used by certain agencies to create a unique selling point. “Only we have the SuperduperSEOTool2000 ” is something you often hear. It’s also logical, if it’s the agency’s in-house tool, that only this agency uses it. Of course, there are workflows that make work easier – but they are not game changers that will effortlessly overtake the competition. Anyone who says that is simply not right. So “set the machine to rank” is a myth. No agency has such a jack-of-all-trades. No tool can guarantee a good ranking. Most in-house agency tools are simply self-made reporting tools that use an API to pull data from other tools and then conveniently put it on a screen. Nowadays there is also Google Data Studio for this.

    For real but all of these lie SEO work there are enough

    SEO tool providers out there who are exclusively concerned with developing good tools. Companies like Sistrix , Ryte or Searchmetrics work with dozens of employees every day on good tools for SEOs – why should an SEO agency be able to build something better “on the side”? How do you vet Iraq Phone Number Data an agency? Questions for the future SEO agency Below you will find some useful questions from me that you can ask your future SEO agency. Many questions are not so much used as yes/no questions, but rather to correctly classify the agency . How many customers does each employee serve on average? The number can be less than 10, but also more than 100. If you are one of 100 customers, you can calculate the intensity of support. Of course, it also depends on your budget. But if, for example, you have 2 days of SEO budget per month, then the calculation doesn’t quite add up – because the contact person would then have to work 200 days per month.

    However if you only pay a very small amount

    Phone Number Data

    And only have a question every few months, then you might not be in such bad hands with such an agency. However, if you are only one of your contact’s 20 customers with a five-figure budget, then something is definitely wrong. The size of the agency By the way, the size of an agency says Brazil WhatsApp Number List nothing about its quality. Whether just 2 or 50 employees – there is something at every quality level. So far I haven’t been able to discover a preference here. How is billing done? Most agencies work on an hourly or daily rate basis, it feels like at least 95%. Personally, I find flat rates (1,000 euros per month for “SEO All in One Package”) a bit opaque. What exactly is the performance behind it? Payment per keyword is also opaque and usually degenerates into completely unrealistic calculations ( “You pay 10 euros per month for position 8 and 15 euros for position 7,” etc.). These are sales tricks that are intended to show you as a customer: You don’t make advance payments, but only pay if you’re successful.

  • Google Partner As an agency, you are always and fundamentally only a Google Partner for Google Ads , i.e. the paid advertisements from Google. Here we (including us, for example) work closely with Google and can get good advice. An agency becomes a Google Partner when a certain number of people have completed certain SEA certifications from Google Ads. However, Google Ads and organic Google search are strictly separated from each other. Neither the agency nor the client has any ranking advantage if the agency is a Google Partner. Google Partner Logo This Google Partner logo only applies to Google Ads! credentials Almost every agency lists references on their website. When it comes to references, you should make sure that they can actually be traced. For me, references from other service providers become more and more credible in this descending order: Anonymous references or references with first names only.

    References that simply mention the company

    Or name (e.g.: “BMW” or “Max Mustermann”) References with company name and personal message (e.g.: “We are very satisfied.” BMW) References with company name and name and personal message (“I am very satisfied”, Max Mustermann, Head of Digital, BMW.) The latter are the Iran Phone Number Data most difficult to obtain from the service provider’s perspective because the customer has to come out with their full name. At the end of the day, I personally don’t care too much about references. Because even if Max Mustermann from BMW is happy, I don’t necessarily have to be too. To do this I would have to know the person and what they value.

    And that in turn has to correspond to what

    Phone Number Data

    I value. When Jens Fauldrath recommends an SEO tool. I take a look at it because I know what standard he sets for tools (namely a high one). If a Mr. Müller from Siemens recommends a tool to me, I don’t attach Australia WhatsApp Number List much importance to it. Good reference? Well, I do not know… The same applies to references as to a good website. Many agencies have little or no references on their website because they simply don’t have the time and don’t see a need for it. Unique tools and super-duper SEO hacks There are no unique miracle tools in our industry that one agency uses exclusively and everyone else can’t. Of course there are significant differences in quality.

  • If you take a closer look, finding ranking criteria is

    PR measure for the two portals. As long as you don’t take it too seriously, I don’t think it’s a bad thing and the portals help so that as a layperson you can at least see a list of agencies. Alexander, the operator of If you take a SEO-Vergleich.de, just told me today that he is planning new, more precise and better criteria and he is in active exchange with the SEO community and open to all suggestions. I think that’s great and there will definitely be positive news soon. SEO competitions Winning various SEO competitions and SEO awards is not very meaningful. This usually involves being in first place for a completely new keyword, usually a newly invented word, on a specific day.

    This is where SEOs can show off their skills

    One of the first such competitions was the Hommingberger Cheetah Trout in 2005 . Such competitions were originally intended to be fun. Unfortunately, (few) agencies are now also involved here and then boast Indonesia Phone Number Data that they have won. I can still remember an SEO competition where the winner happily declared at a conference that all the effort had paid off. He freed a team of three agency employees from all other tasks for three months so that they could work around the clock to win the competition. Logically, you then have better chances than an in-house employee who occasionally joins in for fun after work. Unfortunately, the agency was known as one of the black sheep of the industry and from then on advertised. With the title of the competition it had won.

    This caused a commotion at the conference

    Phone Number Data

    Party when an angry SEO confronted the winner. There were even minor scuffles, which shows how seriously some people took these competitions. I happened to be standing close by and accidentally got pushed, which is how. I noticed the whole thing in the first place. SEOs just don’t understand when Vietnam Phone Number List someone is wrongly ranked number 1. Otherwise we are peaceful women and men. In a nutshell: The seal of the Federal Association of the Digital. Economy is the only seal in which an agency is subjected to a real and neutral examination of its working methods (working methods, customer satisfaction, etc.). Signing the Code of Conduct is a commitment by agencies to act in accordance with ethical standards. The ranking on comparison sites. If it is generated with visibility, says nothing about the quality of work of an agency.

  • Potential customers can filter on the website

    Here again the BVDW certificate but also, for example, Google reviews. Is the visibility or ranking of an SEO agency on iBusiness and SEO-Vergleich.de a good criterion for selection? Unfortunately not. From the customer’s perspective, it initially makes sense: Anyone who has a good ranking  Potential customers  for example for “SEO company” – is probably good at their job. However, SEO is a lot of work. If an agency’s order books are full due to recommendations, then it doesn’t care much about its own ranking. What for? Most people probably care a little bit, but not to the extent that you could. Many people follow the motto “ The cobblers have the worst shoes ”. By the way, I know a very good web designer who no longer even has his own website – because he gets more orders from recommendations than he can even handle.

    The situation is similar with many agencies

    And freelancers. However, even a mediocre agency can quickly achieve a good ranking if, for example, it assigns two employees exclusively to optimize for this keyword set. It becomes problematic when agencies Vietnam Phone Number Data specifically optimize for the keyword lists of iBusiness and SEO comparison in order to be high up there. So our Munich SEO agency Seocracy would have to optimize for “SEO Agency Switzerland” in order to get better rankings in the visibility of iBusiness. But this keyword is total nonsense for us because we are not a Swiss agency. Many of my SEO colleagues are a little annoyed by these visibility comparisons and every year there is a big outcry when the new rankings are published. Personally.

    I would also think it would be better if

    Phone Number Data

    Business and SEO-Vergleich.de would only list agencies in the future – without attempting to rank and evaluate them in any way based on value. There are many good agencies in the best lists. But just as USA Phone Number List many that I would not recommend to anyone. Unfortunately, visibility is not even recommended for pre-selection (“I’ll just take the best 5”). In addition: Many agencies that do poorly there or are not even listed are actually very good! But as an operator of SEO comparison or iBusiness you have to sort things out somehow. It is impossible to compress something as complex as “agency quality” into a number.

  • Der Code of Conduct SEO vom BVDW If you don’t

    you can voluntarily and as a member sign a commitment completely free of charge (non-members pay around 1,000 euros once) that you will adhere to certain rules as an SEO agency want to maintain standards. This includes transparent and serious working methods and much more. You can find the Code of Conduct here (PDF) . You can find the signatories of the commitment here. Agencies that want the SEO quality certificate must have previously signed the Code of Conduct. In the event of a (successful) complaint. The voluntary commitment will be declared invalid. To be transparent, I have to say that I am a member of the Code of Conduct Complaints Advisory Board .

    As a customer of an agency that has signed the

    Code of Conduct, you can complain to the BVDW if your agency violates the Code of Conduct. The Complaints Advisory Board will then help you find an amicable solution with the agency – or, in the USA Phone Number Data worst case, it will revoke the agency’s Code of Conduct. If the agency carries the quality certificate, it automatically loses the seal if the Code of Conduct is lost. The whole thing is more than just a signature, but a real commitment. By the way, there is also a kind of seal for this: Top 100 SEO by iBusiness Many agencies advertise with this logo, among other things iBusiness ‘s Top 100 SEO service providers list shows those service providers that receive the highest visibility rankings for a specific keyword set ( linked here ).

    The following factors are also taken into account

    Phone Number Data

    Seal of quality of the company in the SEO area (e.g.: BVDW SEO certificate) SEO lectures given by employees at conferences or industry events in the 12 months before the end of the survey period The UK Phone Number List number of employees Participation in trade fairs and specialist conferences as an exhibitor or sponsor You can find the list of the top 100 SEO service providers here . SEO-Vergleich.de Another widely seen seal is that of SEO-Vergleich.de. Here, too, there is a visibility ranking that is publicly visible . The criteria are similar to iBusiness, here too there is a list of keywords such as “SEO agency” or “keyword research” that are included in the ranking . You can also present yourself as an agency and provide further information on the respective provider profile .

  • You have to submit case studies that are evaluated

    FAZ and a few other agencies are represented there . “Collaboration” is not possible because the case studies are first anonymized after submission by a BVDW employee before they are given to the expert advisory board. So the people on the expert advisory board don’t even know who you have to submit they are evaluating. As an agency, you also have to name specific customers who are then surveyed by independent employees (from the BVDW) about their satisfaction with the collaboration. The application process is a lot of work for applicants as well as for the expert advisory board (which, by the way, works on a voluntary basis!) and costs money, but it ensures transparency in the market. BVDW quality certificate.

    You can get certified for SEO strategy

    On-page and off-page. Agencies that do not do link building (like us) are also not qualified for off-page. I think that’s a UK Phone Number Data bit of an unfortunate solution – but that’s the biggest weak point of the certificate. It also costs around 1,500 euros to get certified and you need a minimum turnover of 250,000 euros per year as well as three SEO employees with proven qualifications. That’s why the certificate is not so practical or too expensive, especially for very small agencies. In addition, from the BVDW’s perspective, one cannot guarantee that an agency with, for example, only two employees will actually remain consistently good throughout the certification period.

    Because if one of the two leaves the company

    Phone Number Data

    The quality can of course decrease significantly. You can find the list of currently certified agencies here . There are currently “only” 31 agencies. Of course, this is only a small part of the SEO agency landscape UAE Phone Number List in Germany. Here I would like to see more marketing budget from the BVDW to make the certificate better known. However, I can actually highly recommend this list of 31 agencies. There are actually a lot of good agencies there that I personally really value. I have known and recommended Eology , Gettraction .And Morefire for the longest time and best. But you should definitely take a look at the others too.
