At Bidmark, we love a process, especially when it comes to writing blog posts. For us, it’s never about throwing words on a page; it’s about building something that connects. As i always say, "its all about having a balance of planning and personality that helps us create content for clients that actually connects with people" and having a SEO checklist for blog posts handy is very useful to ensure you can comprehensively update your blogs to reach the results you desire.
Improving your blog's SEO involves multiple strategies to enhance its visibility and ranking and sometimes things can be missed off. With that in mind, here’s our SEO blog checklist that we use at Bidmark every day. Its full of actions you can take, based on your goals. So let's get started!
1. Add High-Quality Images
When we kick off an SEO content plan, whether it's for a client or our own site, we always start with the visuals. From experience, I’ve seen just how important the look of a page is, not just the words. The images, graphics, and overall design play a huge role in how visitors engage with your content. It’s like walking past a shop window—if the display catches your eye, you're far more likely to walk in. The same principle applies to your website.
Strong visuals immediately grab attention, make your site feel polished and trustworthy, and set the tone for everything that follows. But it’s not just about aesthetics—search engines also use visual cues to better understand your content, especially when images are properly optimised. So by starting with thoughtful, well-designed visuals, we’re not just making the site look good, we’re improving user experience, increasing dwell time, and giving SEO a solid foundation from the very beginning.
Relevance: Matching Images with Your Content
We always say that your images should tell the same story as your blog content, they’re not just decoration, they’re your visual sidekicks. I’ve learned over time that the right image can make your message click with readers in a way words alone sometimes can’t.
Here’s how we approach it:
Read & Reflect
We start our SEO checklist for blog posts by going through the content and identifying the core ideas we want to emphasise. This step shapes everything that follows — from the keywords we focus on to the visuals we choose. By understanding the message at the heart of the post, we can select images, graphics, or charts that genuinely add value rather than acting as filler. Each visual is there for a reason: to break up the text, improve readability, and reinforce the main points in a way that supports both user experience and SEO performance.
Pick or Create Images
Whether we’re sourcing or designing them ourselves, we always ask: Does this image actually support the point we’re making? We avoid those generic stock images that add nothing. Instead, we aim for visuals that feel aligned, helpful, and on-brand.
Place with Purpose
We don’t just drop images randomly, we place them where they naturally fit in the flow of the content. That way, they enhance the reader’s journey rather than interrupt it.
By being intentional with imagery, we’re not only improving engagement, we’re also reinforcing the credibility and clarity of the content itself. It’s a small step that makes a big difference.
Optimisation Speed - Without Skimping on Quality
One thing I’ve learned the hard way is that oversized images can really drag down a website’s performance. A beautiful blog post won’t matter much if it takes forever to load. That’s why we always compress our images before uploading, so pages stay fast without sacrificing quality. It’s all about hitting that sweet spot between visual appeal and loading speed. Here's how we do carry out this step of our SEO checklist:
Choose Your Tool
We tend to use tools like TinyPNG. They’re simple, reliable, and get the job done. Just drag and drop your image into the tool. It handles most file types and does a great job with bulk uploads too. Once the tool’s finished compressing, we download the optimised version. It usually cuts the file size by 50% or more without a noticeable dip in qualit
Replace & Review
We then swap out the original image on the site and run a quick visual check to make sure it still looks sharp. It’s a small tweak, but one that can noticeably boost page speed, and that’s something both users and search engines appreciate.
Image optimisation isn’t just a technical SEO task, it’s part of delivering a better experience. And from what we’ve seen, even small speed improvements can lead to better rankings and happier readers.
Alt Text: The Secret Sauce for SEO and Accessibility
I’ve come to see alt text as one of those small SEO tasks that makes a big impact, not just for rankings, but for accessibility too. It’s like a mini caption that tells search engines and screen readers what your image is about. Done right, it supports both your SEO goals and users who rely on assistive technology. Here’s how we handle it in our own posts:
List Your Key Images
First, we go through the blog and pick out the most important images, the ones that support the content or deliver key context. Not every image needs detailed alt text, but the meaningful ones definitely do.
Craft a Helpful Description
We write a short, clear description of what’s happening in the image. If it makes sense, we naturally include a keyword, but only if it fits the image. The priority is clarity and usefulness, not keyword stuffing.
Enter the Alt Text
In platforms like WordPress, there’s usually an alt text field right in the media settings. We paste our description there, keeping it concise and relevant.
Test It Out
To make sure it actually works, we use a screen reader or accessibility checker to hear how the alt text sounds out loud. If it feels confusing or vague, we refine it until it clearly conveys the image’s purpose.
In our experience, writing thoughtful alt text doesn’t just help with SEO, it shows that you care about all users. And that builds trust, both with your audience and with Google. Make sure to have this on your SEO checklist for blog posts!
File Names: Let Your Image Name Do the Talking
This is one of those simple SEO tricks we never skip: renaming image files before uploading them. It might seem minor, but I’ve seen it help search engines better understand what a page is about, especially when you’re working to rank for competitive keywords. Here’s how we approach it
Identify Your Keywords
We start by thinking about the blog’s core topic and what phrases our audience might be typing into Google. These are usually the same keywords we’re targeting in the post.
Rename the File
Instead of uploading something like IMG_1234.jpg, we rename it to something descriptive, like best-seo-strategies.jpg. It’s a quick fix, but it helps reinforce the content’s relevance to search engines.
Upload the Image
Once renamed, we upload the image using the new filename. Most blogging platforms (like WordPress) retain that file name in the media library, adding a little extra context for crawlers.
From what we’ve seen, this kind of attention to detail contributes to better indexing, and when combined with other image SEO tactics, it strengthens your overall optimisation of your blog post.
Image Formats
From experience, I’ve learned that choosing the right image format can make a big difference to your site’s performance. Not every format suits every purpose—and while WebP is a great all-rounder, sometimes JPEG or PNG is still the better call depending on what you're showing and who your audience is. Here’s how we approach image formats.
Learn Your Options
We always match the format to the type of image. For example, JPEG works well for photos with lots of colour and detail, PNG is ideal for graphics or images with transparency, and WebP is brilliant for combining high quality with smaller file sizes.
Pick the Right Format for Your Audience
If we know most of our audience is using modern browsers (and we usually check this in analytics), we’ll go with WebP for speed and efficiency. But for older devices or compatibility-heavy use cases, we might stick with JPEG or PNG to avoid rendering issues.
Convert if Needed
We use tools like Squoosh or even Photoshop to convert images. These tools let us tweak the quality so we’re not sacrificing visual appeal just to save a few kilobytes.
Double-Check & Upload
Before uploading, we always check how the image looks, especially on mobile. If it still looks crisp and loads fast, it’s good to go.
Choosing the right image format might feel like a technical detail, but in our experience, it plays a direct role in page speed, user experience, and SEO performance. It's one of those backend decisions that really pays off on the frontend.
Update and Improve Content
The second part of our SEO blog checklist is all about the content on your website. In layman's terms, this means that what you write matters just as much as how your site looks. Great content is like having an interesting conversation, it informs, entertains, and keeps your audience coming back for more. It's not only about filling pages with words; it's about providing valuable, well-structured, and engaging information that answers your readers' questions. When your content is top-notch, search engines notice it too, which helps improve your site's ranking and visibility. Essentially, good content builds trust with your audience and makes your site a go-to resource in your field. This part of our SEO checklist for blog posts involves:
Expand and Add Depth: Cover Every Angle
When we create content, we treat it like a conversation with a curious friend, engaging, informative, and leaving no question unanswered. I always start with a rough outline that covers the main topic, related subpoints, and the questions readers are likely to ask. From there, I dive into research to back up every point with facts, examples, and different perspectives, making sure no angle is missed. Each section gets expanded thoughtfully to tell a complete story, not just skim the surface. Before publishing, I review everything, or ask a teammate to, for gaps or unclear areas, filling them in so the final piece feels comprehensive, trustworthy, and genuinely helpful.
Answer User Intent: Speak Directly to Your Readers' Need
Your content should be the perfect answer to your audience's questions, much like being a trusted guide who always points in the right direction. Begin by identifying the main keywords related to your topic using tools like Google Keyword Planner or SEMrush. Next, analyse what your readers are really seeking, is it detailed information, quick tips, or perhaps a product solution? Tailor your content to address that specific intent by structuring your post so that it starts by directly answering the query, then expands into supportive details and examples. Compare your work to top-ranking content to ensure that you're meeting your readers' needs effectively.
Add Fresh Information: Keep It Up-to-Date
While evergreen content forms the foundation of a strong blog strategy, I’ve found that regularly updating posts with fresh trends, data, or studies is essential for staying relevant and building long-term trust. We schedule periodic reviews for key articles, usually every few months, so nothing goes stale. To stay ahead, I follow industry news, subscribe to trusted newsletters, and use Google Alerts to keep tabs on evolving topics. When new insights or statistics emerge, we update the content accordingly and always reference credible, up-to-date sources. I also make a point to mention the latest changes within the post itself so readers know they’re getting current, reliable information.
Break Up Content: Make It Easy to Digest
From experience, I’ve found that breaking up large blocks of text is key to keeping readers engaged, no one wants to wade through a wall of words. I like to think of content as a layered cake: easy to digest, with each slice clearly defined. We use descriptive subheadings (H2s and H3s) to guide the reader through the post, making it clear what each section covers. Short paragraphs, ideally 2 to 4 sentences, keep things readable, while bullet points and numbered lists help present information in a quick, scannable format. Whenever it makes sense, we also add visuals like images, charts, or infographics to break up the text and bring ideas to life.
Internal Linking: Create a Web of Useful Content
In my experience, internal linking is one of the most underrated yet powerful SEO strategies, it’s like giving your readers a guided tour of your best content while helping search engines make sense of your site’s structure. Whenever we write a new post, we look for opportunities to link naturally to other relevant pages or blog articles that add value to the topic at hand. We use clear, descriptive anchor text so readers know exactly what they’ll find when they click, and we make sure the links feel like a natural part of the flow. We also do regular link checks to ensure everything works smoothly, because broken links don’t just frustrate users, they send the wrong signals to Google too.
External Linking: Boost Credibility with Trustworthy Sources
When we link to external sources, we treat it as an opportunity to build trust and show that we’ve done our homework. I always aim to back up claims with solid evidence from reputable sites, whether that’s industry-leading publications, official studies, or trusted data sources. These links not only support what we’re saying but also give readers extra value if they want to dig deeper. We make sure the sources are current, directly relevant to the topic, and high quality, because linking to outdated or questionable content can do more harm than good. Done right, external linking adds credibility and strengthens the authority of your blog post.
Optimise for Featured Snippets: Be the Quick Answer
Featured snippets, the handy boxes at the top of search results, can significantly boost your visibility. To increase your chances of landing one, identify common questions people ask related to your topic by checking out “People also ask” sections in search results. Format your content for clarity by using lists, tables, or clear Q&A sections that provide concise and direct answers. Adding structured data (schema markup) where applicable can help search engines understand your content better. Monitor which blog posts are earning featured snippets, and refine your formatting and content based on what works best.
Research Competitor Pages
Next up on ur SEO checklist for blog posts is to take a good look at your competitors' pages. In plain terms, this means checking out the websites of others in your niche to see what they're doing right. By doing this, you can discover useful ideas and spot areas where you can do even better.
Competitor Analysis
Use tools like Ahrefs, SEMrush, or Moz to identify who’s ranking for your target keyword. This reveals your direct competitors and helps you understand the landscape.
Content Gaps
Look for areas where competitors might be lacking, whether it’s missing information, outdated content, or low engagement. Identify these gaps and fill them in your own blog posts to offer something more comprehensive.
Keyword Research
Analyse the keywords that competitors are ranking for. Incorporate these keywords strategically into your content to help boost your search visibility.
Content Quality Benchmarking
Assess the quality of your competitor’s content. Notice if they’re using multimedia, case studies, or expert opinions, and then strive to provide superior content in both quantity and quality.
Meta Data Optimisation
Observe how your competitors structure their meta titles and descriptions. Use this as inspiration to craft compelling, keyword-focused meta data for your own pages.
Backlink Analysis
Review where competitors are getting their backlinks from. Aim to acquire high-quality backlinks from the same or even better sources to boost your site’s authority.
Technical SEO Enhancements
When we work on technical SEO enhancements, we focus on fine-tuning the behind-the-scenes elements of a website to make it as easy as possible for search engines to crawl and understand. Think of it like designing a store that’s not only visually appealing but also intuitive to navigate. Here’s how we approach it:
Improve Page Speed
We rely on tools like Google PageSpeed Insights and GTmetrix to analyse page load times, pinpoint performance issues, and identify opportunities to make our clients’ websites faster and more user-friendly.
Mobile Optimisation
We make sure every site we work on is fully responsive and optimised for mobile users, knowing that mobile-friendliness is a key factor in both user experience and search engine rankings.
URL Structure
Keep URLs simple, descriptive, and keyword-rich (for example, /best-seo-strategies-for-2024) to benefit both users and search engines.
Schema Markup
Add structured data to help search engines understand the context of your content, which can also lead to rich snippets in search results.
Fix Broken Links
We suggest routinely audit our clients’ sites for broken links and fix them promptly, improving the user experience while making it easier for search engines to crawl and index the site effectively.
XML Sitemap
Make sure your sitemap is up-to-date and submitted to search engines via tools like Google Search Console.

Improve Readability
Use legible fonts, sufficient white space, and break up large blocks of text into shorter paragraphs to make your content more digestible.
Interactive Elements
Consider adding interactive features such as polls, quizzes, or a vibrant comment section to boost user engagement.
Minimise Popups:
Avoid using intrusive popups that disrupt the reading experience and could increase bounce rates.
